This question was asked a couple of months ago and answered in these threads, by me for Cambridge and with u/Naugrith, u/CptBuck and u/Feetofclay chipping in for Oxford and other European universities:

How were students evaluated in Medieval universities? Did they give oral or written exams? How long did they last?

I'm a student at Cambridge in 1300. I've been accused of cheating on an exam. What are the standards of evidence needed to discipline me, and what is my punishment?
