There isn't much of a difference between Standard and Advanced. Firstly, they share the same area of study. On top of that, the method for learning each module is almost exactly the same, you go through the rubric, do a few boring sheets to aid with your understanding, read and analyse your text...

The HSC scales people in your cohort by taking the very top scorer and the lowest scorer and spreading everyone out in between, what your teachers mean by working together is that people in the middle will have their marks skewed so if they help the people at the very bottom, it will reduce the...

I had the same lineup (2) as you and I have a close friend who does Biology and Economics. If you were to choose between them then, I can tell you what I know. Both Biology and Economics and a lot of content and memorizing to do, however, economics is more conceptual and easier to get your head...

The radical symbol (√) is just square root i.e. to the power of 1/2. In the complex field, √-1, its just i, otherwise i.e. in the real number field, it is impossible to square root negative numbers, hence we write no solution. As for -√1, its -i, much like 1 and -1. In reality, we use i was...

Some school will make you do the 2U test just in case you decide to drop, you should be getting 100% or at least 90% on a really bad day. As for 3U, you should be getting minimum 70%, it counts as 2 units if you end up with 4U at the very end. And you need at least 60% for 4U tests. There was...

If you were asking for roots of UNITY (meaning z^n=1) then you wouldn't have to apply that formula. Its more of a polynomial thing.

You should use more brackets to make things clearer but for these questions remember how sec, cosec and cot are the reciprocals of sin, cos and tan respectively and you treat them as powers of -1. As for everything else remember your basic and trigonometric differentiation techniques. As for ln...
