As a physics and chemistry teacher, I offer my services to students of different levels in several establishments. I also offer you my experience: - CPGE (MPSI, PCSI, MP, PC, PSI and TSI): Physics and chemistry in preparatory classes for the grandes écoles. - IMT LILLE DOUAI course: Geometric optics, electronics and electrical and mechanical oscillators - EPFL general physics: mechanics of the material point, mechanics of the solid and electromagnetism. I will modulate my method according to your needs and expectations (recovery of basic concepts or more intensive work to push the concepts further).
