One of the harder papers in the last few years IMO. ~85/100 raw I think. (Perhaps subtract some silly mistakes from below)
If I had to estimate....

10/10 MC
13/15 Q11 (embarrassing mistake on the log integration)
15/15 Q12
15/15 Q13
12/15 Q14 (Maybe 13, was d) a=3???)
11/15 Q15
10/15 Q16

Anybody care to guess B6 raw cutoff?
I got a = 4.5.

Fuark.. I won't even pass if that's true
well in 2011, someone who got a raw mark of 99/120 (or 82.5%) was given 89 as their exam mark.
So if this years paper was harder than the 2011 paper, then yeh i guess 82 is approximately right :)

Considering last years cut off was 83 and the exam was considerably easier, I highly doubt the cut off for this exam will be 82.
do u reckon it will be lower and higher (like i mean which exam was considerably easier lol) ? (and I'm just saying 82 so that people don't get false hope :) )

The shape of the tent was actually close to two trapeziums... So the trapezoidal rule gave a better estimate as it split the area into two trapeziums that would have been roughly the same as the actual shape of the tent.. If that makes sense lol

simpson rule employs rectangles, whilst trapezoidal employs trapeziums.
diagram shaped like a trapezium, thus trapeziums would better fit the area

damm haha, i said something like that, i said it uses trapeziums to calculate the area which is more accurate than simpsons rule in this case, and drew a tiny diagram
