I wouldn't have even thought to use! Damn hopefully I'll get a few method marks.

these are my estimates

100% around 70-71
90% around 63-64
80% around 56-57
70% around 50-51


sadly thats dreaming big time
id estimate 73 for 100
65 for 90
59 for 80
54 for 70
and i honestly cant estimate lower than that, boundaries will definitely have a wide spread though

Do people think this paper was harder than June 2014?

I'm feeling like 64 or 65 for A*?


Posted from TSR Mobile


I don't think it was a massively difficult paper, it was just strange types of questions. They could all be solved it just required more time to be spent on them, plus there were 9 questions which is more than usual (with exception to 2014). Considering how many people didn't like it i think A grade would be 59/75 although i think a fair grade A could go up to 61/75.

Those grade boundaries would be harsh, considering the exam is out of 75?


UMS (sorry I did not write it)

Any chance of an a* with 66?


Judging by the thread, I think you would. I hope so as I also got 66. This was harder than last year's for me and I've pretty much aced the mocks and past papers.
how many of you left that sec2A tan2A question?
The paper is out of 85...

well I hope so because that's what i wrote down as well
Original post by TheFuhrer
I just question whether you were well enough prepared?


gr8 b8 i r8 4/8 for making me reply...
depends if you consider 70+ on every c3 paper available with runs of 3/4 papers 75/75 at a time unprepared...
i got unlucky with one question and got too wrapped up on it to check my answers, thats on me, but i assure you it was not a lack of preparation
Original post by TeeEm


Dont you think 1b is wrong? Arsey shud have a plue or minus there.
