do invigilators give you extra time in UK???
no, they didn't. It was a 90 minute exam, even with 9 questions instead of 7 the total of the paper was still 75 like all the past papers.
2. Q7 Part C They Wanted The Answer To 3 Significant Figures But I Wrote It To 2 Significant Figures So Will I Lose Marks For That

Wtf! Barely dropped 10 marks in every past paper and now I am sure I at least dropped 15-20 ******* marks! That is so annoying! Looks like it will have to be a retake I am so prone to making stupid errors, on the second part of question 4 I was trying to use the first part of the question
Yeah i know me too!! that question is just worded wrong if its a second part you would naturally assume they are linked, so unfair can't they use different letters to make it clear?!
I just ended up infinitely substituting lmao, nearly blew my brain

I would guess - 2 marks for Q8. Not sure about 7, you've clearly lost the accuracy mark for b but I am not sure if you will lose one for a.

If that is all you have got wrong you are looking at 71/72 which I think will be 100UMS
No, I got others wrong as well: alpha was incorrect for Q3a, which I followed through with. 8ii) thought that cot2x had no solutions and messed up one other one for the other half. Q9ia) and Q9iib) probably lost me another 6 marks. So I'm looking at about 60-64. Hopefully an A? I will +rep you for solutions tomorrow as my rep is suspended until then, sorry.
5. ok guys this wont exactly be 47 or 48 for an A like in M1. nothing is on M1s level hardness. id say the grade boundaries will optimistically be 55/56 but realistically about 57 for an A and you add either 8 or 7 on for each grade so maybe 62-65 for an A*
6. Edexcel, lol.

I entered the exam hall confident and pumped to get my A*.
I left the exam hall completely raped from all angles by that paper.
ROFL

No, you have to reflect everything in the positive x axis in the y axis.

I did the same in q4 also lost 15 marks minimum.

no because ¦x¦ allows ln to have negative values of x and thus reflection in y. I didn't put about the assymtopes but surely that wouldn't a mark right?
17. I'm gutted. I was fine on all the past papers, got nearly 100% on c1 and c2, then ****ed up this one. I think I may have got 50/75 for it, probably lower. D: everyone here seems to be really confident, and I REALLY don't want to retake, but I guess I'll have to.

it varies, lookin at c3 january 2009 there was only 8 questions, so some people thought it was only 8 questions in this paper and left their paper without doing question 9 ouch!
