My Maths teacher said that he'd spoken to one of the exam writers over the weekend, and apparently people who did proper working through parts b and c of question 11 are mostly getting 3/5, consequential marks. This guy had marked ~40 papers when he told my teacher this, so provided you worked through parts b and c properly, you'll get the 3/5! :)
-
Probably the best news I've heard after today's dark day. :)
-
Woop Woop!!!!!
38/40 here I come :D :D :D
-
bad news for those of us that got it right. :'(

+1

Yeah, I got it all right too...thought I'd share the news anyway :)
EDIT: anyway, 40>38...a whole 2 marks difference :)
-
Really? That's quite unusual, because there are answer marks and method marks, but would be good news to those who couldn't get part a).
-
thank god
-
I wonder if that will raise the A+ cutoff...
-
It probably will, maybe 2 or 3 points higher than otherwise
-
I wonder if that will raise the A+ cutoff...
Definitely.
-
you made my day.
-
So we can expect the cutoff to be the same as last year?
-
I LOVE YA 38/40 here i come =P
-
u beauty VCAA
-
LOL we should still be angry!
-
i reckon maybe one less than last year
-
bad news for those of us that got it right. :'(
all class you are...
-
negative karma him
-
aw come on. surely if you'd got the question right you'd feel a little peeved. i'm only human.

tell me if you lost 12.5% of the paper because you could do one little section, you wouldn't be peeved.
-
YES!!
-
I would be, I'd be pissed as hell. But it's all about different perspectives. I'm sorry if I sound inconsiderate, but honestly, it's just how i feel.
-
Wow, this is the nicest thing VCAA has ever done :)
-
I FUCKING LOVE U MAN!!! LOVE!!!!!!!!
-
thank god man...iloveyou
-
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?
-
Nice work VCAA - good that you are being nice!
Although if you used h = 5/2 r, you'd get a positive quadratic in part b, so your derivative = 0 => r = 0 would be a local minimum actually
But all the same, glad that VCAA paid consequentials

lol, yeah this is what I did.
But then I said the max value of r would occur at the endpoint, just before r=2 lol...
-
Meh, this news will adversely affect my raw score, but either way I got 40/40. If my mark went down I'd have a right to be disappointed, but being upset because a large amount of people got extra marks would make me me feel animal, like the VCAA system has corrupted me.
And I can understand if I struggled with that one question, I'd feel cheated as well if I lost 5 marks for 1 mistake. Fair decision in the end.
-

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 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.
-
This is not true. --> No meeting yet so cannot be.
-
That's the shitest news i heard all day. now i'm fucked since i got 40, but hopefully that means i'll score higher for exam 2.
-
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.
-
THELIMZ, i hope your day has been brightened. MR JELLIF
-
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
-
hopefully your right .

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.
