A math, physics or chemistry class as explained by a friend? Nothing more pleasant! I am a graduate of an engineering school, and I would be happy to teach science subjects. I have regularly been able to give rehearsal lessons and see more than promising results by proposing the following working method: - Get to know each other (because trust in teaching is important!) - Briefly review the theory (to understand the blocking points) -Train on a typical exercise (to unlock these points and thus explore the student's full potential!)
