Binding study advice
The Binding Study Advice (BSA) applies to students who are enrolled in the first year of a Bachelor's programme for the first time. In short, this means that each first year student will receive a binding advice as to whether or not they are allowed to continue their programme at the end of their first year of study (formerly known as "propedeuse"). At the Faculty of Science, the required minimum for students is 39 ECTS. This means that you have to have obtained at least 39 EC of your first year courses in order to get a positive advice.

Should you have questions or doubts, or if you just want to know where you stand with regard to your study programme and your recommendation, you can always contact your student advisor. Naturally, you do not have to wait until you are invited.
