Yeh, agree with most. First six questions were pretty easy, but then last page was a nightmare. Probably the hardest exam imo over the last few years - never seen a test that has three consequtive hard questions like this.

I'm just hope I can get a good B, if I don't scrape an A. But thats relying on the grade boundaries. Hopefully everyone has done rubbish on the last few questions and they to put the grade boudaries down!!
Yeah, the only thing I'm hoping is that the rest of country found it hard too! *Cries*

I hope its something stupid like half marks for an A.
2. Well everything I did I got 100% right, but my school cocked up and finished the exam 10 minutes early!

I never quite finish c2/c3/etc exams in the time period, but because of the 10 minutes lost I think I lost about 20 marks just from not getting onto the questions.

I looked at them and I knew exactly how to answer all of them as well, ffs!
3. Did anyone get the very last question about finding the range of k? I got confused! I thought that maybe as the equation was 4cos(whatever..) then for there to be solutions, the k + root 3 minus 1 or whatever it was must be between 4 and -4.. therefore for there to be no solutions I said the expression with the k in it must be greater than four or less than -4.. Anyone else do that?! Man I hope it's right..
DAMN b^2 - 4ac = 0 for the one solution to the stationary point. gah gah gah! I totaly forgot about it! Nightmare..
4. k was greater than root 4 +1
k was less than root 4 -1

not sure if they are right.
5. the paper is crap......
6. Found it easy until the last questions, in which i then died. Was by far the hardest C3 test and did all past papers. Think the grade boundary is usually 80%, so can get upto 14/15 wrong! Also thought there was a missprint in that question. Least you can retake...
7. yea....hardest C3 test. i did all the solomon papers n pastpapers! argh
8. k=2 and x=-1 if I remember properly for all those who struggled with Q7.

Anyone remember what Q8 was? Got a copy of the paper? Want to see how long it would take me to do the last Qs after where I was stopped

For the stationary point question, as far as I know, k was 2 and the actual point was (-1,-e^-2).

Having now checked this on graph software (the original graph with k=2 was y=(xe^2x)/(x+2)) I think I was right, how I got there though I can't remember

Worst. c3 paper. ever.
Got that too. I don't know how the b2 - 4ac trick came to me, but it did.

k was greater than root 4 +1
k was less than root 4 -1
Was that for the final question? I got something like that, but I might have gotten root 3, can't remember.

What was it? I didn't notice.

I think it was prove

you then had to evaluate 4cos(82.5)cos(52.5) exactly, find theta when and find the set of values of k for which has no solutions.

i *think* that's it.

The question 7 part i. Couldn't see how to get "+k", but could get "-x".
13. right..normally we need 58/72 to get an A....wht mark do u reckon we need to get an A?///
15. When do you think the paper and markscheme will come on the OCR site?

I can't see the markscheme being put up until results are out.

I thought that was one of the easiest questions on the paper!! lol. Although a fluffed the rest of the back page. Probably pick up a method mark here and therefore.

The one I was confused was about the integral one. It said, "show that can be written as . How do you that? I mean, easy to work out if it said show it as but stupid damn .

I'm really praying that everyone (or most) dodged the last page up so the grade boundaries go tumbling down.
18. I hope my AQA CORE 3 next week is'nt as hard *screams*

Shall we all just pray you don't have an English exam?!
