In France, courses are graded on a scale of 20 where 20 is the best result possible (very exceptional in France) and 0 is the worst result possible. 10 or more is generally required for a course or a semester to be validated.
Then for international mobility, grades are translated into the ECTS grading system.
European ECTS grading system
This scale gives the distribution of all students' grades within the class.
Approx. % of successful students achieving the grade
EXCELLENT - Outstanding performance
VERY GOOD - Above the average standard
GOOD - Generally sound work
SATISFACTORY - Fair but significant shortcomings
SUFFICIENT - Performance meets the minimum criteria
Second Chance exams
If a course is not passed (Grade F) after completion of the semester, students can resit a second exam approximately 1 or 2 months after the end of the course. If necessary, you may retake the exam at your home university if the latter is open at this time. If the second exam is a success, the course will be validated and the ECTS awarded.
