Mathematics and physics lessons for students from primary to college / ecg / business school. I try to adapt to the needs of the student, while putting as much emphasis as possible on practice by solving exercises, which is a crucial point for doing well in science subjects. When it is necessary to explain concepts of the course, I often prefer to base myself on concrete examples which are generally more meaningful than theoretical explanations. I like to prepare lessons in advance; It is therefore preferable as far as possible to provide me with the course material or the exercises in advance so as not to waste time during the lesson.
