I have been giving math and physics lessons at all levels (secondary, competitive exam preparation, license) for over 10 years now. In parallel with my thesis, I supervised courses mainly in physics as an assistant at the university. I also had many opportunities to help my students in more general science, chemistry and biology courses, or to prepare them for competitive exams for medical or engineering schools. For greater efficiency, I suggest seeing each other for 2 hours at a time. I also find it easier to access the course material beforehand, and to offer personalized exercises for my students afterwards. A discount is offered on video lessons which must be paid in advance. Travel for face-to-face lessons is only counted beyond 10 km/20 min drive. Face-to-face lessons can be paid in cash.
