Bah, wasted 2 hours this afternooon by taking a nap. Looks like itll be a late nighter today

Sulfuric acid is still a strong acid, so its first ionisation goes to completion. The second stage is in equilibrium H₂SO₄ + H₂O ==> HSO₄^- + H₃O⁺ HSO₄^- + H₂O <==>...

Is there something wrong with your class sizes? The reason I ask is that for a school which you said is ranked 42 (or thereabouts), the english/phys/chem/2u/3u maths classes seems a little low.

You cant change your assessment rank.. and its this rank that determines your assessment mark (based on your cohort's HSC performance). Take for example my ext 1 maths marks from last year. I was ranked 16th and for a mark of 42/50. So the 42 wouldve been equivalent to the 16th highest exam mark...

You keep your own exam mark, no one will take that away from you. So if he does get 90 for the EXAM, then thats that. The exam mark that correlates to your assessment rank will form your assessment mark. These two are then averaged to get your HSC mark. So theres plenty of room for improvement.

You can gain some credit at uni for the distinction course you do. Its on a case by case basis though. Read the link for more info. http://distinction.nsw.edu.au/distinction/media/credit.pdf

I think you can get over 97 fantasia. I dont think your philosophy mark is high enough considering the average is 87 (rank 25th lets say).

creme of the crop ;) rank 13 for philo? god damn!

like? ;) get back to work you bludger!

None of the distinction courses are done at any universities. The philosophy material is delivered by the University of New England whilst comparitive literature and cosmology are delivered by Charles Sturt University. On a side note, they should make shirts saying "I survived cosmology"...

As long as you make your answer clear, (i think its just an X) then youll get the mark. Remember that teachers mark the HSC by hand unlike the competitions where a computer picks up the lead markings, so just use a blue/black pen as instructed.

3. see diagram 7. dx/dy = 1/2y x= (1/2)lny + C x = 0, y = 10 :. C = -(1/2)ln10 2x = lny - ln 10 2x + ln10 = lny y = e^{2x + ln10} = e^2x. e^ln10 =10e^2x

Id be more inclined to say mid 90s/120

1/(cosecx + cotx) = (cosecx - cotx)/(cosec²x - cot²x) = (cosecx - cotx)/([1 - cos²x]/sin²x) = cosecx - cotx In short, log rules are your friend :)

Dux at my school is given to the person with the highest UAI. But in terms of awards, we call the person who tops the most number of subjects, the 1st aggregate. Theres also 2nd and 3rd as well. Basically, the top 10 people in a subject get awarded points which are added up to determine who gets...

39, 76, 84 If we combined our results, wed be one good doctor :rolleyes: Ahh well, here comes commerce/science!

Im pretty happy with my final ranks, except for one subject. phys - 1/33 4u maths - 2/7 chem - 3/25 3u maths - 4/49 SOR I - 6/74 ... english (adv) - 24/56 my only motivation is the thought of having only 4 more hours of english testing for the rest of my life :D

:D got a HD as well

You can still apply. I know of people who did only 2unit maths and still get in :)
