Fulltime and Professional IB Math (AA/AI, HL/SL) Tutor
Hi, my name is Denny. I am a fulltime math tutor and I focus on teaching IB Maths. I have indepth understandings of all the topics in IB math syllabus and exams. I have collected and analyzed all the IB maths past papers in the past 10 years, therefore, I can precisely help my students revise all the topics that definitely will be tested in their chapter tests and IB final exams. I have developed efficient teaching methods to help maximize students’ efforts and achieve their academic goals. I will teach my students effective learning skills so that they grasp key concepts much faster and I will teach them useful problemsolving techniques so that they can solve IB exam questions much easier. I have successfully helped hundreds of students improve grades and get accepted into their dream universities.

Proven results: average grade increase being 2+ (IB grading scale)
My productive teaching methodology and strategy are built on thousands of hours of online tutoring experience and proven results of improvements from hundreds of students. I am proud of my services which are highly recognized and recommended by my students and their parents.
 Some of recent testimonials:  
*******After Denny started tutoring me, my grades went from 4s to 6s and 7s and I scored a 7 on my final IB exams. Denny taught me all the topics, starting with basic theories and formulas. He made sure I understood the easy problems first before moving on to more complex ones. What really helped me was that Denny showed me multiple ways to solve a problem; it broadened my understanding of the topic as well as my critical thinking. I became more flexible in different questions, really applying my knowledge rather than solving a problem by a learned/memorized method. *******


*******This is coming from an IB student who failed to submit a single piece of homework in maths over my 2 DP years, and skipped 20% of my IB classes. I booked him every day for a week before my final exams and my grade went from a 4 to 7. The results speak for themselves, I cannot recommend him enough. His teaching style is phenomenal if you don't like to waste time and get shit done; he cuts out all the useless/filler crap regular teachers/other tutors often make you put up with and gets right down to the meat. He is just really good at his job. Not only does he know the material inside and out, he has made sure to fully understand the IB criterion and marking styles to make sure that he not only teaches you the math itself, but exactly how to word your answers to maximize your marks and teaches you the question formats you'll face on exams. Study smarter, not harder. *******


*******I got a 44 with a high 7 in mathematics AA HL. I am so thankful that you have been a tutor for me in this process. You have been a source of motivation for me in the process, and you have helped me clear so many doubts. You help the student discover their weak points, and give detailed solutions and explanations for complex questions Thank you very much. *******


*******Before my lessons with Denny, I was getting constant 3s and 4s at school and was having issues with the way my teacher taught me the syllabus. I am extremely grateful to have had such a delicate and skillful tutor who enabled me to reach a score of 6 at my final exams. I would have never done so well without him. When working with Denny, he would not only teach me the Mathematical concepts but he would also show me the way in which to approach each question. Throughout the year Denny and I deeply reviewed each topic of the syllabus to strengthen my understanding of several concepts. Denny used a variety of IB past papers which I particularly enjoyed working with. Moreover, we worked on a software that was very convenient and easy to manipulate allowing smooth communication even though we lived in different countries. *******


******* Before stating tutoring lessons with Denny, I was only just passing the course with a 4, but by the start of the next school year I was getting 6s and 7s! Over the past two years Denny has worked with me not only to improve my mathematical skills but also my confidence. We began with doing some simple example questions so that he could help me properly understand the mathematical theory and concept. Then Denny would advise and demonstrate different methods to solve the problem to present a mathematical perspective that was different to that of my school teacher. The practice boosted my confidence immensely, as Denny helped me understand that there is normally never only one way to solve a problem, and even if I think the question is very hard, there is always a simpler way to view it. * As a result, when it was time to practice IB past paper questions, working through the questions with Denny not only became easier, but also enjoyable! In addition, I saw a very big improvement in my grades. *******


*******Although IB exams were cancelled this year, Denny helped me end the year on a high note with a 5 in trimester 2 and a 7 in trimester 3 as the overall grades. Denny also gave me the help and tips necessary to achieve a 6 in my Math HL IA.* Overall, with Denny’s tutoring, I have reached new levels of math confidence. Denny’s use of past papers as a source of conceptual understanding is another aspect of his teaching that I thought was incredibly important. Since students such as myself at times feel confident with the concepts at first, past papers serve as tools that can really provide students with an accurate representation of their preparedness. I also think that his patience when allowing me to approach a problem is stellar as well. He would never give me the answer straight away, but more so led me through the problem and the concepts needed to solve it. *******


*******Once Denny began teaching me, my score improved to a 7 average. Not only did this enabled me to achieve the academic honor award at school, but it also opened up the opportunity for me to study Chemical Engineering at UC Berkeley. I want to really thank you for the help and knowledge you have offered me. Your approach to IB Maths was efficient and effectual. I was able to discern the different question types in each chapter and sharpen my mathematical skills. *******


*******I got a 6 in Math HL and 40 points overall. * I will be attending Cornell University for the next four years and I am really happy to say that you helped make that happen! Thank you so much for all your help and support throughout your lessons! I know that even though I wasn’t able to do the exam, your helpful insights and math tricks will continue to help me excel in my future studies, especially in engineering. Your advice really helped me reinforce what was covered in class to the extent that I have no hesitation in solving IB problems. *******


*******Recommended by my friend, I have been taking tutoring lessons with Denny for s Ever since I’ve taken the lessons, I made a major improvement – from scoring a C on my finals in my junior year to A* on every test and a 6 on my IB final exam. I was nearly able to get a 7 on my IB final exam, with only a tiny margin below the grade boundary. Denny was extremely helpful and responsible along the way. He would spend extra time answering my homework questions and make his own revision sheets to help me grow. Not only he patiently writes down standard procedures during our private lessons to build up my logical thinking skills, but also go over tests that I did at school to eliminate my weakness. Besides, the effectively used technology a software which allowed us to write on the same screen across counties – to facilitate my learning process. I would say, without his help I could never get such a high score on my IB Finals. *******


*******I am confident that enlisting the tutoring aid was one of the best decisions I made throughout the IB, and it was that which enabled me to receive a strong 7 from the IB final exams. With the aid of an iPad and a working internet connection, I was able to schedule meetings with Denny conveniently at any time and any place (even when travelling on holidays). His style is very structured, categorizing the syllabus into different sections which simplified it for me significantly and made it less overwhelming. Most importantly, as a student who constantly doubted her math abilities, the reassuring words and confidence I got from him was added boost that really needed when taking the exams. With his guidance and assistance, I found the preparations for IB final exams extremely enjoyable and stressfree. Additionally, I got eh confidence I needed to apply for a mathematics degree in a top university and entered successfully. *******


*******During the first term I was achieving an overall 4 as a predicted grade and felt that many topics were very challenging. After having lessons with Denny roughly every other week during my last term up until my final exams, I ended up scoring a grade 6 in my mathematics course. Denny provided me with a good understanding of the different types of problems that were likely to appear on my exam and very clearly explained the logical methods of solving these problems. I found it very helpful that Denny always had pastpaper problems ready to demonstrate examples and could easily target the areas that I struggled with most with questions that challenged me. After each lesson, Denny sent me screenshots of all the work that we had covered, which was very helpful because then I could fully pay attention to problemsolving during the lessons since I knew that I could go back and review Denny’s notes afterward when studying in my own time. *******


*******Denny helped me with option calculus, it was effective and methodological. He effectively covered the whole syllabus in just a few lessons and help me go from a 3 to a 6. *******


*******With his help, I have tasted the fulfilment of solving difficult questions which have strengthened my confidence in math. From a 3 in DP1 to a 5 in the IB final exam, I would attribute most of my improvement on them, Without, I would probably fail the test and would never think about pursuing a career in econometrics. *******


*******Just letting you know we received Alec's final grade  his grade went from 3 to 5 in math. I can't thank you enough for your tutoring of Alec. Actually 4 out of his 6 classes went up in marks and I feel it is partially due to his increased confidence in math. I have passed your details on to another family. *******


*******I have finished math with a 6 which I am very happy about. You have played such a big role so thank you so much for all your help and dedication!! I really appreciate it. *******


******* I take great pleasure recommending Denny, who teaches you not only the Mathematical theory but the way in which to approach questions logically, irrespective of their apparent difficulty at first glance. Such cannot be gained from simple textbooks or past paper practice and is a valuable asset for mocks and final exams. * I could always count on Denny to provide me with additional resources and was pleased to see that he would take time after our lessons to help me with additional questions that I would pose him when in doubt.* Denny is undoubtedly one of the most professional tutors for IB Mathematics and has knowledge far beyond the course which allows him to explain all concepts with ease and clarity. *******

******* Before stating tutoring lessons with Denny, I was only just passing the course with a 4, but by the start of the next school year I was getting 6s and 7s! Over the past two years Denny has worked with me not only to improve my mathematical skills but also my confidence. We began with doing some simple example questions so that he could help me properly understand the mathematical theory and concept. Then Denny would advise and demonstrate different methods to solve the problem to present a mathematical perspective that was different to that of my school teacher. The practice boosted my confidence immensely, as Denny helped me understand that there is normally never only one way to solve a problem, and even if I think the question is very hard, there is always a simpler way to view it. * As a result, when it was time to practice IB past paper questions, working through the questions with Denny not only became easier, but also enjoyable! In addition, I saw a very big improvement in my grades. *******


*******Although IB exams were cancelled this year, Denny helped me end the year on a high note with a 5 in trimester 2 and a 7 in trimester 3 as the overall grades. Denny also gave me the help and tips necessary to achieve a 6 in my Math HL IA.* Overall, with Denny’s tutoring, I have reached new levels of math confidence. Denny’s use of past papers as a source of conceptual understanding is another aspect of his teaching that I thought was incredibly important. Since students such as myself at times feel confident with the concepts at first, past papers serve as tools that can really provide students with an accurate representation of their preparedness. I also think that his patience when allowing me to approach a problem is stellar as well. He would never give me the answer straight away, but more so led me through the problem and the concepts needed to solve it. *******


*******Once Denny began teaching me, my score improved to a 7 average. Not only did this enabled me to achieve the academic honor award at school, but it also opened up the opportunity for me to study Chemical Engineering at UC Berkeley. I want to really thank you for the help and knowledge you have offered me. Your approach to IB Maths was efficient and effectual. I was able to discern the different question types in each chapter and sharpen my mathematical skills. *******


*******I got a 6 in Math HL and 40 points overall. * I will be attending Cornell University for the next four years and I am really happy to say that you helped make that happen! Thank you so much for all your help and support throughout your lessons! I know that even though I wasn’t able to do the exam, your helpful insights and math tricks will continue to help me excel in my future studies, especially in engineering. Your advice really helped me reinforce what was covered in class to the extent that I have no hesitation in solving IB problems. *******


*******Recommended by my friend, I have been taking tutoring lessons with Denny for s Ever since I’ve taken the lessons, I made a major improvement – from scoring a C on my finals in my junior year to A* on every test and a 6 on my IB final exam. I was nearly able to get a 7 on my IB final exam, with only a tiny margin below the grade boundary. Denny was extremely helpful and responsible along the way. He would spend extra time answering my homework questions and make his own revision sheets to help me grow. Not only he patiently writes down standard procedures during our private lessons to build up my logical thinking skills, but also go over tests that I did at school to eliminate my weakness. Besides, the effectively used technology a software which allowed us to write on the same screen across counties – to facilitate my learning process. I would say, without his help I could never get such a high score on my IB Finals. *******


*******I am confident that enlisting the tutoring aid was one of the best decisions I made throughout the IB, and it was that which enabled me to receive a strong 7 from the IB final exams. With the aid of an iPad and a working internet connection, I was able to schedule meetings with Denny conveniently at any time and any place (even when travelling on holidays). His style is very structured, categorizing the syllabus into different sections which simplified it for me significantly and made it less overwhelming. Most importantly, as a student who constantly doubted her math abilities, the reassuring words and confidence I got from him was added boost that really needed when taking the exams. With his guidance and assistance, I found the preparations for IB final exams extremely enjoyable and stressfree. Additionally, I got eh confidence I needed to apply for a mathematics degree in a top university and entered successfully. *******


*******During the first term I was achieving an overall 4 as a predicted grade and felt that many topics were very challenging. After having lessons with Denny roughly every other week during my last term up until my final exams, I ended up scoring a grade 6 in my mathematics course. Denny provided me with a good understanding of the different types of problems that were likely to appear on my exam and very clearly explained the logical methods of solving these problems. I found it very helpful that Denny always had pastpaper problems ready to demonstrate examples and could easily target the areas that I struggled with most with questions that challenged me. After each lesson, Denny sent me screenshots of all the work that we had covered, which was very helpful because then I could fully pay attention to problemsolving during the lessons since I knew that I could go back and review Denny’s notes afterward when studying in my own time. *******


*******Denny helped me with option calculus, it was effective and methodological. He effectively covered the whole syllabus in just a few lessons and help me go from a 3 to a 6. *******


*******With his help, I have tasted the fulfilment of solving difficult questions which have strengthened my confidence in math. From a 3 in DP1 to a 5 in the IB final exam, I would attribute most of my improvement on them, Without, I would probably fail the test and would never think about pursuing a career in econometrics. *******


*******Just letting you know we received Alec's final grade  his grade went from 3 to 5 in math. I can't thank you enough for your tutoring of Alec. Actually 4 out of his 6 classes went up in marks and I feel it is partially due to his increased confidence in math. I have passed your details on to another family. *******


*******I have finished math with a 6 which I am very happy about. You have played such a big role so thank you so much for all your help and dedication!! I really appreciate it. *******


******* I take great pleasure recommending Denny, who teaches you not only the Mathematical theory but the way in which to approach questions logically, irrespective of their apparent difficulty at first glance. Such cannot be gained from simple textbooks or past paper practice and is a valuable asset for mocks and final exams. * I could always count on Denny to provide me with additional resources and was pleased to see that he would take time after our lessons to help me with additional questions that I would pose him when in doubt.* Denny is undoubtedly one of the most professional tutors for IB Mathematics and has knowledge far beyond the course which allows him to explain all concepts with ease and clarity. *******


Hi, my name is Denny. I am a fulltime math tutor and I focus on teaching IB Maths. I have indepth understandings of all the topics in IB math syllabus and exams. I have collected and analyzed all the IB maths past papers in the past 10 years, therefore, I can precisely help my students revise all the topics that definitely will be tested in their chapter tests and IB final exams. I have developed efficient teaching methods to help maximize students’ efforts and achieve their academic goals. I will teach my students effective learning skills so that they grasp key concepts much faster and I will teach them useful problemsolving techniques so that they can solve IB exam questions much easier. I have successfully helped hundreds of students improve grades and get accepted into their dream universities.

My productive teaching methodology and strategy are built on thousands of hours of online tutoring experience and proven results of improvements from hundreds of students. I am proud of my services which are highly recognized and recommended by my students and their parents.
 Some of recent testimonials:  
*******After Denny started tutoring me, my grades went from 4s to 6s and 7s and I scored a 7 on my final IB exams. Denny taught me all the topics, starting with basic theories and formulas. He made sure I understood the easy problems first before moving on to more complex ones. What really helped me was that Denny showed me multiple ways to solve a problem; it broadened my understanding of the topic as well as my critical thinking. I became more flexible in different questions, really applying my knowledge rather than solving a problem by a learned/memorized method. *******


*******This is coming from an IB student who failed to submit a single piece of homework in maths over my 2 DP years, and skipped 20% of my IB classes. I booked him every day for a week before my final exams and my grade went from a 4 to 7. The results speak for themselves, I cannot recommend him enough. His teaching style is phenomenal if you don't like to waste time and get shit done; he cuts out all the useless/filler crap regular teachers/other tutors often make you put up with and gets right down to the meat. He is just really good at his job. Not only does he know the material inside and out, he has made sure to fully understand the IB criterion and marking styles to make sure that he not only teaches you the math itself, but exactly how to word your answers to maximize your marks and teaches you the question formats you'll face on exams. Study smarter, not harder. *******


*******I got a 44 with a high 7 in mathematics AA HL. I am so thankful that you have been a tutor for me in this process. You have been a source of motivation for me in the process, and you have helped me clear so many doubts. You help the student discover their weak points, and give detailed solutions and explanations for complex questions Thank you very much. *******


*******Before my lessons with Denny, I was getting constant 3s and 4s at school and was having issues with the way my teacher taught me the syllabus. I am extremely grateful to have had such a delicate and skillful tutor who enabled me to reach a score of 6 at my final exams. I would have never done so well without him. When working with Denny, he would not only teach me the Mathematical concepts but he would also show me the way in which to approach each question. Throughout the year Denny and I deeply reviewed each topic of the syllabus to strengthen my understanding of several concepts. Denny used a variety of IB past papers which I particularly enjoyed working with.

He would spend extra time answering my homework questions and make his own revision sheets to help me grow. Not only he patiently writes down standard procedures during our private lessons to build up my logical thinking skills, but also go over tests that I did at school to eliminate my weakness. Besides, the effectively used technology a software which allowed us to write on the same screen across counties – to facilitate my learning process. I would say, without his help I could never get such a high score on my IB Finals. *******


*******I am confident that enlisting the tutoring aid was one of the best decisions I made throughout the IB, and it was that which enabled me to receive a strong 7 from the IB final exams. With the aid of an iPad and a working internet connection, I was able to schedule meetings with Denny conveniently at any time and any place (even when travelling on holidays). His style is very structured, categorizing the syllabus into different sections which simplified it for me significantly and made it less overwhelming. Most importantly, as a student who constantly doubted her math abilities, the reassuring words and confidence I got from him was added boost that really needed when taking the exams. With his guidance and assistance, I found the preparations for IB final exams extremely enjoyable and stressfree. Additionally, I got eh confidence I needed to apply for a mathematics degree in a top university and entered successfully. *******


*******During the first term I was achieving an overall 4 as a predicted grade and felt that many topics were very challenging. After having lessons with Denny roughly every other week during my last term up until my final exams, I ended up scoring a grade 6 in my mathematics course. Denny provided me with a good understanding of the different types of problems that were likely to appear on my exam and very clearly explained the logical methods of solving these problems. I found it very helpful that Denny always had pastpaper problems ready to demonstrate examples and could easily target the areas that I struggled with most with questions that challenged me. After each lesson, Denny sent me screenshots of all the work that we had covered, which was very helpful because then I could fully pay attention to problemsolving during the lessons since I knew that I could go back and review Denny’s notes afterward when studying in my own time. *******


*******Denny helped me with option calculus, it was effective and methodological. He effectively covered the whole syllabus in just a few lessons and help me go from a 3 to a 6. *******


*******With his help, I have tasted the fulfilment of solving difficult questions which have strengthened my confidence in math. From a 3 in DP1 to a 5 in the IB final exam, I would attribute most of my improvement on them, Without, I would probably fail the test and would never think about pursuing a career in econometrics. *******


*******Just letting you know we received Alec's final grade  his grade went from 3 to 5 in math. I can't thank you enough for your tutoring of Alec. Actually 4 out of his 6 classes went up in marks and I feel it is partially due to his increased confidence in math. I have passed your details on to another family. *******


*******I have finished math with a 6 which I am very happy about. You have played such a big role so thank you so much for all your help and dedication!! I really appreciate it. *******


******* I take great pleasure recommending Denny, who teaches you not only the Mathematical theory but the way in which to approach questions logically, irrespective of their apparent difficulty at first glance. Such cannot be gained from simple textbooks or past paper practice and is a valuable asset for mocks and final exams. * I could always count on Denny to provide me with additional resources and was pleased to see that he would take time after our lessons to help me with additional questions that I would pose him when in doubt.* Denny is undoubtedly one of the most professional tutors for IB Mathematics and has knowledge far beyond the course which allows him to explain all concepts with ease and clarity. *******

French teacher  Passing the DELF or DALF (French diploma)  Private preparation sessions  [IN LINE]
I am Fawzi, a French language teacher. I have been giving private lessons online since 2012.
I offer specific sessions to meet your needs and objectives to pass your DELF (Diploma in French Language Studies) or DALF (Advanced Diploma in French Language), including the TCF (French Knowledge Test). I accompany many interested parties of different nationalities thanks to online courses since 2012; for me, helping enthusiasts to practice the French language is a very good experience because I understand that success is a key objective in the life of ambitious people.
I speak Arabic, French, Spanish, a little English and a little Turkish. I explain my lessons in French, Arabic or Spanish, depending on your choice. And at the end of each session, I give lessons with exercises to do as homework to examine your shortcomings and monitor your progress.

Here are some things to know about the DELF and DALF:
The DELF (Diploma of Studies in French Language) and the DALF (Advanced Diploma in French Language) are two official and quality diplomas. They are harmonized on the levels of the Common European Framework of Reference for Languages. They include the following six levels, in ascending order: A1, A2, B1, B2, C1, C2. These two diplomas are suitable for all ages and all audiences.
In addition, the DELF B2, and increasingly the DALF C1, allow students to enter French, European or Frenchspeaking universities, and certain Grandes Ecoles.

Will you have DELF or DALF exams to pass? Do you need to follow specific sessions with me to improve your level?
Don't hesitate to book your sessions so that we can start the preparation.
I am available !

Excellence Math, Physics, Chemistry  19 average  New program 2022
Give your child the future he deserves.
Graduated from Arts et Métiers ParisTech / 20/20 in mathematics at the Bac / preparatory class / Private teacher for 10 years
Do you want to significantly increase your child's mathematical average?
Do you want it to integrate a selective course?
Do you want it to become autonomous?
For 5 years, I have helped more than 30 French students in difficulty from middle school (sixth, fifth, fourth, third) and high school (second, first, final) to achieve their goals (good average, patent, bac, PREPA) and to regain selfconfidence.
My method in 3 points:
 short term,
significantly increase the average by assimilating the course and preparing for the next tests (assimilating the course, writing sheets, training in standard exercises, anticipating the teacher's expectations and test questions, having writing methods)
 medium term,
integrate reasoning and working methods (learn to work regularly in this order: assimilation, training exercise, test preparation and test analysis passes)
 longterm,
set a goal, build the steps to achieve this goal, become aware of the SIMPLICITY of math, have confidence in your abilities, unlock your potential)
The formula: one or two sessions of 1h30/2h per week for the assimilation of the course and to prepare for the test.
 Classes on Google Meet
 Virtual whiteboard to assimilate faster
 Library of 10 books online
 More than 1000 exos online

🚀EVERY CHILD IS A MATHS GENIUS  British Tutor 🇬🇧
.. [British Maths Tutor] ...
When I was a young child, I believed I was not a mathematical person.
It wasn't until I met an amazing teacher at age 15 that I discovered my mathematical genius and my life was changed forever.
I'm eternally grateful to that teacher.
My teacher knew that selfimage and selfbelief is the key to unlock your child's mathematical abilities.
Everyone is good at maths, but we all have different styles of thinking.
Bad teachers teach every child the same way.
My job is find your child's style of mathematics and allow him to discover that for himself.
When he discovers that, he will begin to enjoy the beauty and power of mathematics
...and then you will see as the grades begin to soar.
👉Click the blue "Contact Oliver" button above and lets discuss how we can unlock your child's mathematical talents! 😊

Private physics and mathematics lessons for all levels, by a physicist engineer experienced in teaching
College, high school, or bachelor, I give courses adapted to the student. Help with homework, preparation for exams, practice exercises.
I myself was a student asking a lot of questions and I encourage you to ask as many questions as possible to clarify all the gray areas and leave nothing to chance, and thus promote exam success.
Academic success is not a matter of innate aptitude but simply of noticing your weak points and working on them. I know how to notice them in the student by often asking him questions about the meaning of the exercise and each line of calculation. I encourage students to develop their intuition so they can easily adapt to any problem on exam day.

Private lessons and tips in mathematics and physicschemistry
Hello,
I am a student in double license computermathematics at the university paris 13.
I can give tutoring in mathematics so that in physics and chemistry, the main advantage of my courses is that they contain tips that improve the student's response to an exercise, a very good course that aims the essentials without forgetting the important details, and a followup of the evolution of the student through the tests of progression and exercises since the exercises of application until the starry exercises.
Apart from my good teaching approach, I have great skills in mathematics and physics chemistry besides I am the first dz my class in mathematics in double license.
Through my private lessons I want not only to transmit my knowledge, but also the good methods and reflexes before tests or exercises.
Cordially.
Sabrina
Specific Math course to overcome your difficulties, review your lessons and prepare your exams.
Graduated in engineering, I teach maths (primary, college and high school) 8 years of experience in the field.
We all had difficulties to solve in maths but at two we learn better, my important points to transmit the knowledge:
* be listening to the difficulties found by the students.
* Explain to them how to solve them with simple and effective methods.
* give them methodological advice concerning the management of time and the organization of work.
* Being dynamic, smiling and having a source of motivation in itself always comforts students and encourages them to give the best of themselves.
