We have all benefited at least once from an individual explanation that has changed our outlook on a subject. The serenity of a lively and fun training is ideal for developing knowledge but especially the desire to know. The main quality of a teacher must be his human dimension based on listening, trust and commitment throughout the year. I was able to acquire solid knowledge in mathematics during my preparatory class at the Henri IV high school and the master's degree in fundamental mathematics which I majored in. Helping a student progress and seeing their parents satisfied with their level motivates me even more to provide a good quality course and to achieve the objectives set. I am happy to pass on this modest amount of knowledge to all students each time and I quickly establish a working atmosphere conducive to progress. Preparing for the baccalaureate and competitive exams are stimulating for me... And as Socrates said: "All I know is that I know nothing."
