Engineer with a double degree from the Ecole des Mines de Saint-Etienne (Major in microelectronics, computer science and new technologies in addition to a research master's degree in industrial engineering and operational research), holder of a bachelor's degree in economics from Paris Sud, currently a consultant and passionate about mathematics, I offer my services of private lessons for the high school level. With over 11 years of experience in private tutoring, I have supported several students in difficulty or improvement. All my students have observed a significant improvement in their results in mathematics throughout the school year and most of them have obtained honors in the baccalaureate. My classes are oriented towards the improvement of the notions of mathematics mainly from secondary school (second, first and final - all sections), I also work with 3rd year students. I provide exam preparation courses (Baccalaureate, patent, competition etc.) which are dedicated to the practice of annals and exercises to prepare for the test. These courses are an opportunity to put yourself in a situation and to approach a maximum of themes to be psychologically confronted with a test format. Internships and courses can relate to all disciplines of mathematics: Derivation, Functions, Complex numbers, geometry, probabilities, Numerical sequences, probabilities .... I have a digital tablet and software that can virtually reproduce the experience of a courtroom. All the student needs is skype or zoom. I also have lesson videos that I can share with you so that you can see the format of a virtual lesson. The course can be recorded by the student if he wishes so in order to revise a posteriori.
