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 :frown:

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 :facepalm:

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.

Edexcel, lol.

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

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?

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.
