# OCR (not MEI) C1 - Wednesday 13th May 2015 watch

1. What did you get for the simultaneous equations??
2. (Original post by Katie.R.S.)
What did people get for the equation of the line through the mid point of AB?
6x+4y-29?? Something like that... Might be the wrong question..? Sorry...
3. (Original post by AlarmingMonkey)
K<-25/8

Below the vertex
Dammit, I put that but convinced myself out of it
4. Is it possible to get an A overall if I get a B in c1 a high A in c2 and an A in stats?
5. I also got stretch sf 1/3 parallel to the x axis
6. What did everyone get for the last indices question? I feel like I messed it up!
7. Also, answers for the differentiate X^(1/3) where X=8 or something?

yeah you just need 240 ums overall. you could get a C and two A's and still get an A

Has to be tin the form "5^k"
11. Few questions. 1) is parallel to the x axis same as in the x direction
2) how many marks will is loose for writing (5root5)^3=5^11/2
3) for the area I worked out a y coordinate wrong therefore my area was wrong. How many marks will I lose.
12. I got 5^4.5 for the last indices question

13. What expansion did people get for simultaneous equations. The rest was a breeze however I spent a good 30 min + solving :

3x^2 + 20x - 22 = 0

As y=-2x-5 so I just substituted. I think I got it completely wrong but I tried 5 different ways and came to the same expansion which I couldn't simplify...

Really hope grade boundaries are not higher than last year :/
14. It had to be in the form 5 to the power something, I got 5^(9/2)
15. what did people get for a on question 9i (i think)???
16. (Original post by iloverobkardash)

Would it not be 5^4 x 5^1/2??

i got 1/12... probably got that wrong

Has MR M / K stopped doing them?

I don't use TSR much, does he do them for OCR A level? I just remember him doing them at GCSE for edexcel.
19. and what did everyone get for 10iii???????? area of PQR

I got that for whatever question or was

I got something like -3/16, I think I did it wrong
