Enrolment of students into groups
Students may enrol in seminar groups only at designated times. This starts at the beginning of the course enrolment period and ends with the end of the course enrolment change period.
A student who has registered or enrolled in the course without problems may register for (at most one) group. In case of problematic registration, the seminar groups of the respective course cannot be selected. The instructor and the study department may include a student with a red registration in a group. Groups have a capacity limit, you can only register for a group where there is space (you cannot register over the limit and e.g. wait for another student to withdraw).
There is a control application showing the history of students logging in and out of seminar groups. A similar option is also available to the student (it prevents discussions about who logged in/out when, why they are not in the list of students, etc.).
Logging into multiple groups:
In some cases it may be advantageous to allow students to enrol in more than one group of one course. If you choose to do so, you will need to set the “multiple logins allowed” flag in the definition of the relevant group. This is an exceptional solution.
You can also enrol students in bulk using the app
