Yeah I'm resitting C2 as well. Chances are with this being a nice c1 paper that this c2 paper is gonna dick me over somehow. For some reason I just keep messing up on triangles on C2, and just make general mistakes throughout the paper. Need prep for next Wednesday definitely.
I'd defo look over the Jan 2014 paper which seems to have extreme versions of a number of the standard questions we're used to on C2.
You defo need a good knowledge of cosine rule rearrangement, angles and triangles so that would be a good one to look at.
Also a pretty intense arithmetic question where you have to simultaneously solve 2 sequences algebraically
Just to throw a quick tangent to this convo (no pun intended ) what do we think (if you're doing it), that the C2 paper will be like. On a resitting marathon of 1 & 2 after disappointments last year (did well on S1 though) and the past 3 C2 papers have been challenging. Would like another one of that mould, keeping the A boundary around the 55-56 mark.
I prefer c2 purely because I don't have to count mentally! I work so much quicker if I don't need to use my brain to count.
Last year was a little dodgy for c2, particularly for the last question if you didn't think of using pi r squared to find the area of red roses.
With regard to the questions, the simultaneous equations question in 5b of c1 today was virtually lifted from Edexcel C1 2015.
The boards seem to be robbing each others questions, so I would anticipate an applied AP or Gp such as a depreciating car or maybe a bank account with compound interest, an edexcel and aqa favorite. I strongly advise looking to other boards for c2!
