Anyone think they know the raw mark for an A?
Well due to that cylinder question, I'm thinking the raw mark for an A will be around 59/60
2. (Original post by Heffalump .)
I did
-5x+3y-1=0
do you think I still got all the marks?:L
Absolutely you will. They say in the mark schemes to condone that kind of thing.

Phew! Thank you!

5x - 3y + 1 = 0
(Original post by Sail last)
It was 5y = -3x +7 since it went through (9, -4) or something
5y + 3x = 7
Thank you!

Ugh, I made the stupidest mistake then. I wrote the first gradient as 5/3 and used -3/5 for the question after that. Omfg. I must've lost so many marks on such a dumb mistake. I'm actually kicking myself right now :/

That question was out of 8, so I must've got 4 marks at most. I'm so annoyed. F this.
5. Even though this was generally a good test I hope that the ums graph isnt a straight line again!!!

It shouldn't matter - as you worked out the first gradient wrong, but the second right (going by your gradient) you should have only lost the marks for the first part, and then you should be able to pick up on follow through marks.
7. Are these the right answers
8. (Original post by aoxa)
It was 7.

You used the fact that the shortest distance will be to the midpoint, so 2/2 = 1. Your radius was root 50, so you used pythgoras; 50-1 =49. Root49 is the shortest distance, which is 7.
Oh man.
Are there any questions that you found difficult.
9. for the cylinder question where you have to find the positive value of r i just put r=4 should i also have acknowledged the r=-4 or will i still get full marks regardless?
10. this paper was easy, banter
11. also im wondering if anyone one knows each and every question that requires a statement of some sort because that is where i usually drop marks? thanks!
12. I always try and stop myself reading threads like these because I go from confident to 'HAH IM FUJJED' but for once I'm like yas, I got this

Like all of them? I thought that was the hardest C1 paper I've ever done. How did you find it as a whole?

I think the applied modules will hard this year too.
14. Anyone know of an unofficial mark scheme for the edexcel board of this paper yet?
15. thats exactly what I got
I got 108/5 or something similar not 31.
thats exactly what I got
17. (Original post by peterchristo2)

Did you find the paper hard?
18. completely botched the cylinder question and somehow SOMEHOW my brain didnt register that the I had the radius WHAT THE FUCUUUAFUAUFAFU., so i sat there like a moron knowing what to do for the circle question with the RADIUS and a diagram drawn out and I FOR SOME REASON DIDNT SEE THAT I HAD THE RADIUS=HYPOTENUSE. -______- shoot myself. How is that even possible....

There's the roots one, where you had to say (x+2) is a factor, and the maximum/minimum points question, and maybe the ones with b^2-4ac? Apart from those, I can't think of any.
20. (Original post by Lobster37)
anyone else?
I may have lost a few marks on question 6 where you had to work out the volume of the cylinder.
