Oh, in which case the integral can be rewritten as:
integral of 12 - 3cos8x correct?

6-3cos8x

What was question 4? and I didn't see the y on the right in the last question but apart from that did the integration right but obviously got the wrong equation so many marks lost?????????????

I've not seen this paper but June 2014 has at least 7 marks which were scored by very few candidates -- checking that the lines were distinct in 5(ii), the last two marks for the graph in 7(iii) and the last four marks in 10(i). From looking at the reactions to this paper it seems that there were no particularly challenging questions, so I would expect higher than that for 90 UMS.

I'd estimate it to be 60-64 for an A*

For the 3/8 pi answer I got 3/8 pi - 3/8 instead of plus 3/8. How many marks would I lose?

Oh yes, the negative six multiplies by positive 1. Hence 9 - 6 = 3. Urgh this is very annoying. Would I get marks for going through the following method correctly, just lose accuracy mark due to silly mistake?

what grade do people think 61 marks will be?

A or a low A* I think.

Anyone got a copy of the paper? I want to predict any ecfs i got and my total mark. Cheers.

Absolutely no clue, it's possible but I'm not too certain

it will be 60 for A*, guaranteed.

Probably none. FT (follow through) marks as they are called in maths are given very sparingly. Usually one mistake will cost you the rest of the accuracy marks for that question, although method marks are still available.

think i got around 58-56 on this paper and 60 on C3, are my chances of an A* gone would you say?

Ye sorry, method marks! :smile:

Didn't end up with the correct answer for Q4. Q10ii I set up what I believe to be the correct differential equation and integrated it including +c. Messed up the next step! How many marks would you estimate id get for that? Other than that I found the paper okay, 61/62 A* id say!

it was posted a while back. this is not my working, there is one more step where you have to simplify the 1/x^2 by multiplying top and bottom by x^2 http://www.thestudentroom.co.uk/attachment.php?attachmentid=556031&d=1466772342

If i put, 1/44+e^2 how many marks would i lose?
