Every semester we ask all lecturers to share their old exams with us. If an exam or an entire course is missing, you can usually find it in the GRIPS courses of past semesters, which are mostly freely accessible. The student council does not have solutions and therefore cannot provide them.
Tip: search by course name, keywords (e.g. GRIPS), years (e.g. 2019), or semesters (e.g. SS 22, WS 21/22).
