y = sin^{-1}(\frac{2x - 1}{3}) $Using: $ \frac{d}{dx}[sin^{-1}(f(x))] = \frac{1}{\sqrt{1 - [f(x)]^2}} \times f'(x) \frac{dy}{dx} = \frac{1}{\sqrt{1 - (\frac{2x - 1}{3})^2}} \times \frac{2}{3} = \frac{3}{\sqrt{9 - 4x^2 + 4x - 1}} \times \frac{2}{3} = \frac{3}{\sqrt{8 + 4x - 4x^2}} \times...

Not good. I should catch up on sleep as i felt and still feeling exhausted throughout the whole of today unable to keep my eyes open. Do some things to get you motivated for the next period of studying, e.g. music, reflecting upon why you want to do well in the HSC etc.

I was joking LOL

Ask your teacher for some essay questions to get you started.

So many notes haha. I downloaded these here a while back and i think they're pretty useful for curve sketching. I forgot who uploaded them but credit goes to them. http://www.mediafire.com/?rivl13qdl6yjopt

Sounds good to me, the >5pm break sounds great haha. Remember to stay disciplined and stick to it!

I think one hour is too quick to be having breaks. Once you've reached an hour of solid study, you probably have built up momentum whilst you're doing your work and stopping at this point wouldn't be very helpful. But, whatever works for each person.

+ the occasional feast of humans.

7-7:30am: Breakfast 7:30am - 12pm: Standard English 12-1:30pm: Break/Lunch 1:30pm-6:30pm: 4U Mathematics 6:30pm - 7pm: Dinner 7pm - 11pm: Biology Sleep Repeat everyday switching up the subjects and you have the perfect timetable. .. Crap timetable aside, you should try make one yourself that...

I made a timetable a while back and followed it for about a week or two. I got a LOT of work done, but i eventually slipped out of it lol. Hoping to stick to this new timetable and continue on throughout the year :)

Thanks for the reminder, should get to making one

sorry im busy on monday :(

Drawing pad.

Re: HSC 2012 Chemistry Marathon *revive*

There's only a list based on English and maths results so doesn't include all distinguished achievers. http://bettereducation.com.au/Results/Hsc1Page.aspx

Will try my best haha. Thanks for the advice :)

170~180 based on last years results. However teachers say our cohort this year is much stronger at the maths and sciences than the last.

English: 15/20 Overall ranked 6th, satisfied. Math 3U: 57/60 Overall ranked 3rd, silly mistakes :( Math 4U: 37/40 Overall ranked 2nd, again silly mistakes and misreading questions.. Chemistry: 47/50 Ranked 3rd in this test, don't know overall. Marking criteria was tough.. Physics: 46/50...

I"ve heard good things about SIGI Learners.
