I am a dynamic and demanding teacher who gives private lessons in Physics-Chemistry as well as Mathematics. I graduated from teaching seven years ago, after a masters in physical sciences with honors, and I teach in college and high school since. I have also been preparing students for the Baccalaureate Science for many years, all of whom have been awarded very good honors. I also prepare my students for different exams (Matu, Bac, preparation for EPFL, etc...) I make sure to rework the basics so that the student can progress quickly. It is important to me that my students acquire a solid foundation of knowledge. I also give effective work methods that will allow him to progress much more quickly and so he can regain self-confidence. I can go to the student's home or also take the course via Skype.

As a math teacher, I offer private lessons in science subjects. My classes are mainly aimed at cycle and college students in Geneva, as well as students from private schools.
