As a student at KI, you have both rights and obligations. For example, you have the right to a good work and study environment. But you are also obliged to take note of and follow KI's rules. They govern, among other things, examinations, credits, authorizations, study breaks and registration. You can read more about this on KI's website, Student Rights.
We especially want you to understand what is meant by cheating. In academic contexts, it is never allowed to present someone else's text as one's own. For group work, special rules apply. It may be permitted to collaborate on a submission task, but not permitted to write it together. There are also many rules that apply to written exams. Read them carefully and come prepared.
