Sample Space (S): The set of all possible outcomes of an experiment.

Event (E): A specific outcome or combination of outcomes within the sample space.

Probability (P): A measure of the likelihood of an event occurring, ranging from 0 to 1.

Probability of an Event (P(E)): Calculated as (Number of Favorable Outcomes) / (Total Number of Outcomes).

Complement of an Event (E'): The set of outcomes not in event E, with P(E') = 1 - P(E).

Mutually Exclusive Events: Events that cannot occur simultaneously, with P(E or F) = P(E) + P(F).

Independent Events: Events whose occurrence doesn't affect each other, with P(E and F) = P(E) * P(F).

Conditional Probability: Probability of an event given that another event has occurred, calculated as P(E|F) = P(E and F) / P(F).

These concepts form the foundation of probability theory, which is essential for understanding and quantifying uncertainty and randomness.

I am honored to be a university professor specialized in teaching statistics, mathematics, operations research, and economics. Thanks to my extensive experience, which extended for 15 years, I became a professional in monitoring students’ level and contributing to their academic success and achieving their cognitive goals.
I truly find true happiness in my work as a university professor by guiding and helping students in achieving their academic realization and raising their level of scientific awareness. Therefore, I have a strong belief in the importance of this noble mission in the field of education.

Typically, sessions go like this:

1️⃣ The first sessions focus mainly on assessing the student’s level to determine the areas that need development.

2️⃣ Next, we prepare a plan to fill the gaps, including determining the number of hours needed, the materials to focus on, and providing a set of training and improvement exercises.

3️⃣ We are keen to constantly review the student’s curriculum to stay informed of the latest developments and ensure continuous coordination.

4️⃣ Next, we provide exams similar to those that could be asked in class.

5️⃣ Finally, we prepare a monthly report upon request to notify parents of the student’s progress and improvement points.

I am a qualified and experienced mathematics tutor. Graduated from the Free University of Brussels in 2011, I started my career by teaching remedial courses in different schools in Brussels. I then specialized in individual academic support by following educational training at the Harvard Graduate School of Education. I have been giving private mathematics lessons daily for over ten years.

The students who follow my private lessons benefit from personalized support. The first session is devoted to an in-depth assessment of the student's mathematical knowledge. The objective is to detect its weak points and understand their origin in order to adapt my courses to its needs. I develop a tailor-made remediation program for each of my students aimed at filling each of their gaps. Over the course of the sessions, the student builds a solid foundation for learning and regains self-confidence. At the same time, I help him acquire a work methodology that allows him to gradually become autonomous in his studies.

I have a thorough knowledge of the mathematics curriculum for middle and high school (from 6th to 12th grade). I am also qualified to support students in preparing for international exams such as the SAT, the OMPT, and the International Baccalaureate (IB) in all its variations: Analysis and Approaches (AA SL/HL) and Applications and Interpretation (AI SL/HL).

Throughout my years of training, I studied and developed numerous techniques that facilitate learning mathematics. The strength of my teaching approach lies in my ability to explain, in simple terms, anything a student finds complicated. I am passionate about this profession because it offers me the opportunity to guide struggling students toward success. It is a true pleasure to see them progress and rediscover their connection with the fascinating world of mathematics.

I offer private tutoring in Paris (at the student's home) or remotely (online). My online lessons take place on an interactive whiteboard. This whiteboard is specifically designed to facilitate student/teacher interaction online. Thanks to this teaching tool, my online lessons are just as effective as in-person lessons. The student only needs an internet connection and a computer, tablet, or smartphone to participate.

Passionate & empathetic teacher. I have a Master's in Physics with honors from the University of Leicester (which was featured at the time as a top 5 Physics university in the UK by The Guardian) and a - french - European School diploma in which I achieved 90% in Physics and 85% in Maths.

Helping others understand difficult topics and skills is something that I am very passionate about as an empathetic person. I have experience teaching Physics and Maths to kids from unprivileged backgrounds at the homework school in Saint-Gilles (CASG du Service Social Juif asbl) as well as 5 years of private teaching.

In my classes, I aim to:

- help students achieve better grades in exams/tests in all branches of Physics & Maths
- clearly explain and break down topics
- give context and or example applications of topics (to improve understanding and memorization)
- help with ADHD & other learning disabilities
- give practical advice for university applications (eg. UCAS in the UK) and discuss the exciting Physics research/work and projects you can work on later in life.

Physics has a plethora of useful and fascinating applications, from the detection of Gravitational Waves and Gamma-Ray Bursts to the development of novel Medical Imaging techniques and Nano-technology (eg: smartphones). It is a subject that I am very passionate about and I hope to make use of my years of experience and extensive knowledge to help you understand and love the subject! My lessons will always be tailored to the individual needs of the student, so please do not hesitate to contact me if you have questions!

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.

Enseignante en math, physique, biologie depuis une vingtaine d'années. J'ai une formation d'ingénieur industriel en chimie.
Durant ma carrière, j'ai eu l'occasion de travailler pendant dix ans au sein d'une asbl qui proposait des coups de pouce dans différents branches dont les maths. De cette expérience, j'en retire une adaptation au niveau scolaire de chaque étudiant en utilisant une pédagogie appropriée.
Suivant les demandes, des séances de cours peuvent être précédées de mouvements de brain gym pour faciliter l'apprentissage. L'avantage est qu'une fois acquis ces mouvements peuvent se faire seul à la maison.

Je propose des remises à niveau ou des renforcements des capacités acquises dans l'enseignement secondaire et et dans l'enseignement supérieur.
Dans le cadre de ma pratique et en fonction de la demande, je complète les séances par des exercices complémentaires car "les maths passent par le poignet" comme j'ai l'habitude de dire aux élèves.
Le suivi peut avoir lieu à n'importe quel moment de l'année de manière ponctuelle (pour préparer une évaluation) ou de manière plus étalée.
Les cours particuliers se donnent en présentiel sur Charleroi. Possibilité de cours via caméra les soirées ou les we.
Si vous souhaitez apprendre de nouvelles stratégies d’apprentissage ou reprendre confiance en vous, je vous accompagne dans le cadre d’un plan de soutien à la réussite en associant des outils de coaching. Pour en savoir plus sur le pack, n’hésitez pas à regarder mes autres propositions de cours.

I am a dynamic and demanding teacher who gives private lessons in Physics-Chemistry as well as Mathematics.

I graduated from teaching seven years ago, after a masters in physical sciences with honors, and I teach in college and high school since.
I have also been preparing students for the Baccalaureate Science for many years, all of whom have been awarded very good honors.
I also prepare my students for different exams (Matu, Bac, preparation for EPFL, etc...)

I make sure to rework the basics so that the student can progress quickly. It is important to me that my students acquire a solid foundation of knowledge.
I also give effective work methods that will allow him to progress much more quickly and so he can regain self-confidence.

I can travel to the student's home or also conduct the lesson via Zoom/Google Meet.
