Yeah. Well there's an AC + Group Activity in 3.

I like it how you made an account and posted after UBS has closed its date :)
I think approx. 1000-2000 people for UBS. UNSW Banking and Fin., not too sure. I think UBS accepts around that number, but can change ofc. B&F depends on the sponsors, so around the same.
They only have this: https://www2.deloitte.com/au/en/pages/careers/articles/deloitte-private-young-achievers-careers.html

Bach of Comp Sci & Maths is a bit overrated. But that's a course that OP can do that allows him to major in both maths and computer science.
And OP, you don't need SDD/IT. Just 3U like what sqrt said.
