my predictions from earlier are ever so slightly higher ...
Looking at the June 2013 paper, I don't think this was much easier. I'd put my money on my boundaries lol.

So if i Copied out the question wrong would I not get error carried forward? I wrote 1000 instead of 100 for question 4 so I got ln0.005/ 40 instead of ln2/40. I then used my answer to get another answer to the two marker for part b. How many marks do you think I will get? (Part a was out of 4)

Don't think you lose a mark for the +-. In fact, I think it is necessary because cosx can be negative and without the +- you assume it to be positive for all x.
Arsey didn't use a +- , I assume he's right. But then again your right since all we were told was p can't equal 1 or - 1 so theta can take values that make cos negative and the sqrt without the +- can never be negative I think?

Guys could some nice person tell me how many marks I lost and guess ums, I think I made the following mistakes: 1)b) I left my answer with sqrt the whole thing and a +- infront of it. 2) a ) my asymptote was -3 not -5 . I then reflected this for part ii so my ii asymptote way y=3 will I get ecf?And finally for 8)a) I only expanded the left hand side to 1+2sinacosa on to and 1-2sin^2 a on the bottom .I need a maths a* for uni so I'm worried since 8a) was 5 marks .Thanks

I can't see them taking a mark for putting it. It's not wrong. I think the people who didn't put it are at the risk of losing a mark.

Q4 I think. It was the one where you where given the temperature and had to work out lambda. I wrote 1000 instead of 100 so i got ln0.005/40 instead of ln2/40

real shame and so obvious ...
I hope the marking scheme works in your favour as much as possible
