# OCR MEI AS Mathematics Core 1 13/05/2013 Watch

1. How did everyone find the Paper?
I personally found is okay - easy, compared to the Jan one
60 for an A? or lower?
2. That was a really nice exam. I mucked up a little on 12)iii but got 4 and 0 out graphically, so should have picked up a couple of marks. Also had a stupid moment on the surds rearrangement question in section A, but other than that I'm reasonably confident of a high A
3. (Original post by Deceived)
They asked for the minimum y value. I assume you'll receive full credit because you put (2,-7).
Ok thank you very much! If thats true, i can only see that i've lost 2 marks! hopefully get above 90! Good luck all!
4. For the coefficient of x^3 I did all the working out and expanded the x^3 brackets and got -2560. But when I rewrote the answer to say that this is the coefficient, I forgot the - sign in front of 2560. How many marks will I lose for that because I got the right answers and you can see it it is just that I double underlined 2560 without the - sign?

For the circle intersecting the x and y axes I got 2+root 11 and 2-root11 but crossed this out and got different vales for y but still got the right values for x - how many marks have I lost there?

For the very last question I got k = 0 and 8 is that right? I f not do I get 2 marks (since it is out of 4) for it?

-2560x^3 so the coefficient of x^3 is 2560?
That might be okay. In the past papers I've done they generally condone having the x in the answer of a coefficient question. Depends if they ignore subsequent working or not.
6. If you've got C2 on Friday.Get off this thread - you're only dwelling on 1/3 of the 300 marks if you're doing the whole course this summer.

7. I thought 125 was 5^2 for some reason and so my final answer as 5^2.5 instead of 5^3.5. Will I only loose one mark? because I did all the workings out correctly
8. Anyone got a copy of the C1 paper?
9. Question 1. Can someone confirm what exactly it asked for? I skim-read it, presumed it said 'parallel' to the line, but people have told me it instead said 'perpendicular' to the line, which is obviously completely different.

It was -1/2
12. (Original post by Timmy12321)
It was -1/2
But what did the question ask for?
13. (Original post by simon105)
But what did the question ask for?
It asked for the equation of the line that was perpendicular to the line y=2x+something
14. ****. 3 marks down the drain. Such an idiot.

was it not parallel!?!
16. (Original post by student992)
was it not parallel!?!
no it was perpindicular

Apparently not. I read it as 'parallel' too. It's pretty gutting considering it's such a simple question
18. I'm adamant i did the right thing but someone put the paper up please?!
19. the average of paapers is meant to be around 58, but i think paper had a few questions that either confused some people or they didn't quite get the correct answer, so I think A will be around 55 maybe 54 if we are lucky

90% sure question 2 was perpendicular.
