I offer private lessons on high school / CPGE level chapters PCSI or PC in mathematics and physics. Tell me the topic that interests you, and we will see together how to achieve your goal: overcome difficulties, improve or seek perfection! I will be available even after school hours for questions if needed! The method I use depends on the student, and as far as homework or questions are concerned, it's to be seen after discussion at the start of the first class. In any case, I invested in a graphics tablet, which allows me to do webcam lessons as if I were there.
