Considerations regarding the registration of optional subjects:
- The enrollment is always individual by subject.
- The regulations do not allow enrolling electives of a course, if at least it has not passed or enrolled a subject in that course
- As a corollary, you can not eliminate a compulsory subject from a course, if it is the last of that course and there are electives enrolled in the same course.
- In the electives, the subgroup change is always enabled. It will only be prevented by the fact that there are no other subgroups with available places.
