That’s an . . eclectic list.
Some of them, you and everyone else are a low possibility for. Some of them are possible/likely.
How did you come up with that list of schools?
Also, some US unis will give you credit for A-Levels (and some even for AS), which may save you time/money.
Some UK unis also have some flexible programs that allow you to study different subjects (or switch, in Scotland).
Canada also exists and unis there tend to feature a fair amount of flexibility (compared to the UK).
So what do you want out of undergrad and how much are you willing/want to spend?
Some unis have International scholarships (Minnesota comes to mind).
