Re: 2016 BOS Trial Results Nice, really boosted my confidence for the actual hsc exam.

That's the risk you took when you attended a very low ranked school to essentially guarantee you're rank 1 in all your subjects. And in the external you might think you had a 'bad day' but in reality you were never truly on the same level as all the students in the state due to the difficulty of...

Who here is 100% with their phys/chem/bio content?

Yeah please link it, can't find anything (do you mean the scaling report?). And from how you worded your answer above, I'll take it you mean there are only a few exceptional cases the gap has significantly decreased/increased. Though there's no way schools can simply alter all internal marks so...

Can you link where your claim is from? If you check http://www.boardofstudies.nsw.edu.au/hsc-results/moderation.html and scroll down to the 'relative difference (gaps)' they clearly say the relative gaps(after moderating) are similar to the relative gaps before moderation.

What?? You realise the difference between the ranks matter a lot right? CHeck the example on the bostes website where they explain this, the relative gaps between people are preserved after moderation. Otherwise you're saying schools only sending in the list of ranks without the marks would...

What/when is everyone's next exam?

gl everyone!!

According to this website 93-94 (out of 100) aligns to 97.

97 min, only half the people who get 97 will get a state rank. 95/96 = definitely not.

Here's the induction, part, I'll try the next part later...

???

What I got using that substitution...

Why don't you just think about the questions before posting? You look at what you have and what you want and see which equation(s) to use. There's a reason why people who don't do maths/general can still do HSC physics - there are no tricks involved in calculations. Maybe self learning isn't...

The radius + height above surface

Yes it is about the same, play around with atar calcs that give aggregates - though still slightly lower than advanced.

Re: HSC 2016 3U Marathon Nice, I did it the same way as well. Prove %5Cfrac%7Ba_1+a_2+a_3%7D%7B3%7D%5Cgeq%20%5Csqrt%5B3%5D%7Ba_1a_2a_3%7D Using 3U inequalities only . (You can't assume Cauchy's Inequality obviously)

Re: HSC Chemistry Marathon 2017 You would get 2/5, maybe 3 if the markers were very generous. You didn't make any reference to the extract except restating it, also your assessment completely contradicts the information you gave.

Re: HSC Chemistry Marathon 2017 Polylactic Acid (PLA) is different than most thermoplastic polymers in that it is derived from renewable resources like corn starch or sugar cane. Most plastics, by contrast, are derived from the distillation and polymerization of nonrenewable petroleum...
