Haha, my friend did that as well. And yes, it'll be fine :)

You don't have to, but things like, reports from the Bureau of Crime Statistics and Research is something that could be considered to include - which are received positively by markers.

Not the first time it's been said hahaha.

I find World Order probably the easiest haha (Although you kinda have to have an interest in it already). PM me and I'll send through some things that may help you.

Family and World Order. You?

I have prepared a few essays for each option - but there is no way I'm memorising them. Much to risky. Know the content but write a few practice essays and prepare essay plans.

I think your working is fine, but note that the geostationary orbit of 5 x 10^4 > orbital radius of 6000. So the only thing i'm wondering is that maybe your answer should be a negative value? Perhaps it might not make a difference.

Don't think we need induction here. We observe that 3(14n + 3) = 2(21n + 4) + 1 Since a multiple of 14n + 3 differs from a multiple of 21n + 4 by 1, we cannot have any positive integer greater than 1 simultaneously divide 14n + 3 and 21n + 4 . Hence the greatest common divisor of the...

Hahaha, i read the question wrong :(

Use Kepler's Law of Periods for both planets and equate the \frac{radius^3}{orbital period^2} of the two planets. As \frac{GM}{4\pi^2} is a constant, we can disregard this in this question. \frac{r_{Alif}^3}{T_{Alif}^2} = \frac{r_{Ba}^3}{T_{Ba}^2} = \frac{(4.00 \times 10^{11})^3}{(8.75...

These are the two supplied by the board from 2001 and 2002 HSCs. The options haven't changed and if it got a band 6 back then, it'll get one today. http://arc.boardofstudies.nsw.edu.au/standards-packs/SP01_15220/ - 2001 http://arc.boardofstudies.nsw.edu.au/standards-packs/SP02_15220/ - 2002...

I'd go about answering this question like this: Cepheids are intrinsic periodic variables. The period-luminosity relationship of a Cepheid Variable star allows the distance to a Cepheid to be calculated. By observing the star through spectral analysis over time, the type of Cepheid can be...

It can be in report format with absolutely no penalty. Confirmed by my teacher who is a HSC marker of 12 years.

Personally I think the recent papers haven't been nearly as hard as the mid-late 90's. Apart from 2008.

i) Find first derivative and stationary points - it'll fall out to the result needed. ii) Since stationary points are at x = +- √3/3, and A > 0 .'. f(√3/3) > 0. Sub in x = √3/3 into the equation for f(x), manipulate --> state that it must be greater than 0 since f(√3/3) is greater than 0. It...

Do the last 3 years papers, they tend to ask the whole syllabus in a 3 year cycle. Whatever they haven't tested in the last 3 years - high chance they will this year. Good luck!

Learn a topic, do a few past HSC questions on them that vary in difficulty and then hit trial papers (Sydney Boys & Grammer write nice papers - Ruse papers are quite easy) . When your HSC comes round - do HSC papers. Not as much in 3U as compared to 4 Unit, but hardly any schools write...

In the old format 70%(57-58/84) aligned to an E4. So I'd be saying around 49-50/70 in new format.

For which band?

I found it a bit harder than most past years - but still shouldn't have made the errors i did.
