In France, courses are evaluated on a scale of 20. 20 is the best result possible (very exceptional in France) while 0 is the worst result possible. 10 or more is generally required for a course to be validated.
An ECTS grading is associated to the classical French grading systems. The equivalence is the following:
Grade on a scale of 20
ECTS equivalent grade
Very good result
Second Chance exams
If a course is not validated (Grade F) after completion of the semester, a second exam can be taken by the student approximately 1 or 2 months after the end of the course. In case of need, you may do the retake exam in your home university if the latter is open at this moment. If the second exam is a success, the course will be validated and the ECTS earned.
