what do you think about Spesh 2?

lol almost stuffed up qn 4 badly, forgot about the coefficient of friction... so had to fix things up so I think I might've got the acceleration wrong. 0.7 anyone?

WTF I GOT THE RELATED RATES QUESTION WRONG

I found this year much harder than the previous years. Probably due to exam pressure and the panic attack i got halfway through when my calcs batteries died (luckily i had 2 spare ones on me so it was able to last just until the end of the exam).

I've already noticed a few careless mistakes i've made so far, which is annoying; especially with negatives...

Hopefully looking at 74/80, but i'm quite certain careless mistakes will take me down to ~65

i got 0.2. but i'm not sure
is the angle 41.4 for the previous question?

Yeap 41.4

yeah a=.2 for me and same with the angle. last answer was 51.6, I'm pretty sure.

Oh crap, I added the friction rather than minused.

how do you get 51.6? i had no idea how to find the amount of whatever it is that flows out :S

you had to integrate the outflow between 0 and 10, the eqn was x/(1+t), and you had to sub in x with the function

[illuminati]

fml, that was the most tedious spesh exam i have ever done...

YAY i had a bit of a guess to do it this way

hopefully i can get 75+.. plus exam 1 yesterday which should be 40/40.. can i get 45+?

i'm pretty sure you can figure that out your self, if you reckon you only lose 5 marks and you want a study score that is 5 ss points from the maximum...

oh! that requires some thinking, and my brain was obviously not working properly. sigh.

boredsaint - definitely! even higher than 45 i suppose.

what do you guys think i could get if got 70/80, 39/40 and pretty high sac marks (ranked 2nd). 44? probably not i guess

Overall a hard exam, however not the hardest exam. It was full of tricks from previous VCAA exams that lots of students dropped marks on. If this was the first exam in the study design, it would be the hardest, but considering that most of the parts that you needed to 'think outside the box' were similar to past questions, it wasn't the hardest if you did the past exams and read the assessment report.

Here are a list of tricks I saw:
Finding the concentration (Q5a) - Exact same question as 2005 Exam 2 Q1a (even the same answer of x/(10+10t) LOL). Only 20% of the state got this right in 2005. The next part of the question where you had to find the differential equation was also the same.
Verifying x(t) by substitution (Q5 b?) -  Same idea as 2010 Exam 2 Q3a. 85% got 0 marks for this 3 mark question in 2010 and only 5% got the full 3 marks.
Finding the m1 and m2 (last part of Q4?) - Similar idea to 2007 Exam 2 Q3e. About 50% of the state got 0 marks for this 4 mark question in 2007 and only 14% got the full 4 marks.

There's probably more since I can't remember all the questions and haven't checked every past exam but those are the ones I saw.

Personally I managed to finish. But didn't have enough time to double-check multiple choice and according to iTute, I got 3 wrong already

[jane1234]

Is the itute answer correct for the dh/dt??
