Edexcel Maths Grade Boundaries.

What would you estimate the GCSE Edexcel Maths Grade Boundaries to be?

I took the higher NC on Monday, and the C yesterday. (6th and 10th June)
I noticed the answers, and I added up my marks to be roughly 160. (71+89).
Would this be enough for an A? Also, what would you expect to be the lowest value for an A?

Many Thanks,
