There are plenty of pure and comp past papers on pmt. Advance info only says 'investigation involving graphs of functions which may involve using fundamental skills of algebra, trig or differentiation'....so not many hints there
how's everyone feeling for tomorrow
Good luck!
How did the exam go?

Might have been better than the last one. Did anyone else get the circle as (x+3)^2 + (y+3)^2 = 34 ??

As a percentage, I think it will be around 80% (perhaps slightly higher ~84).
It's obviously impossible to say as the percentage of people getting A* will go up this year, so the grade boundaries will be lowered, however paper 1 A* will probably be lower than 80, paper 2 significantly higher than 80, so today's paper 3 maybe a few percent higher than 80.
