During the first part of the course I propose to come back to the notions not understood in order to assess the potential gaps, then we will continue on different exercises with increasing difficulty. At the end of each course, I will send the student all the exercises with their corrections as well as a summary course sheet. In scientific subjects, the key to success is practice, so if the student wishes, I can send him additional work that he can send back to me by email outside of class hours.
