Time slots

Schedules & time slots
An academic year consists of 2 semesters divided into 4 blocks:
- Semester 1 consists of block 1 and 2
- Semester 2 consists of blocks 3 and 4
When attending more than 1 course in a block, make sure to choose courses that fall into different time slots, to prevent your lectures, workgroups or exams from being at the same time. It is not possible to take more than one course in a block in the same time slot. Please refer to OSIRIS to see which time slot a course is assigned to.
Please note: the time slots shown for courses in period 3 and 4 (2023-2024) are not yet final, and may still be modified until 20 September 2023.
