Yo!
I just wanted to say: if you're considering exchange, you might as well start thinking about it early in your degree! There's no
rush, as such, but doing so would allow you to better plan your units and the like. I was saving this one particular Linguistics unit to do during my degree because I thought it sounded most interesting; in the end, I couldn't do it, because it didn't correlate with my exchange study period (not well explained, but the point is: I stuffed up my planning because I left it too late). Not a huge issue at all, just a bit of an annoying one.
If you're interested
at all in exchange - even if you just want to see what's on offer - I really highly recommend speaking with Monash Abroad. You can go for an open advising session, and they'll be able to talk you through your options: where you can go, financial situations, different programs etc. Exchange really was one of the best experiences of my life, and Monash has a great student mobility program.
When I was there, the Monash Abroad office was in Campus Centre, on the second floor (down a pretty random corridor - it was never well signed). I heard recently that they were temporarily in the Menzies Building, though, so it might be worth asking around. But yeah, I really recommend speaking with them!
EDIT: Yep, according to their
website, Monash Abroad is temporarily (until the end of January) in Room S109 and S111 of the Menzies Building (the huge, dated building - very difficult to miss). After entering Menzies, that's just one floor up.
