Im looking to study computer science in uni. I was wondering what uni's are best for it, and what the requirements are. I heard aston is quite good, and thats point based i know, but i cant seem to find anymore info
Look candidly at your likely grades.
Apply to those universities with requirements corresponding to those grades (and subjects), and are as highly ranked as possible.
In terms of subjects, different universities have different interpretations of what's necessary. For example, some may ask for maths, others don't. Really depends on the institution.
Look around on the internet at some online prospectuses.
