Having gone through two years of preparatory Maths sup Maths spé then by an engineering school of the CentralSupelec competition (the Institute of Theoretical and Applied Optics) and currently working at the Astrophysics Laboratory of Marseille, I propose to give courses of Mathematics at home to students in college or high school. Possibility to correct and annotate exercises throughout the week in addition to face-to-face lessons at the student's request (very useful for practicing good writing).
