I have many years of experience in teaching mathematics in private lessons, in 3 languages, 3 countries and in Swiss colleges. My specialty is the middle school program (12 to 16 years old) and preparation for entrance exams to the gymnasium (high school) and vocational schools. I give lessons in person, at home, or online (whatsapp). For independent students, however, I prefer online lessons because I have a lot of travel for my projects between Tunisia and Switzerland.
