Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. (1/144)e^2 anybody?
2. (Original post by Abscissa)
(1/144)e^2 anybody?
I believe that's the accepted answer. I must have made an arithmetic error somewhere... So stupid.
3. 70 in C3 and 64 in C4 should get me an A* right? Annoyed that I made some silly errors today....
4. What exactly was question 2 and 3 anyone? Like the actual question.
5. anyone remember the implicit differentiation q?
6. (Original post by duncant)
would you get full marks for not multiplying by x^2 or -1 mark?
I Think -1
7. (Original post by TheNicholas)
I Think -1
Why would it lose marks? The answer's still correct just in an alternative form, right?

will 67 in core 3 and 61 in core 4 get me an A*?

I'd be surprised if you dropped a mark, it's still correct

10. Overall was quite a difficult paper, but I found what really made it worse was the time management, especially for question 9
11. on the markscheme, the integration by substitution q is only worth 6 marks, not 7.

Very likely.

Very likely.
13. These grade boundaries will be my only shot at uni
A* 5/72
A 1/72
B -3/72
14. wheres the community mark scheme at?
15. i really dont recognise that implicit differentiation answer...
16. Neither do I, if anyone knows question 2 and 3 please post it.

I think there will be a simply mark
18. When drawing the graph on question 9 did we need to include the entire graph or the graph between limits of t?
19. (Original post by _asha_)
Can anyone remember how to get the Cartesian equation in question 9?
I got 2x^3 - 6x^2 + 5x but i don't think its right
thats what i got, and values of minimum points were consistent between the two forms
