yh i agree, but depending on the stats/mech paper it could potentially be lower. This paper was definitely tougher than last years. if i had to put a guess to it, i would honestly say around 98/160 for an A

did anyone do the proofing question at the end? if so, how did you do it?
Sub in n=2x and n=2x+1 (even and odd numbers) then take a factor of 8 out and show it’s not an integer solution e.g. (2x)^3+2 = 8x^3 + 2 = 8(x^3 +2/8). At least that’s what I did

for the proof you had to do n=2x^2 and n=2x^2 +1
it had to be a natural number, so not negative, hence it must be squared to ensure it's positive

Well I divided n3+2 by 8. That would give n3/8 + 1/4. So I said that you add 1/4 in every value no matter what the value of n is and you get a rational number in the end. I’m not sure tho

I reckon A is like 70%. I meant the B would be 60% btw.
Bro you're just making **** up. Our paper was a lot easier than last years. Grade boundaries will likely go up

I said that it didn't take into account other factors that could affect the value of the car, such as mileage and damages to the car.

Not to mention that you probably did last years paper as a mock like 2-3 months ago so you had less knowledge so it probably felt harder for you
