Attendance 2/3 of class attendance.
Disciplinary approval:
Frequency: Last year''s frequencies are valid this year.
(2/3 attendance at classes). 1)
Final grade (=average of the grades of the 3 modules/3) ³ 10 2)
Minimum grades: given order 04/2020 - there will be no minimum grade for the tests.
3) The grade for a module (obtained by test or exam) is valid throughout the year 2024-2025 (Recourse or Special Exam).
A priori, it will not be valid for subsequent years.
4) In appeal or special exams,
a failed student may repeat the assessment part of the modules in which they had a grade lower than 10 points. _______________________ Improvement: Students approved in the “normal season” can “improve” the modules they want by registering at CLIP with “Improvement”
