Bsc Mathematics & Finance vs Bcom Finance

Hey, I'm a first year student currently taking Econ and CS and I plan on going into either finance or mathematical finance. I already tried emailing the guy lsited on the uofa website to ask about Mathematics and Finance but I haven't gotten a reply back 😭. Anyway here are my questions:

1. Does Mathematics and Finance have the same access to Alberta School of Business events?

2. What GPA would typically secure admission into Finance along with Mathematics and Finance?

3. Is it possible to pursure a CS minor or double major with Mathematics and Finance?

Thanks!!
