Mr Kibris, the guy who did the unofficial mark scheme for paper one (with all the questions, answers and number of marks) has said he's not doing one for the second paper :frown:

predictedd boundaries
A* : 165 - 168
A : 135 - 142
B : 95 - 105
C : 60 - 65

That's a good shout. Unrealistic to assume grade D people have to get 120 out 200 for a C lol..

No way they will be that high that's ridiculous they go up 3 or 4 not 15 marks...

It most definitely wouldn't be that high, I would say maximum for an A is 140/200

Hi all,
For the last question, I made one mistake early on, when doing the 1/2abSinC, but then did the remainder of the steps correctly,but my answer was far out due to this mistake. How many method marks do you reckon i'll get?

Wasn't 1b) 10%? There were only 2 numbers below 18, 16& 14, so that's 2/20 which is 10%

the non calc and calc were fairly easy compared to previous maths edexel examS so the grade boundaries will be v high ,roughly:
A*-170/200
A-150-169
B-115-149
C-95-114

your predictions are miles off an A* is roughly 160 an A grade wont be any higher than 135 the exams this years were not that easy
