Normalien at ENS Ulm, I am currently following the courses M1 of Mathematics and Geosciences. I propose here Mathematics and Physics courses for students of the following levels: high school (lycée), prépa and the first cycle of university (licence). My role will be to explain the details of your course at school, to help you understand mathematics and physics, and to help you develop skills for solving problems. I would like to give my courses in English. Also possible in French if needed.
