I remember those now. The best thing to do is to buy a Casio fx-991ES calculator if you don't use one already. It can find the numerical solutions to cubics allowing you to get the roots easily.

Doe anybody know whether or not one can sketch Polar coordinates with the fx 9750? If so, how?
On graph, press F3(type), then F2(r=), then just put in the equation. Make sure you change back to y= when you do any integration or differentiation (even for a polar equation) otherwise it'll give you something else.
I don't know how anybody could survive without a graphing calculator in any A2 maths exam tbh.

Cheers! I have an fx991 so will use that for integration/differentiation if needs be. Thus far I've only used my graphic calculator in C3 but I think it might come into use tomorrow!
2015 is quite brutal, someone in my class was determined to finish it in a mock, took him 3 hours...
high boundaries too
Most of the questions were alright I thought, just a few parts early on such as 4(iii) and 5(ii) which are easy to lose time on by doing them via an inefficient method. January 2012 is probably one of the hardest past papers. That one was 49/72 for an A!

Might just be me being weird but I actually got a fair few more marks on the Jan 12 paper than June 15
