I can't register for a course. It says "max 4".
This means that you are registered for the maximum of 4
courses per block. You can solve this problem by deregistering for
courses that you do not or no longer take. If
you wish to take more than 4 courses, please ask permission from
your programme coordinator. Next you visit the Student Support Desk
with the proof of permission (for example an email). The Student
Support Desk will enroll you for the course units in question. If
you are registered for two bachelor or master programmes at the
Faculty Economics and Business, you do not need to ask for
permission from the programme coordinator. You can visit the
Student Student Desk straight away.
