For non-standard subsidiary subjects, an individual application must be submitted to the board of examiners for computer science for the attention of Computer Science Academic Advising. The student council has examples of approved applications available as a guide. However, copies of these applications will not be accepted. As part of the approval procedure, the examination board for Computer Science agrees a study plan with a minor subject representative from the other subject, who is appointed on a case-by-case basis. It is quite possible that such a plan is not achieved and the minor subject cannot be chosen - there is therefore no entitlement to a non-standard minor subject.

There is a special regulation for the subjects Physics, Chemistry and Mechanical Engineering. An application must also be made here, but no special substantiation is required. In addition, there are appointed contact persons for each of these subjects.

The following non-standard minor subject plans have been agreed to so far.
