Chemical Calculations for AS & A2 Chemistry (All Exam Boards)
course price icon
من 128.83 SAR
arrow icon
Calculations are a necessary and fundamental element (pun intended) of Advanced and University Level Chemistry and it is best to be well-acquainted with the requisite formulae and equations prior to starting your AS studies as it can become rather messy! It also seems to be the topic most students find challenging.

All UK Exam Boards examine an almost identical application of the calculations required to meet the syllabuses. The calculations demonstrated in A2 are an extension to what is established during AS; the content may be more comprehensive in A2 but the general application is not dissimilar.

To obtain the most from this class students should be familiar with CGP’s Complete Course (relative to their exam board, e.g. AQA, OCR, ... ) [AS or A2 edition]- in particular, the chapters outlining chemical calculations.
معلومات إضافية
A scientific calculator and periodic table of chemical elements are needed.

Physics and chemistry are the gateway to understanding all sciences, as a science student you will need to be able to sort through the many complex features to become a true student scientist with a critical and curious mind. That's why I designed this course to help students prepare for their exams and the next school year to fill in the gaps they have in math and science.
I would like to inform you that I am a young researcher and I can also help you to acquire basic knowledge of Microsoft Office and other essential software for your career.

Struggling with math, physics, or chemistry? You're not alone — these subjects are hard, and classroom explanations are rarely enough.
I offer personalized tutoring for middle school, high school, and early university students following the French Mission curriculum, the Moroccan national curriculum, or the international baccalaureate.
Topics covered:

Mathematics: algebra, geometry, calculus, trigonometry, probability
Physics: mechanics, electricity, optics, thermodynamics
Chemistry: organic, inorganic, stoichiometry, reactions

My approach:
I don't re-explain the textbook — I identify exactly where your understanding breaks down and fix it from there. Each session is built around your specific difficulties, not a preset program.
I completed CPGE (Classes Préparatoires aux Grandes Écoles) in Mathematics and Physics before graduating as a State Engineer — I know these subjects at an advanced level and I know where students typically get lost.
Individual and small group sessions available. Online (worldwide) in French, Arabic, or English.

As a high school teacher with a Master's degree in mathematics and 11 years of experience in face-to-face and online teaching, I offer qualified and competent private lessons for all levels, ranging from high school TC-SC 1Bac Sc-SM to Bac PC-SM, through middle school and classes of 2nd and 1st general Terminale specialty of the French system, as well as for levels 5th, 4th and 3rd of middle school, and preparation for the baccalaureate and competitions .

I emphasize the method, with a rigorous, personalized approach adapted to the rhythm of each student in order to help him progress while regaining confidence in himself. My job is to identify each student's shortcomings, organize their time and manage their priorities.

I obtained a success rate of 100% for my final year baccalaureate students, 75% of whom obtained a good or very good mention. Some of them have joined the biggest business and engineering schools, as well as prestigious preparatory courses.

I offer online or face-to-face lessons.

As a teaching professional, I have always enjoyed sharing my knowledge. My goal is to provide quality education. I am aware that some topics may seem complex, but often this is simply the result of an inadequate explanation by the teacher. With me, you will discover a real interest in the material!

We strive together to achieve academic excellence, overcoming the shortcomings and difficulties encountered by your child. Studies will become a pleasant experience for him. In addition to the courses, I can also help with school orientation, identifying their preferences and highlighting the advantages and benefits of a fulfilling educational ambition.

The sessions generally take place according to the following stages:

1️⃣ The first sessions are devoted to the assessment of the student's level in order to detect existing gaps.

2️⃣ Next, we create a personalized plan to address these gaps, including the number of hours of work needed, specific areas to focus on, and appropriate training and development exercises.

3️⃣ We stay in constant contact with the student's class teacher, to keep up to date with the latest requirements and ensure a consistent approach.

4️⃣ Subsequently, I provide exams similar to those that are likely to be asked in class, to prepare the student effectively.

5️⃣ Upon request, I write a regular report, usually monthly, to keep parents informed of their child's progress throughout their course.

I adapt my methodology according to the specific needs of each student, thus offering them a personalized and adapted work approach.

In addition, I offer crash courses for students preparing for the start of the school year, allowing them to start the year well prepared, with a solid lead on the school curriculum.

If you have any questions, do not hesitate to contact me. I will be happy to help you.

Hello students! Do you find it difficult to learn science subjects, especially chemistry? This may be because chemistry contains some difficult or complex concepts or terms. If you are one of these, do not worry!! Hello and welcome to you, my students, in the right place to solve this problem through simplifying science lessons, especially chemistry. Through these lessons, we will learn together how to deal with difficult-to-understand matters and terms, because I have extensive experience extending to more than 15 years in conveying complex concepts in a clear, easy and simple way. My goal is to make science and chemistry in general and organic chemistry in particular wonderful and understandable for everyone. As a dedicated teacher, I create an interactive and stimulating learning environment for my students using the latest methods. I am ready to share my passion and guide each student towards excellence and success in the field of science and organic chemistry and in studies in general, as I work as a student advisor in an international institution. In addition, I have excellent communication and presentation skills and am patient and calm when teaching. In addition, I constantly follow up on my students' progress and regularly evaluate their understanding through continuous solution of objective questions, as I care more about understanding than memorization. On the other hand, I also maintain good follow-up with parents. My teaching approach is directed towards achieving the highest results, with a focus on helping students understand and master information.

For university students or master's and doctoral students, I teach the course of natural product chemistry or phytochemistry. In this course, we will learn about the methods of extracting, separating and identifying the chemical form of active chemical compounds (biologically active secondary compounds) from natural sources, such as medicinal and aromatic plants. We will also discuss what is known as chromatography, spectroscopy devices, spectroscopy, mass spectrometry and magnetic resonance analysis. In addition to knowing some important applications of these active materials in various fields, such as the pharmaceutical industry, agriculture, etc. We will also learn the practical methods that are carried out in the laboratory to conduct toxicity, antioxidant and diabetes analyses, etc.

Finally, "for those interested in scientific research" there is a course dedicated to knowing what scientific research is, how to choose a research point, how to write scientific research and how to find the appropriate journal for publication and everything related to this topic.

Experience: About 20 years of practical experience in the field of chemistry, medicinal and aromatic plants and pharmacy with parallel training and private lessons for chemistry curricula.

With my qualifications and experiences, as I hold a master's degree and a doctorate in organic chemistry (chemistry of natural products), in addition to other postgraduate certificates and a doctoral scholarship in pharmaceutical sciences in Belgium from the Erasmus Mundus organization affiliated with the European Union.
