I also give private lessons to college and high school students. I adapt my lessons according to the needs and level of each student. I can follow the school or university program, or go beyond if necessary. My teaching method favors a classic approach: 1) Thorough understanding of the subject and its importance in the field of study or in daily life. 2) Illustration by concrete examples. 3) Realization of practical exercises to properly assimilate and finally master the subject. I consider comprehension and logical reasoning as essential elements. I accompany the student in his progress and encourage him to work outside of class hours if it suits him.
