Uni course credits and grade calculations

Hi, I'm asking for my daughter in her final UNI year of Spanish BA (4 year course). Math is not her strong subject, nor mine.
This is the question she is asking me to calculate, which I can't so would be so very grateful for anyones help?
These are her marks so far:=
YEAR 2
30 credits - 64
15 credits - 63
15 credits - 28
15 credits - 72
15 credits - 66
30 credits - 46
120 credits for the year.
YEAR 3 (year abroad)
30 credits - 40
YEAR 4 (FINAL)
2 x 60 credits and 4 x 30 credits, 240 credits in all.
Her question is what does she need to achieve this year in each module to get at least a 2:1?
So very grateful for any help offered?
Thank you

This looks unusual for the Open University. Are you sure this is the university she's at?
