I think it's about 25%. Don't take any chances mind. Get as much as you possibly can. Unless the second one is considerably more difficult, you should do fine. 62% is a fairly good mark for the other one.
Hi Loosehead, thanks for your answer - I was looking for a percentage figure in the second exam, that I'd need to achieve?
40% is the basic pass mark for that module, I'm in the first year of a BSc in Psychology with Criminology. I'm pretty sure that's the standard mark to pass the first year with most universities in the UK.
