Chemistry from VMBO to VWO (also 2-language education) and International school. Lessons depend on the question with which the student/student is involved. Mathematics depends on the problem. We define the objective in advance and the feasibility is tested. 100% commitment of the student is appreciated. I have taught at the Inholland University of Applied Sciences in Amsterdam (Chemistry). Do homework and give tutoring. In addition, I am currently supervising students from an International School.
