I think that's true, though assessment marks determine the "gap" between your HSC marks.

i heard they were planning to take out conics in the later years to come for extension 2 maths...and how is maths tested through multiple choice seriously...stupid idea.

STFU RAAQIM YOU SHIT CUNT 24/120 for trials and 6/40 for half yearly.

They are set out to award marks not take away marks. I heard somewhere they can also change the marking criteria if they find people are losing too many marks and thus remark and award more marks (don't know if this is what really happens). Btw nice sig Official, wonder if the guy is still...

28/84 i think is E2 and 43/120 is E2 or maybe E3.

hmm...wonder which school.

+1. In the marking guidelines, they don't require the statement, but the markers would always prefer a short brief statement e.g. "Therefore proven true by the principle of mathematical induction (or M.I.)"

Wasn't last year's cut off around 74/120? I don't know, don't think you can squeeze in but high E3? Depends, but judging from everyone's posts, the paper seemed to be easy... so the cut off might even increase.

If you do Extension 2 maths, how does the aligning/scaling change for us?

man, got like 60/84. Last year's E4 cut off was 57 despite it being extremely easy? I hope this year's is 53ish (anyone wanna estimate it?) so i can hit that E4 nicely.

There are many formulae for power, just use the formulae sheet provided.

you don't use any angle. P = Work/time, Work = PE + KE but KE = 0 as we assume the guy with his trolley are stationary and using the escalator. Therefore Work = PE = mgh where m = 115, g = 10, h = 9 and t = 25. Sub all into calculator and you get it 414W.

Yep! +1. And yes i got 414W for the belt thing. I found the paper much more difficult compared with other years. The "draw the laminated macrostructure" or whatever the question was like ....

i am fairly sure 2 was A as salt water contains ions which are free charge carriers which accelerate the rate of corrosion. Cold-rolled brass would not corrode from just the "stress factor" if it were in air therefore by placing it in a solution of electrolytes will accelerate the rate of...

Re: how to analyse a speech for distinctive voice? (willing to help out on other topi Tiffany please don't be desperate.

i hope so :D

+1. He probably wants to experience sex now seeing he is now a uni student.

Looks then personality. She has to decent smart i.e not a bimbo. Probably asian or my parents will smack me.

80? i think. A band 5 :(
