What is something I should never do during the semester ?
Interact with tutors during exercise session when there is something I did not understand in the lecture
Drop by your professor's office at any time, if you have a problem that cannot be solved with your teammates or by a tutor
Take 15 minutes during the evening after each lecture to read calmly the slides at home (e.g before going to sleep)
Work intensively one or two weeks before the exam to be fully prepared for it
