Marks and exams
The French marking system is based on a numbered scale from 0 to 20 (with 20 being the highest). An average of 10/20 is usually necessary to pass a course. 12 is usually a satisfying mark, and few students manage to maintain a yearly average of 16 (considered a very good mark) or above. Validation requirements of courses depend on your curriculum, school or institute.
Depending on your department, examination will be organised differently: either as continuous assessment (exams and tests are organised all year or semester long), or with two examination sessions, one at the end of each semester.
