[a bit of a back story: am in Y12, going to start applying to universities (undergraduate) in 4 or 5 months. Architecture and Computer Science (/stem subjects) are my two career choices. I've been going through a lot of talks with parents, as I was leaning more towards computer science but they were completely against it, so now I'm trying to find a way to continue studying it. Unfortunately, the more research I do, the more unanswered questions pop up in my head, here are a few..]

1. If I study architecture as a major, am I allowed to take classes, if not minor, in a science/maths subject.. maybe computer science?

2. For that I've been researching, getting answers from websites saying if you enroll in an architecture course, you won't have time for anything else - you'll practically be living, eating and sleeping in your studio. Is that really the case?

3. Disregarding minors, the USA (UCB, Georgia Tech, Cornell) or the UK (UCL, Cambridge)?

If anyone can help, opinions and feedback are high appreciated. Thank you so much :)
