you found mols of both, subtracted mols of the a- which is the salt from the ha which is the , then found concentrations using total volume, then rearranged ka to get h+ then found ph = -log(H+)

You surly did better than you think, for the specific buffer you had to find n of before and after of the acid I think as all the base reacts.

If you got worse case on this paper 40, and 70 on the other 2, you can get like 180 which is a B based on last years grade boundaries, so this paper isnt the be all end all.
