Messed up AQA Grade Boundaries?

Hey guys, hope everyone did well, blah blah.
I got into my firm but am a bit confused re: grade boundaries.

I have been on AQA to see and they say

Sociology 3 45/60 is an A, but I did this paper and my results are out of 80 and I got 56, but was given a B. According to this boundary I should have an A*? I don't see what's going wrong?
Same for Sociology 4, 61/90 is an A* and I got 88/120.
Am I supposed to be doing some form of conversion for this to find out how I did?!

Why is the boundary so ridiculous?
