Mathematics is often misunderstood by the general public, but it is of capital importance and it is important to master at least the basics. My course is intended for students who would like to upgrade or get ahead in this subject. Curiosity is welcome! I am currently doing a Master's in Mathematical Sciences with an in-depth focus at the ULB. I hold a Bachelor's degree in Mathematics from the University of Strasbourg and I am a former student in Preparatory Classes for the Grandes Ecoles (Maths-Physics mention) in France. I offer courses made according to the needs (or desires) of the students. This can be adapted for primary, secondary and university students (up to Bachelor Block 2).
