I'd say that you're sitting on about a 90. Is it just trials to go for business?

88-90. Try to get top 20 in ext1 math, top 15 for 2u math and top 25 for english advanced! This should put you in the 92+ range.

88, try increasing that standard rank man!

I'd work on maths and english. At the moment I'd say you're sitting on a 84-87, if you get top 15 for english and top 10 for maths a 93+ if definitely possible.

I'd say 93-95 for both of you.

I think you should do two science (for med I suggest do phys/chem as my teacher mentioned that biology is mainly rote and uni biology isn't much different to hsc biology, he also mentioned how chem would be more useful in uni) and two humanity subjects (in your case for commerce, business...

how about maths? (2,3,4u)

bump, I heard from a retired hsc marker due to the exams being scanned pencil is now not allowed. can anyone confirm?

I have a question, for maths ext1 how come your school has only done 30% of their assessment tasks? did you do like 3 lots of 10%'s?

Re: HSC 2013 4U Marathon Which topic does this come under? Can we use facts such as Area of circle, arc length etc?

Re: HSC 2013 3U Marathon Thread Oh yep, I agree, "area" wasn't the correct word. Now your question: \int_0^{\frac{\pi}{2}} \cos^{4}x + \sin^4 x \ dx = \int_0^{\frac{\pi}{2}}\frac{1}{4} (1+cos2x)^2 + \frac{1}{4} (1-cos2x)^2 = \frac{1}{4}\int_0^{\frac{\pi}{2}} 3+cos4x = \frac{3pi}{8} how...

Re: HSC 2013 3U Marathon Thread Show that the equation lnx + x = 0 has a root between x=0.5 and x=1. yup this is correct, but I think it would be better if you subbed in f(0.5) and f(1) LOL sorry, idk why this quoting stuff isn't working... Edit: works now..

Re: HSC 2013 3U Marathon Thread @heroicpandas, was my answer correct for your question?

Re: HSC 2013 3U Marathon Thread Question: $Without evaluating the intergal,I = $\int_{\frac{1}{2}}^1 ln(x)dx,$ is it less or greater than zero? Negative as the "area" (not sure how else to put it, but the region there..) between 0.5 and 1 would be negative. Therefore less than zero...

85-92

97.5, needa increase some maths rankings!

Re: HSC 2013 4U Marathon How would you do this question? P is a point on the ellipse x^2 /a^2 + y^2 / b^2 =1 with a centre O. A line is drawn from O, parallel to the tangent to the ellipse at P and meets the ellipse at Q. Prove that the area of triangle OPQ is independent of the position P.

It's not too late, you still have over a week to prepare! You should fully read over your notes and practice writing english, business, modern and ancient essays. Also, try to do two past papers for each subject.

that's a huge aim.. i'd say at the moment: 75-80 atar

92-94
