1. (Original post by кяя)
I don't give a **** about UMS since where I'm going don't look at it but they do look at As. Now that o look at the unofficial mark scheme I think I did okay anyway so hopefully ill get an A overall.
2. Every time after exam i have some kinds of worries about i did not get all method marks since i jumped too quick. In the circle question i used total differential to the circle equation and i'm not sure if i got all M marks.
3. I think if u factorise (3x^2 -48) you get
(3x -12)(x+4)

So, the geometric series one where you had to find a and r.

I wrote down both equations, then did about a page's worth of rearranging and trying to make it work. Ended up with some disgusting cubic. Any idea if I'll get any method marks?
Yeah exact same problem here!

Btw I may be able to get the paper if you want it?
Sorry to weigh in but I agree with those who do not think the UMS will move massively. This was not a superhard paper and utilised techniques that we have seen before
7. I think I got 46-50/75 on C2 and 65-70/75 on C1, Do you think an A overall is still achievable with those scores if I do very well in Statistics?(and I do find statistics to be the easiest of the 3 papers for me personally)

but when you apply to uni they look at your as results
They look at your predicted grades and you can easily persuade your teacher to give you a higher predicted grade if you tell them you are retaking and are willing to work a lot harder

Aim for at least 70 in S1 I would say, good luck

You'll probably lose one mark for each
Even for the first one?

Last year they organised a petition and everything. 100 UMS went down by one mark
12. Personally I think 63 marks for an A, and 75 for 100 UMS.

61 for an A. 74 for 100UMS

I did this. It's imo the best way to do it and applies relevant knowledge from c1 and c2. I would be surprised if this wasn't in the mark scheme

Edit: just checked Arseys Mark scheme. This is exactly what he did.
Thanks so much!

No way 74/75 for 100. This year much easier then last years paper.

17. How did I fail the integration question it was so easy looking at it ffs exam pressure

18. Do you think I'd lose marks if for the first question i did up to x^3 instead of just the first 3 terms?

Pretty much all A2 Students say this for every Maths paper. Last years' was very easy. Hardest thing was circle theorems which are still simple and easy trapezium rule marks are included.
