Hi, thanks for your replies.
@Jessica Booker - to reply - in 2nd year i had 4 modules (less weighting than third year) but got (high) 2.2s in all 4 - one was optional so only 'added' to my final grade as extra points, but is on my transcript so unsure whether to include this. in third year I had 7 and got 2.2s in 3, 2.1s in 3 and the pass (31) in one. then fourth year i got the first - although it was for a project - which counted a quarter of my degree.
so my track record for written exams is not the best. am just unsure how much firms (in particular US/MC) will consider my better grade in fourth year as proof of academic improvement?
