Are there good quality mods that add more students(named ones with at least a backstory) and areas for the college? It is a college after all, but only 3 students? Wow...
Plus, the college is really pathetic looking and even the bards college is a better college than this.

Also, are there mods that add quests to the mages college?

only one i recall is over on nexus ... Dalls_Arch_Mages_Tower ... he was working on this not sure if ever finished.
there is one that changes the looks (couple of those out there) and one that expands the ruins and encounters in the town itself ....
