umm so waht if part a is wrong and i used the wrong answer (5/2r) for the working out for part b and c?
that's exactly what i mean, they will give you 3/5 if your answer to a was wrong, but you used it to work correctly through parts b and c.
I won the GAT: 49/50/50.

I don't think this is true.
My maths teachers wife is an examiner, and I asked him today and he said its probably just a rumour. If they were willing to give out consequential marks then they surely must have had a meeting to discuss it and she would've been informed by now? So yeah sorry to break your bubble (to myself as well TT) but I highly doubt this is true.

I regret t inform you, but VCAA has strict regulations. In a two mark question there is one answer an one method mark, and consequential marks cannot be applied to answer marks. As a result i think it is highly unlikely 3/5 will be given to everyone who got the answer wrong. i guess about 1 or 2 max out of 5.

Hmm...

Suppose you had the most common incorrect answer - h = 5/2 r

part a = 0/2
part b = 1/1 --> correct substitution
part c = depends: if you use derivative = 0 and then say that r = 0 is max, then i'd say 1/2 only because h = 5/2 r gives you a positive quadratic, so right endpoint will be maximum. if you say right endpoint is maximum, then i'll say 2/2

Theoretically, the right endpoint doesn't exist though, as the radius must be <2.

True, yet the left endpoint wouldn't exist either as r>0 :S
We'll see what assessors rule

i said just before the right endpoint haha, because yeah, r cannot equal 2.

don't really care.  thankfully methods will be bottom 2.
