Great. Your third year grade (which we need to be 61%) can be calculated as:
(Module1Percentage x Module1Credits) + (Module2Percentage x Module2Credits) + (Module3Percentage x Module3Credits) + (FinalProjectPercentage + FinalProjectCredits) / (Module1Credits + Module2Credits + Module3Credits + FinalProjectCredits)
If your Module 3 mark stays at 55% (i.e. the exam doesn't cause it to increase or decrease) and if the 65% for your final year project's post reflects the percentage for the final year project as a whole, we get the following:
(40 x 20) + (50 x 20) + (55 x 20) + (65 x 40) / (20+20+20+40) = 55 percent
So, let's assume the exam in Module 3 goes
so well that it pulls your Module 3 percentage up to 65%, and your final year project turns out to be better than the poster might have implied, and you get 75% for it:
(40 x 20) + (50 x 20) + (
65 x 20) + (
75 x 40) / (20+20+20+40) = 61 percent
So a 2:1 is still possible, but it's not going to be terribly easy. Does a 65% in Module 3 and a 75% in the Final Project seem achievable?
