In 2013, 75 raw became 90 according to https://rawmarks.info/mathematics/mathematics-advanced/ - hopefully that will be the case if ppl found our paper harder

I got 6 years were u meant to divide by 4

if they draw 80 000 a year for 6 years they only draw 240k, which is well below 1mil

Q16a

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

I'm a maths tutor. Here are my worked answers to Q16.

I'm a maths tutor. Here are my worked answers to Q16.

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.

One mark max and yes i made An = 0, thats fine

Any tuition centres upload full solutions yet?

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

[dontbeasavage]

the paper was 50/50

 

[abdulrahmanbhatti02]

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
