The paper was no where near 2013 level. In 2013 it was hard from 13-16. In this Q15 was harder then usual but Q16 was standard. The rest was easier than usual. I estimate around 85 cut off
I found q16 to be harder. q15 I think I got full marks but the last question of the paper I definitely know I didn't get part i) and ii) fully

I agree, Q15 this year felt like the Q16 of previous years. Q16 of this year caught me off guard

All my answers were the same. However, for the second last question, rather than doing two integrals, I integrated x^r from 0 to 1, and then subtracted the triangle made by the straight line. Ended up with the same answer however much lesd working out
Subtracted the area of the triangle with a base of 1 - (r - 1 /r) And height one

Yep, I did the same! However, I ran out of time and didn't prove that 1+sqrt2 is a max - how many marks will I lose? Also I made An=0, is that fine?

Yeah, you can also do the triangle thing, that's fine.

Letting An = 0 should be fine. Not proving that 1+sqrt2 is a max will lose you at most 1 mark.

What would the scaled mark be for a raw mark of 99? And would that get a state ranking?

For the rate of change question, are we meant to have the negative in the answer like -365 leaves/day. I wrote decreasing at a rate of 365 leaves/day
