# I want to figure out what grades I need this semester to scrape a 2:1? watch

1. 3rd year counts for 1/3 of my degree: I got 42, 44, 52 and 58% (all 20 credits each) 4th year counts for 2/3 of my degree: So far I got 47.2% (worth 50% of a 20-credit course), 52% and 58%. I still have 2 exams to do this semester (one of them counts for the other 50% of my 20 credit course and the other counts for 10 credits) then I have a 10 credit project proposal and 40 credit dissertation. What grades do I need to scrape a 2:1 (so literally just get that 60%?) Thanks in advance!

Your second year result was 49%...

This means that you need .... in third year

Your third year grade is determined by (49/3) + (2*x/3) where x is your third year result...

and you need this to be greater than or equal to 60...

Rearrange for x to give x = (3/2) * (60 - (49/3)) = 65.5% so 65.5 or greater in your third year is required...

Unfortunately I cannot go any further as it is not clear where your 52% and 58% from this year have come from.

But you would break your third year down and perform weighted (where the weights are the percentage of credits) average calcaluations to find out whether your overall grade is 65.5 or greater...

Eg if you only ever had 3 units in this year, and got 40%, 60% and 70% in them and they were worth 25%, 25% and 50% of the total credits respectively then your overall grade for third year would be (40*0.25) + (60* 0.25) + (70*0.5) = 60%.

Hopefully this teaches you how to work it out good luck
