Year 12s: what will be the first way you research your future options? >>

Computer science modules:

Was wandering if anyone can help me with the maths side of things in these modules as I didn't do A level maths. The maths part of computer science is making me really wary of applying for it but everything else looks great. I still got a strong GCSE grade B but will probably resit and get an A too, but I haven't been that good at science and only got B's at GCSE's and didn't like it. However, apparently computer science is completely different and they teach everything from scratch so any assurance would be great.

Ps- I have talked to many students from different quality Uni's like Newcastle, Nottingham, DMU and Lincoln who didn't take maths and sciences at A level but are all doing fine but I guess it just depends on the person.

Thanks again, any help will be very appreciated.
