Well in the UK the subjects you select is very closely tied to which University you can go to. Some universities require maths and will not accept people who haven't done it (sometimes even more advanced maths is required).

Some universities don't require maths and so will teach it to everyone who's applied. Some don't require it but force you to take a year of it if you haven't done it. and others require it and reject you if you haven't done it.
