Well that boosts my confidence a little. I'm looking at 19-20/20 for the mc. Just not sure on the last one as some people are saying it's A and some are saying C. I put C, so heres hoping.

Haha we got the exact same answers. I hope you're good at bio ahha. What kind of marking are you aiming for?

I also said C. But i can understand answer A as well. Punctuated equilibrium explains how the fossil record shows a species suddenly disappearing and being replaced by a different, but similar, species. So the fact that the record is 'incomplete' could support it but still don't quite get it.

Not sure but i've seen, 89 raw - 95 hsc (2010) 87 raw - 94 hsc (2010) Going by this, the cut off would be like 78 at lowest i'd imagine.

Re: 2011 HSC Biology Paper I did the same except i wrote data processor. Processor and logger the same thing or no? I didn't write anything about it not containing the actuall ambient temperature because it said hot, dry desert environment. (i'm shit at bio though, don't like it). I can't...

How well does biology scale? I would assume it's not that much of a difference? I went pretty average. Did hardly any study for bio though cause i don't like it. I don't need a high ATAR anyways for uni. Still i would like to have done okay in the exam. I reckon the communication part was...

Interested to know this as well. When i got the negative time for the cooling question i crossed it out at first (only 1 diagonal line, it's still clear). But then when i didn't know what else to do i just drew an arrow pointing to it and wrote "correct" in the hope i could get some marks for...

Re: Small numbers How much time did you guys spend on maths to be getting high 70s/80s? You don't even need any fingers to count the number of people that have done ex2 maths at my school in the last 2 years or the amount of E4s.

are you a wizard? thankyou.

Do you guys think i'd lose a mark for not making the statement, true for all n stuff, at the end of the math induction?

A decent 2 unit student could do it. f(x) = e^-x - 2e^-2x Had to find f '(x), the max turning point, the x and y intercepts, what the graph did as x approached infinity, and then graph it. That was for 8 marks. Pretty generous question 4.

It might depend where you stuffed up. You might have had to get the correct factorisation and put it equal to zero. How did you show it was a max if you got the wrong value? I don't know what happens on the graph, could lose a mark for not having the correct turning point. If your point doesn't...

Do you mean 5b. i)? k = -ln(3/5) = -(ln(3) - ln(5)) = ln(5) - ln(3) = ln(5/3)

Re: ffs... might get 48-55 I'm hoping i that my mark will get me an e4. It will be very close. After looking at the solutions i'm on 53/84 and i could possibly get 2 or 3 extra marks for some working in a few questions, depends on the marking. If i can get those extra marks, and if the cut off...

yes! That's 2 more, much needed, marks.

Re: Wow, fuck that Fuck this, i'm taking up an arts degree.

Re: Wow, fuck that Can't remember exactly but i remember the -40.

So wouldn't i get 2 marks then? Because i got the correct negative time but didn't subtract it from 10am?

Re: Wow, fuck that That's what i got, was rushing like crazy too. Had to do what i could see straight away of questions 7 so i could go back and fix up the math induction that i fuked up (got it out, just made a stupid mistake when factorising earlier).

Dammit i'm so angry with that. I just rewrote the equation with the numbers i used and got the same value. Used the negative time and ended up with 8:46. How many marks do you think i will get for getting the correct time, but not working out the time of day?
