Alright, i think its time peeps just shut the fuck up about the 'Cone Of Death' and focus on Part 2. :) :)
So what do your reckons gonna be on Part 2 of the exam??
-
The Pyramid of Death :D
-
My calculator and I will think of something to overthrow such an evil entity if it ever existed.
-
The Pyramid of Death :D
Oh my god. Do. Not. Jinx.
-
Pyramid of death wouldnt surprise me considering the things tasmania jones gets up to. however i hope theres going to be a lot less emphasis on just killing the majority with silly questions, and more of a spread from easy to difficult.
-
I CAN SEE IT NOW:
Tasmania Jones was scouring some Ancient Egyptian PYRAMID OF DEATH for treasure, when he stepped on a booby trap and the pyramid started filling with water at a rate of 5m^3/minute. Tasmania is inside a cylindrical chamber inscribed in the pyramid, with the base of the chamber lying on the same plane as the pyramid floor....
OHGOSH.

well if its anything to go by...the teachers at my school told us at our last methods class that the tech free will be hard this year, but the tech active will be easy, becuase everyone is doing CAS, with many being unfamiliar with the system...so who knows? could be an easy one :D
-
I think transition matrices, something to do with trig, probability..perhaps things unique solutions in MCQ

My teacher told me otherwise, cause with the addition of CAS, they can make exam 2 brutal, while new CAS material for paper 1 is supposed to be stated in the "sample", which held no useful information on exam 1 whatsoever-.-
-
I also have a feeling exam 2 will be easy. Hopefully it is like 08. :D
-
Not a prediction but i hope we get to predict how long Tasmania jones has left to live if sand if being poured into a cylinder within a pyramid at a rate of 1000g/sec....
Tasmania jones is lame.... his 'adventure' in the 06 exam was measuring his farm
-
Out of Exam 2 VCAA 2006-2009, which one is considered the hardest?

I wan't those questions. I haven't screwed one up as of yet :D
At least it gives you something to match the numbers up with haha...
@Souljette: I haven't done 09 yet, but i would say 2007 was the hardest. Best mark was 78/80.
-
@ JinXi, you do have a point, but you see there is also a possiblity of making it easy becuase all those who just moved into CAS will be unexperienced, so to make the paper accessible and preserve that bell curve it will probs be easier..
-
sketching graphs, trig:general equations , hybrid functions, matrices ; unique/infinity/no solution thing
-
I'll say
linear approximation
LOTS of probability (binomial especially)
Applied differentiation, with graph sketching and domain finding.
and of course Tasmania Jones unless they have, quite rightfully, fired that exam writer
-
I hope there's a probability question where it switches back and forth between binomial and normal and standard normal....
-
I'd love to have a Tasmania Jones question where he actually dies.
FIN

WHY?! :(

Well its actually not that uncommon.
-
True... I hate probability.
-

If I ever meet Tasmania Jones I am going to punch him in the face as punishment for his mathematical shenanigans.
Also, if you come across a Tasmania Jones question that you can't answer I reckon state that he survives or whatever because they wouldn't kill him off :)
-
just as like previous years.
general trig solutions
unique sol or infinite sol those bullshits
related rates for sure
extreme graphing
markov chains
ye its obvious
-
Eww related rates when given a CAS....argh, can never get my head around what they actually want...at least in the easier questions you can sorta fake it...

Hahahaha... they can kill him off and bring him back to life... with VCAA anything is impossible, just like a cone of death
-
Pyramid of death sounds interesting O.o
-
I hope the whole paper is probability :D

I hope the whole paper is probability :D
I like this very much

Haha i did an exam with a spy, i forgot her name victoria something... you had to figure out whether she got eaten by dogs or not... it was obvious they wernt going to let her get savagely mauled (this made me realise our answer of her getting eaten was wrong lol)
Just going by trends, VCAA 2007 Exam 1 was hard and thus had a low mean; VCAA 2007 end of year was hard and also had a low mean.
2008 and 2009 both nearly shared the same mean for both exam 1 and 2. Exam 1 had a higher mean (thus was easy) and Exam 2 had a higher mean also and thus was easy.
2006 is a slight exception, it had a slightly harder exam 1 than 2008-2009 but a slightly exam 2.... (this was the first year of the methods cas study design though so bugs are expected?)
If this trend is correct... we should be in for a hard end of year...

You speaky english?
-
Basically what i was saying was.... Years when there was a hard midyear, had a hard end of year too.
Look up the grade distributions and look at the means.
-
Methods has a mid year now? I hope i got a derived score... i didn't turn up
-
did i say midyear? haha its late...
Exam 1
-
I'm pretty sure the bloke in the vcaa office can't distinguish between a harder and easier exam. They don't change the exam based on how the cohort did :P
-
It being hard can either be good or bad depending on how strong of a student you are..
What would of got you a C+ in an easy exam (2009) would of gotten you a low B+ in a hard exam (2007) though if youre near the top this kind of screws with you (good thing im not)

I know they write the exams one year in advance but the correlation is there. Maybe one guy has lots more input into writing the exam than the others and he would logically write both. It might change from year to year which explains the fluctuations. Who knows? I'm shooting in the dark
-
Out of Exam 2 VCAA 2006-2009, which one is considered the hardest?
To me 2007 was hardest
2006 was easiest
2008 and 2009 were moderate
-
I hope we get a difficult exam. less than 50% and still a mark of a B will help alot of kids out :)

But getting 50% on a hard exam ... that's another story
-
Hopefully The make it really hard.. give a chance of scoring high to all those who did not get the Cone of death out..

Hmm that is true, but I think the kids who genuinely put in an effort will be able to answer all the questions, even if they do it really poorly. That way, if you have answered all the questions, albeit incorrectly, you are at a higher chance of beating the people who didn't try, who won't even be able to start on the questions.

True gives you a kind of "buffer" to make silly mistakes..
