I'm in the same boat lol... I'm alright at maths but I really don't want to do it at college level. But I need to do get into a good uni for Computer Science. If you wanna do Computing get a hard start on programming, if you haven't already. Try Python to start with and then move onto a language like C#, like I have. As for maths, well, maths isn't actually that hard when you put your mind to it and use your time wisely; maths becomes almost easy - at any level.
Anyway bai bai Mr.Stark...
