Following preparatory classes in mathematics and physics, graduate of the Ecole Normale Supérieure and a Doctorate in science, I offer courses at all levels in mathematics and other sciences. A method based on the exchange with the student and his questions, which adapts above all to his needs. Available for all levels and all goals. The work of the theoretical bases, the specific deepening, the work of understanding and putting it into practice, the preparation of exams such as the baccalaureate or others. As shown by my particularly successful academic background, I have a good understanding of mathematical concepts and academic expectations to achieve one's goals. I have already learned, through certain teaching experiences, particularly at university and during private lessons, how to effectively transmit knowledge useful for success in science.
