Mastery of languages, whether French or English, determines success in all disciplines and all careers. After evaluating your level, with patience and gentleness, we will go over the points and questions that remain obscure, then play exercises allowing you to deepen your understanding of these two languages.

With patience and gentleness, we will devote ourselves to the revision of the aspects of physics and chemistry that are obscure and to exercises, of progressive difficulty, in these two subjects.
