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

Yeah I do. Not sure how I can send it though?

It will technically be at least an A as 60/75 is 80% (and we can assume grades will definitely not be scaled down) but it's pretty **** that getting an A* now is going to be very hard. Even looking at past papers any of them would never require you to form an equation like qu6. I'm just ranting now������

They flipping better scale the marks up and grade boundaries down cause it was so difficult from 6-8! Think I got 1-5 all right but lost a lot of marks on the back page I fear bricking it for C4 now!!!!!😭😭😭😭😭

How did u do question 4? I know I've got 4/5 marks but I've messed up somewhere as I kept getting 0

yeah I did at first too but the reason is because some of the area is under the curve and thus will give you a negative number The answer is 8 as the area between pi and o for one of the curves is 2. All the areas are the same so you do 4 (as there was 4 parts of the curve essentially) 4x2 gives you an area of 8!

Yeah damn I hope I get some marks as my method was correct. I'd also like to see people method for 8(b) if anyone got it correct

Yeah I'm pretty certain I got 61-62 overall. Does anyone know how much marks will be scaled up?

You take out a factor of 4/3! Then integrate 1/1-sin^2 which you change to 1/cos^2 and intgrate cos^2! I'm not sure how much they will scale them but hoping it will be big step up from previous years due to the difficulty

aye that is what i did as well.
For question 7, do you think it was enough to make logical statments for why it was always positive ie in 7.i, X^2 is > X where X^2 is always gives a positive value thus result is always positive?

EDIT: if not then sayanora A* 'casue thats 7 marks down the *****er already( plus i messed up the newton-raphson bullcrap up but i think everything else is okay)

See the thing is for question 7, it makes sense to all of us but i don't think thats what the examiners will be looking for, I did the same as you

I didn't get 7 but I would say that will get some marks if not all yeah!!

hmm, question 7(i) was worth 4 marks which is alot just for completing the square and a statement so hopefully they will credit our way as well. I mean they cant argue with the facts.

Please !! Really wanna go over the paper again
15. For partial fractions question i got the wrong remainder (x^2 instead of x^2 -1) and therefore the rest of the question i did wrong. (A/x and b/x^2) resulting in simultaneous equations. Would i be able to get any marks out of 10 for follow through?

16. Ignore my random working out🙄

17. What were the marks for the last few questıons? It got cut off

6. 6 marks
7i. 4 marks
ii. 7 marks
8ai. 3 marks
ii. 6 marks
8b. 5 marks
20. Well after looking at this again, I know I've done badly now. What was the boundary for an A* last year? Whats the lowest its ever been for an A* as well. This paper was definitely harder than any other c3 paper I've ever done
