Does anyone have a copy of the exam paper?

He's doing history extension, there is no way that he would be dropping ancient. And yes, as WildestDreams said, do the subject you enjoy most

93-99.95, since you're first in all your subjects

For weaknesses, I do a crap ton of past papers/practice questions on a particular topic and then its pretty much becomes easy (in a scrap book). I believe notes aren't needed in maths because its just concepts.

What I like to do is do past papers and whenever I make a silly mistake, I write it down on a notepad. This notepad has been constantly filled since the beginning this year and before an exam I would just memorise the precautions for these mistakes. E.g. Always state units when doing measurements.

Yes its possible.

why everybody gotta be hostile all of a sudden :(

yes

You use implicit in conics to derive equations of tangents and normals to hyperbolas or ellipses.

Don't forget the reasoning!!!

This is a technique in extension 2, keep in mind there are techniques to solve this in extension 1, I have demonstrated how to do it above :D

P(x)=−x^3 + x^2 + 5x + 3 P(x)=−(x^3 - x^2 - 5x - 3) Factors of the constant term include: 1, -1, 3, -3 Test for x= 1, -1, 3, -3 P(1)=−1^3 + 1^2 + 5(1) + 3 P(1)=8 Since P(1) is not 0, it is not a zero. P(-1)= -(-1)^3 + (-1)^2 +5(-1) + 3 P(-1)= 0 Since P(1)=0, x=1 is a zero. Now you just...

In extension 2, if a polynomial has a double root, this root is also true for its first derivative, if it has a triple root, this root is true for its first and second derivative and so on. But keep in mind, you can only use this in extension 2.

I believe its under polynomials.

75, make sure you bring English up. At this rate it's dragging your atar down like nuts.

You don't have any prerequisite subjects for Medicine (except Standard English as a minimum level of English), although it is stated by UNSW that Chemistry may be useful.
