1 module fail?

Hello,

I'm in the first term of university, and i'm studying computer science.

Anyway, I'm a little bit worried about failing a single module, I'm a pretty good judge of grades and results, I always seem to predict close to what i get in exams, and so far I think i will get 2 x 2:1's, a 1st (maybe high 2:1) and I feel the last module (Mathematics) is going to be a fail, its just been so long since I have done maths so I struggle compared to most other people, It's not something I'm horrible at, I just don't seem to cope as well in the exams...

Would the uni kick me out if i failed one module but did pretty well in the other 3?

Thanks
