The overall performance of the cohort will determine scaling. But you definitely don't have to be first to be scaled well. If it is a poorly ranked school just be as close to first as you can.

Your going through a lot of trouble to make someone admit they are wrong and get a mark or two. If you know the truth that he is wrong, who cares about him or the mark. By trying to make him admit he is wrong makes you look very arrogant.

According to Table A3 of 2011, His Ext scaled better on average than all the sciences, economics and 2U maths.

What textbook do you use?

yes that makes sense because every equation with exponentials like OP has asked to show. thanks

Thought so. When I came across these that is what I though then I saw a Cambridge question asking to show that they intersect at x=1 and 0. So I should just sub the x values they give to 'show'?

How do you solve algebraically 2^{x}=1+2x-x^{2} besides trial and error?

Do you have maths in focus? If so do the first questions from each exercise. Doesn't get any easier than that. Even do development q's in cambridge.

Probability is a logical topic. Just take your time (when learning) and don't over complicate it. If your having trouble with HSC questions go back to basics in a simple textbook.

That's what you should do, just make sure your notes cover everything so that they will be all you need for study later.

Not necessarily. Sometimes when you write your own notes you leave out important stuff or details, and when you use them to study you could be missing out on something without even knowing. If you have someone else's quality, and detailed, notes and use them to answer past paper questions that...

"with a median Universities Admission Index (UAI) of 99.55 in 2004, and 99.20 in 2005 and 2006"

Assessment mark is based on ranks and external results of cohort. EDIT: 10 hrs study a day? are you sure its 10 hrs of effective studying?

Yep that's what it says on the site.

They are also saving 10c on each one...

He never said it was from scratch.

I was thinking the same thing. If you only do 2U and get 100 internal and external, then i can't see a reason not to be first. That's why there are a lot of ties?
