A tip for the future, if you ever need it. The y intercept for that line was +1 if you remember. So if it was on the negative side, there would be no way it could cut the y intercept on. If you get what I mean

how many marks do you think i'd drop for drawing the sketch (q8b) 9x-4x^3 the wrong way round but correct (3) coords?

Where does it say to write them separately

Explain that to me! is that because p^2-6p+1>0? So the intercept was +1?

-1 (or -2)

It was an inequality question fo at the end u end up with 2 answers.
U had to plot them on graph and the mn as it was more than zero and parabola was positive had to shade outer region and give your ineq

past boundaries - I would say anywhere between 58-64 for 80ums

yeah but isnt it A1 for shape, and A2 for coord

predicting grade boundaries is a guessing game. I don't think it was an easy paper but was probably standard for a recent session paper. Last couple of papers have been 64 and 63 for an A. I doubt it will be too far away from that.
