In order to register for the course BE2M99ZVT, the student must have registered for the required number of courses in the group BEZBM no later than in the same semester.

During a review of study plans, the course B2M99ZVT can be substituted for the course BE2M99ZVT.

It is not possible to register for the course BE2M99ZVT if the student is concurrently registered for or has already completed the course B2M99ZVT (mutually exclusive courses).

The requirement for course BE2M99ZVT can be fulfilled by substitution with the course B2M99ZVT.

It is not possible to register for the course BE2M99ZVT if the student is concurrently registered for or has previously completed the course B2M99ZVT (mutually exclusive courses).
