1. General consensus seems it was hard and last year we all thought it was good - calling a rough estimate that 60/72 will be 80 UMS, last year was 65.
2. All I can hope for is to get 3/8 marks for q11 and some easy marks for q10iv

How did everyone find the C1 exam? Question 11 & 9 were pretty hard....
3. What in the bloomin hell was that paper?

I've been getting solid A's for the previous past papers (70/72 for 2015 paper) but this paper hit me hard. I wasn't the only one to find it difficult so hopefully the grade boundaries are lower or that c2 and s1 are bloody generous. :/
4. if anyone manages to get the whole paper again so we can go through it properly lol too impatient to wait for the results in August
5. I got 27 for the last question! What did people get for the other equation for the tangent to the circle?
6. (Original post by luketidley)
circles also do not come up on c1, geometry of a circle is a topic on c2! The topics for c1 are;
surds and indices,
quadratic functions, equations, graphs and transformations,
coordinate geometry and straight lines,
polynomials and the binomial expansion,
and differentiation!

These are on my course and i'm doing wjec.
ocr 2016 c1 q10 circles!!!!!
7. Hardest paper out gosh !
8. Yes! I got 27 as well hope we're both right.
9. Please does any one remember what they got for the equation of a tangent ?
10. (Original post by Skipper12345)
I got that k is less that -7.5
It is wrong as if you use k as -5 or -6 it will not intersect the curve, I checked it at the end.

2x if I remember correctly?
12. (Original post by stevenjo98)
I think most people got that answer
I got k is less than -2 and greater than 5? And many others got that as well

i got that as well if that means anything

Me too.
Yes! I got 27 as well hope we're both right.
Many people including myself also got 27.
16. Does anyone remember the actual last question though?
17. (Original post by Jakewww)
2x if I remember correctly?
2x was defo the gradient however you had to find the y value where the circle intercepted so you could plug the point into the equation of a line?

I got something like y=2x+3+2root6
18. Can anybody remember the indices questions? I remember the first one was (2^5 divided by 2^7) but there was something else in that question.

Also - what about the 2nd question, I got -¼+or-¾root5
19. For the question about the circle being wholly inside the other, did anyone else get 0<r<√45 - 5?
Most people got 0<r<2, but I thought that this may not be right

I'm pretty sure I got that as well on question 2
