I know it's impossible to judge, but based on how tricky you thought the papers were, how many marks from both would you say is a B? Would you say higher than 90 ish?

I'm sure I got above 90 for this. I'm lucky the part (b) for the trapezium was 5 as everyone in my class got 3.3 and I stupidly skipped the question. I basically got every question I answered correct except for the last 1 which I only got 2 marks on.
15b) I can just see the answer through proportional reasoning but I guess you could use similar triangles:
4x=1210+x
22) Work out the volume of the big cone and subtract the volume of the little cone. Again you will need to use similarity to work out the radius of the small cone.
