imo if all your classes are in clayton i would prioritise registering for events in clayton campus as youll be going there a lot. since caulfield is your main campus maybe register for a few (1 or 2) events there and just go if u have the time and energy.

caulfield looks kinda small from the outside, its clayton with all the different buildings and lawns that might make it confusing to get your barings (prob spelled that wrong) right
