Researcher in mathematics applied to finance, I offer support courses to undergraduate students in mathematics and master's degrees in analysis and application. The session takes place as follows: after an individual interview about the student's academic career, a review program is established for the duration of the private lessons. Then, at the start of each session, I remind you of the central concepts of the course and I answer the student's questions related to the courses. The rest of the session will be dedicated to working on the exercises, the difficulty of which will depend on the level of the student as well as their ambitions. Independently of the session, I will give homework assignments that I will correct for whichever student is learning to write on the day of the exam.
