YES!!! Been trying to remember what that questions was, and what I put on it. Good to finally see someone with a similar answer.
Aha me too. did u guys use quadratic formula to get it?

That is not true

For an A* overall, you need 480 UMS and 180 or more from C3 and C4. There's nothing about core modules, you could get 80 in C3, 100 in C4, 100 in S1, 100 in S2 and then 50 in C1 and C2 and you would still get an A*.

And it certainly doesn't have to be 90 or more in both C3 and C4 - you can get 80/100, 85/95, 89/91 etc. (My combination was 100/84).
The fact you got 100 and 84 gives me hope haha, I had a weak exam. Will need high 90s in C4 (the module I like less as well)
unofficial mark scheme?
Everyone's agreed on this so far - I have workings for some questions throughout the thread

4. How many marks was the dy/dx smaller than 0 question?

Exactly it's not ideal but at least you know that it is still possible

and what are we expecting c4 to be like?

2 marks I think ..

Very true, a chance is all I need I had better get to work then!

I am hanging on by the skin of my teeth to my offer right now haha
9. Does anyone know if there's a list of how many marks each question and part was worth?

Good luck I know just how stressful it is
11. Rough grade boundary guides. Was defiantly a harder paper 65for A* or less??? Thoughts pls

2 marks I think ..
How confident would you say you are? I cant remember if was 2 marks or 3marks
13. what was question 5

Fairly confident ... I believe the first part was 5 marks and the second part was 2 marks

Can't remember the values I got from solving the trig equation but I got cot^2(x) - 3cot(x) - 1 = 0 so tanx = 2/(3+/-root13) does this ring a bell for anyone?
Yhh i got that, I think I got 4 values after, one of them was 0.294 cant remember the other ones, was this q8 btw?

64-65 for A*
59 for an A .. I don't think they'd go any lower .. IMO
18. What do you lads think you got?
19. Question 9 was ******** how was you meant to solve it?
20. (Original post by Fas)
Realistically looking at about 87-93 ums, depending on where A* lies. I haven't seen the paper yet, so will give a more accurate prediction tomorrow, but judging from the reaction, A* will be around 65/66, potentially 67. Can't see it going higher or lower than that tbh.
Cheers bud, looks like an A* is still more than possible for me as long as i do slightly better on C4!
