How can I deregister from my registered exams?
In the logged-in area of campo in the menu tab
My Studies → Show my enrollments you can view your registered exams and deregister from them in the column
Actions, if your Degree Programme allows this (see e.g. Regulations on deregistration deadlines and make-up exams). In the following pop-up, you simply have to acknowledge the notes and click
Next. At this point, check again whether the test was actually canceled so that you do not get any problems later.
Caution: This page also lists other types of assignments, such as courses you are taking. However, these should also be marked as such in the title, rather than as an exam. Also, the exam number in the title can give you a hint that you are looking for the deregistration option for the correct exam.
