It could be about both, my trials (CSSA) had both in one question hahah... ha...

I reckon it will be edison vs westinghouse, i dont think they asked that in ages

I feel like the marking will be very anal just to differentiate the top of the top regardless, state rank will be pretty damn high...

I think the reasoning was that 1 could be added on the right side so that it can be the equality sign/and inequality sign, because n and k differ at least 1, where n is greater or equal to k and also n,k are integers and then the equality sign disappears because you took out 3/4 But i think...

Hopefully, integration last question much like 2003 and 2010!

yeah you are allowed to use it but its heavily looked down upon apparently...

You might have to also consider the fact that last year's last question wasn't all too difficult compared to other years... So that could also have affected the cut off to being slightly higher?

Re: HSC Physics Marathon 2014 is it just v=(tBiL)/m subbing in all the values, 0.5m/s moving to the left?

Seeing as chemistry has more repliers, I'll post up here As the title goes... would anyone know the moderation (general) of option topics for not only chemistry but also physics and biology?

Yeah, defs HSC will be harder not only in the content but also in the marking criteria. I nearly full marked both 3u and 4u in CSSA but i know i wont come close to getting a 90 raw in actual HSC tests

i forgot the reason my teacher told me, but esp in mechanics (resisted motion) we take into account direction and hence we do the absolute value thingo this reason could be wrong, meh.

it is the perpendicular bisector of (1,0) and (3,0) i.e x=2 and shaded on the right side of it

beat me to it HAHA

uhm to avoid the undefined answer use absolute value sign for ln(x-2). i.e. ln(|x-2|)

I guess my best advice would be: always to revise and touch up on math every now and then. You should do this not to lose touch with your application of knowledge of math to a question. It would have been preferred that you have minimised your silly mistake by end of year 11 or start of year...
