Former pre-school students at the Grandes Ecoles Scientifique at Lycée Condorcet in Paris: MPSI then PSI*, admitted to ENS and Centrale Lille.

The idea being to (re) give confidence to the student and that he can appreciate these subjects. Having already taught, I am attentive and pedagogue. My methodology is as follows: - Revision of the notions that you did not understand during the lessons via examples - The student can ask me all the questions he wants, about the course or an exercise - Training exercises / deepening - Preparation of future controls
