# OCR MEI - C1 - 13th May 2015 watch

1. (Original post by Liam_27)
For the transformation question number 10, did everyone get that to get f(x) to g(x) it was f(x) - 36? Also once proving g(-1) was a root did anyone get that the 2 other roots were -1 again (repeated) and then 6?
Yes I got -36 and x=-1 which is a repeated root

3. I damn I didn't state it was a repeated root or put it under one bracket with ^2. Think I lost a mark?

4. I put k<-14/3 for the final question....worked everything out but mucked up the inequality do you guys think I'll only drop a mark or more or will I be okay?..

9. It was easy up until the point question 12 part (i) and partly the proof question. How'd everyone else find it?

my teacher told me that if you lose marks on questions like that one you cant get an A. Say goodbye to first rate education, Tomas. Say Hello the university of lincoln.
11. What did you guys/girls get for question 1?

What did you guys/girls get for question 1?
r=sqrt(A/pi(x+y)) I think
13. How do you guys write math stuff and it appears big and nice, instead of saying sqrroot u actually get a square root.
14. I found it on the difficulty level about 7/10. There were some challenging questions and some really nice ones, it was really just making sure you didn't slip up. Question 12 was probably the hardest part and when the examiner's report comes out we'll see that that's where everyone struggled so maybe they'll take that into account when drafting up the mark scheme.

my guess would be just below 60, maybe 58?
