Student entering second year at Polytech Lyon, engineering school, I wish to give courses in mathematics, science and English mainly to students of middle school, high school or freshman in preparatory course, or engineering school. I offer exercises corresponding to the programs and level of the student, a help with the preparation of exams or a homework help that it must realize at home. The goal is not to overload the student, but only to make him acquire an effective working method and a good knowledge of the important concepts, to be able to solve problems alone, with the help of the work carried out.
