Just helping out :T
UNSW is just as good if not better at commerce,but the difference is negligible,so either University is good. Well instead of the hogwarts buildings you get a nice lump of stairs everywhere for you to excercise hahaha.UNSW campus is pretty good looking too.(bit more modern i guess)
Yeah I would think it'll be really hard tbh. Actuary itself is quite competitive, but you'll definitely have a good chance to land a job with the skills learned in the commerce sector(accounting won't be too hard to land a job in)
Yes you should definitely go,it's a really good chance to meet employers and ask any potential questions you may have, plus they give out good information about the program itself and usually an experience or two from a current cadet (although you can also ask that during the meet and greet session). I may also be there, maybe, haha.
Seremify might also be there.(not sure though, busy life for him
)
