Do I have to sign up as soon as possible in order to get a place in my preferred courses?

No. The places are not allocated according to the principle "first come, first served". Please just make sure that you don't miss the deadlines.

Places in courses with a limited number of participants are allocated according to a random procedure after that particular registration deadline. The results will be available on the following day.

In courses without a limited number of participants, each student will get a place, provided that he/she signs up in time.
