Passionate about life and material sciences, I offer biology and chemistry courses for secondary school, college and higher education students. My courses are aimed at all levels: - Regular refresher or support - Preparation for exams (maturity, entrance tests, tests) - In-depth study for curious or advanced students Each session is adapted to the student's profile: we begin by identifying the points to be reinforced, then I offer clear explanations, diagrams, targeted exercises and tips to better understand the fundamental concepts. Thanks to my experience as a laboratory assistant at the Collège de Genève and my replacements in biology and chemistry, I have developed a concrete and caring approach, where understanding the meaning precedes memorization. I emphasize the scientific method, the logic of phenomena and self-confidence, because everyone can progress in science with the right approach.
