Is there a minimum number of credits you have to obtain in the first year of the BSc Tourism?

Yes, A Binding Study Advise (BSA) applies.

If you study nominally, i.e. exactly according to the program of your study program, then each academic year consists of 60 credits. The standard that has been set for the BSA is 42 credits for first-year courses. In order to enrol in your study program the following academic year, it is therefore necessary to obtain at least these 42 credits in first-year courses.

82% of all BSc Tourism students continue to the second year. That is a lot compared to other programmes.
