Is there are a grading structure to the course? In that I mean A, B, C or D or fail, pass, pass with distinction etc. Also if it is just a pass thats required to what standard or percentage does that have to be?
I think it's a simple 'pass' or 'fail', with 75% needed across the whole course for the pass. Just in case I'm wrong though, check out the 'Study Skills' section at the top of your course - that should have all the information you need in it.
