# WTF was that C1 exam... watch

1. (Original post by anonymous2410)
what did you get for question 6 part b? where you were given the x coordinate (-1) an you had to find the equation?
I got 3root 10 so k=3
2. whats peoples predictions for this papers grade boundaries??
3. (Original post by RebeccaButterfly)
I got 3root 10 so k=3
no that was question 8 and i got k=3 as well. i am talking about question 6
4. For the integration question, I believe it was question 10. What did everyone get for C?
5. (Original post by RebeccaButterfly)
Yeah I got that
could i of used completing the square, i got 5 root 3 or 2

i did use the quadratic to check my answer after which was correct but i thought since it was negative and the question was >0 that there was only one root ?
meaning the negative is just nothing?
or am i wrong?
6. Did anyone do 10B??????

For the integration question, I believe it was question 10. What did everyone get for C?
c=2

Did anyone else find that k=11 in two different questions?

Yes!
10. what the hell i got something like c=-16

I got this the first time, but went back at changed it. I think what you must have done is written -8 instead of +8 by accident, which gave 16, rather than 2. Don't worry, I expect it'll only be 1 mark :-)

yeah some people got c=18 or -18,
i think the correct answer was 2, you must of integrated wrong
13. (Original post by Jordan97)
For the inequalities question did you get p<3-2root2 and p>3+2root2
I got 3+4<7
and 3-4>-1
Or the other way round

1 mark could change my life.

I think this is wrong, did you do 12/2( 17k x 2 (11)1500) + 9(32k)??
erm lots of people are saying different things for this so im not sure im right, but i did 12x32000 as they earnt the max for 12 years + 4(34000 +7x1500) gave me a number around 500000
16. I got £625000 too

That could be a bit dramatic Just make sure you check over all your answers carefully in C2, and by doing that you will probably pick up a mark, evening it all out.

I did 9x32000 because if you think logically:
17000
18500
20000
21500
23000
24500
26000
28500
29000
30500
32000 Which is 11 years
19. She reached her maximum salary of £32,000 in year 11. She works for 20 years.

I did:

[Sum to 11 of the arithmetic series] + 9 x £32,000 which gave around £575,000
20. fml
that was HARD FAM
