If there is a time conflict, as you mentioned in your question, between the Jumu'ah prayer and your classes, you have to give priority to the prayer. In addition, we do not think that University Administration will prevent you from such a thing.

Allah Says (what means): {And whoever fears Allah - He will make for him a way out.} [Quran 65: 2]
Allah knows best.
