Okay, I'm gonna necro this threat massively.
Regarding various guilds/colleges are there any adventure paths/modules that feature the PCs trying to graduate/attend/etc.
I am doing a campaign where the players will be at a similar school and was wondering if there was any examples of that sort of game.

Maybe check out the Academy of Secrets module? I've not played it myself, but according to the description it takes place in Acadamae in Korvosa. It is a level 13 module though.

Crypt of the Everflame can easily be refluffed from a village coming of age ceremony to a graduation exam.
Crypt of the Everyflame is ''very'' beginner oriented though.
Godsmouth Heresay could also work with little modification: Instead of being random adventurers they're roped in as part of some Pharasman initiation (The lack of reason why the Pharasmaians would reach out to this group of low level adventurers was one of the weakest points of the module anyways. The problem is being kept secret so it's unlikely PCs would find it while looking for work and the city is big enough level 4 characters aren't that rare.)
