C2 June 2011 Edexcel - Paper and Solutions in the FIRST post.

Very, very surprised at these ridiculously high boundaries....69 is 90 ums so 70 is 91 ums?

92UMS, probably. I wouldn't worry about it, it should just mean that people did better than they thought. I think the circle in a triangle question in C2 just made people think it was a hard paper when in fact the rest of it was quite trivial.

no, these are rounded. 90 ums is not actually possible

68 = 89ums, 69 = 91ums

do you know what is needed for 77ums as thats what i need to get into uni? please.

Thanks so i probably got 92 im guessing ...more worried about s1...high boundaries for an s1 paper which was pretty difficult.

Seems like quite a few managed to get the radius question then, nobody at my school managed it.

the radius one was by far the poorest answered on the paper nationally! but it was only a 3 marker.

Actual

100UMS - 75
90UMS - 69
80UMS - 62
70UMS - 54
60UMS - 46
50UMS - 38
40UMS - 30

I predicted 4 too low for an A, way off

A lot of people just guessed the right answer (2) but I can't really see them being awarded marks for that... Anyway, I don't think that's the reason for the high boundary, I just genuinely think the rest of the paper was fairly easy!

no marks for part b for guessing, however, full marks on c, if correctly solved using the lucky guess on b

Are you sure? The mark scheme would suggest otherwise.

Special case: If a candidate states an answer of r = 2 as a guess or from an incorrect method then award M0M0B1. Such a candidate could then go onto score M1A1 on part c.

I hate you, C2.

I disagree with that. The volume question tricked a few people (not defining one of the sides) and the integration was slightly trickier. There were plenty of questions out there to catch people out, such as the missed solution for one of the trigonometry questions.

You have the MS for C2 paper?

The integration question was pretty standard and the volume one was the same. Those were both styles of question that had come up in past papers and were quite easy I thought. How else would you explain the high grade boundary if people didn't do better than in previous papers?

Mark scheme.

Explain to me why June 2009 paper had a 100 boundary of 69, yet it was easier than the June 2011 paper?

Thanks!

And that is clearly a matter of opinion... For there to be a lower boundary in '09 people on average must have done worse than in the '11 paper, suggesting that 11 was easier.

How can a paper with the trapezium rule contributing 6 marks be more difficult?

Actual

100UMS - 75
