Hsc 2009 bio exam How'd everyone go?? I think it was a pretty straight forward exam.. besides some multiple choice questions that were tricky :/ My options on genetics had big questions... 5 marks, 6 marks, and 7 marks consecutively :O! Question 14 about the punctuated...

Ah I guess, but then again it's recent and accordingly to my teacher, HSC asks questions about recent things that has occurred. :S Yep thats pretty high for Bio..good luck =].

My guess on the 8 marker? SWINE FLU!!!!! Probably something about control/management of swine flu etc.. something on the lines of that.

Bio isnt really good for scaling so probably really high.. 90+...

Hahaha lets dominate this exam :) I'm willing to answer any last minute questions if you pm me (:

nup its not linear

Wow BL man..I feel your pain. I made even more terrible mistakes :( I wish I could do the paper again

Lol I see..Just don't get too shocked when the HSC marks come out ^^

46/50? Im guessing

100 probably. What'd you get wrong?

hmm why is the cut-off for E4 seem so low from everyone's posts >.>. Its so low that everyone would get band 6's and barely any band 5s and 4s to give out..

Oh.. thats lame :( ...hope of getting 98 in both 4u and 3u is rare noww...=/

`SOOO DEPRESSSEDDDDDDDDDDDD I thought I did well....thought the test was easy until last bit of question 7..but I found over 8 marks worth of careless mistakes in question 1-4 T_T FML.. What would 72/84 be alligned to? 96%+??

What mark do you think you'll get? Hmm that was an alright exam.. probably got about 100ish/120. How'd everyone else go?

what paper is this from? looks very familiar

The assumption is z is a complex root and since P(Z) = 0, the conjugate of P(Z) is also zero..

Last years paper was easy so I have a bad feeling this years is gonna be hard..:/ good luck to all!

(ii) P is a point on the ellipse x^2/a^2+y^2/b^2=1 with centre O. A line drawn from O, parallel to the tangent to the ellipse at P, meets the ellipse at Q.Prrove that the area of the triangle OPQ is independent of the position of P.I've tried doing this proof for about half an hour now and I...

Yeah I know how to do that part, those are the parts before this question which I don't know how to do (not sure if they're related......i think so) Question: Let α, β be real numbers.Find, in its simplest form, the cubic equation whoseroots are α + β,αω + βω^−1, αω^2 + βω^−2.

Also proof for ellipse/hyperbola where the tangent/normal at a point P bisects the angle it makes with the two focus..(reflective property of ellipse/hyperbola)I hate this proof.. Anyone know an easy way to do it?
