5. ### hsc english marking

For the HSC, are English papers marked by markers who know about the texts or just someone who may know it? If there's a possibility you can get a marker who doesn't know your text then is it fine to bullshit a few things? Also, do all papers from one school get sent to one marker? If so, is...
6. ### Atar estimate please <3

Would love to get 99 but not too sure whether it's possible (will definitely work hard to smash the hsc though). Also trial marks are a bit sad so will hope to do heaps better in the hsc. We can also get estimates from the school but I've heard that they're very dodgy School rank 2017: 10...
7. ### how are external marks calculated?

is it a raw mark based on how well you did in the exam, or is it a percentile, or a combination of both?
8. ### rectangular hyperbola question

The point P(2p, 2/p) lies on the rectangular hyperbole xy=4 The equation of the normal to H at P is y - 2/p = p2(x - 2p) The normal at P meets the hyperbola H again at the point Q. The midpoint of PQ is M. i) Find the coordinates of M ii) Find the cartesian equation of the locus of M as...
9. ### how to study for 4u???

Normally, I don't do any homework throughout the term and only do past papers starting maybe 1 or 2 weeks before an exam, yet I still do decent but obviously not super great. Now, I would like to do more regular study, but I'm just curious as to how everyone studies for 4u eg. do you do...

14. ### question about angle of inclination

Let's say we have to find the angle of inclination of a line with equation 2x + 3y + 11 = 0 so m = -2/3 and therefore tanx = -2/3 but that gives us the answer x= -34, and this negative angle really bugs me because I don't know what to do with it. Most of the time I just ignore the negative...

Question: The general form of a quadratic with zeroes x=2 and x=8 is y=a(x-2)(x-8). Find the equation of such a quadratic for which: a) the coefficient of x2 is 3 b) the constant term is -3 c) the y intercept is -16 d) the coefficient of x is 25 e) the vertex is (5,-12) f) the curve...
