Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016

Using trig, the shortest distance = 257.12sin70 = 242?
I used the cosine rule, don't think i got that one right

I stored some answers on my calculator:

137, 257, 357, 266, 59.3, 119, -1.58,

324, 256 - my values for n and k
I got n=9 and k=4

3. [QUOTE=9clpc9;65340709]I don't remember exactly what I got as my answers but it looks familiar! I got the same for 6b and 8

Hi, yeah can I get pics of the question paper please?[/QUOTE]

I got the same, I thought it was an alright paper. What did everyone get for the last question? I only remember the radius was 5

(x+3)^2 + (y-2)^2 = 25

It could have went a lot better

Thanks!
8. I did X/sin110 = 200/sin40 too??
9. for q4 i got 242 and 266

Yeah i was convinced the question asked on a bearing of 30 not 40.

Like why does my brain do this to me, the number 30 appears no where in that question? -_-

11. Grade boundary predictions for an A?
I think 61
12. anyone have any unofficial mark schemes?

I got 79 UMS when I first sat C2 and I got 59 raw marks. I wouldn't be surprised if it was around 57-59 tbh. If I hadn't of done C2 before I would have seriously struggled with that paper. For instance a few years ago question one of this years paper came up as a question 6or7 and it was worth around 8 marks (may have had a few more terms in the integration though)!

Lets all hope the grade boundary then for an A is 57.
15. How did you answer the last question?

16. Answer of 5i and 5ii? Hearing a lot of variation

I think I must've made a mistake, I got the centre to be (-3.14,2) but I had done length of a line for centre to each of the given points that lay on the circle then set them equal to eachother cos they're both radius's and I used that to find a (centre co ord for X) then subbed everything into (X-a)^2 + (y-b))^2 = r^2 to get r^2 and then a general equation from there
19. Thanks:-) I did it completely differently and I know I its wrong- I used the two points they gave me to work out a gradient and worked out an equation from that... do you reckon I'd get any partial credit for that?

I'm sure you'll have picked up some marks for it yeah!! How did you find the rest of it 😁
