My classes are aimed at middle and high school students and students preparing to enter a science CPGE (Preparatory School for Primary Schools). These classes can be both academic support and a deeper dive into certain concepts. In my classes, I often proceed in two parts: - on the one hand I provide lesson reminders on the concepts studied in class (to master the basics); - on the other hand I give exercises during which I guide the student, I give them advice on calculations and methodology.
