If I fail this module, how it will it affect my grade?

I am doing maths and further maths, I decided to pick up M3 (13th module) which I am sitting this Wednesday. I am definitely going to fail it, I tried revising it and I literately know nothing, I can't even do the first exercises in the first chapter, let alone any past paper questions. If I get a U in this module will it have any affect on my grade?

If it's your 13th then it won't affect it whatsoever.

So it won't affect my chances of getting an A star or anything?

Just don't turn up to the exam if you haven't done the module. It doesn't count towards your grade.
