I dont know, ive solved all previous papers at least twice, and i think this is easily one of the most difficult papers, i predict an A boundary similar to that of May June 2010 variant 2
Hehe......come on 2007 papers was much more difficult. Moreover you did this one under exam conditions, so its pressure and stress is highly significant.
Personally I found it rather easy, especially the calculations. The theory part however was a bit tricky.
Well, let's only hope that we both afford an A in the paper.
