I dun think you need that much essay practice for eco. If you know your content well enough and just include stats to support your arguments you should be fine.

Make sure you put 28 terms in the GP because its inclusive.

2008 is def the easiest :D

Imo Physics is easier and more interesting than chem. However, i think chem has been scaling higher in the last few years.

96.95 GO! scale me up :D

I would say 2u 2008 paper was the easiest paper I've done.

Imo, i think you describe the situations and stuff too much but you didn't include anything on how you FEEL. I reckon try to add more emotion into it. Fear, agony, hopelessness etc. "This place was so strange to me. Creatures would gather and press themselves against the glass – banging...

question 27 \frac{d\theta }{dt}=0.1 r/s A = \frac{1}{2}AB sin C A = \frac{1}{2}(10)(12) sin C A = 60 sin C \frac{dA}{d\theta } = 60 cos C \frac{dA}{dt}= \frac{d\theta }{dt}.\frac{dA}{d\theta } = 0.1 \times 60 cos C when C = \frac{\pi}{3} = 0.1 \times 60 cos \frac{\pi}{3} =...

question 22 dr/dt = dv/dt x dr/dv dv/dt = 4 so we need to find dr/dv B/h = 10/8 B = 5h/4 V = 1/3.B^2H but B = 5h/4 V = 1/3.(5h/4)^2.h = 1/3.(25h^2/16).h = (25h^3)/48 dv/dr = (75h^2)/48 dr/dt = dv/dt x dr/dv = 4 x 48/(75h^2) when h =4 = 4 x...

2. A factory is expanding yearly and produces 250 vehicles in the 1st year. In each successive year it increases the output by 75 cars. (a) How many cars are produced in the 12th year? Answer: 1075 (b) How many cars are produced altogether in the first 25 years? Answer: 28,750 (c) In...

1b) S10 = n/2[2a + (n-1)d] = 10/2 [2(4.9)+9(2.45) = 5 (9.8 + 22.05) = 159.25

we need to find dx/dt (rate the water level is changing) dx/dt = dV/dt x dx/dV we know dV/dt = 25 cm^3/s and that V = 30x + x^3 dV/dx = 30 + 3x^2 dx/dV = 1/(30+3x^2) therefore dx/dt = 25 x 1/(30+3x^2) where x = 5 therefore dx/dt = 0.238

i got 48.5 too..

first you have the specimen topic by topic questions then at the end of the module, PAST HSC QUESTIONS 2001-2003 and after that its the 2004-2008 past papers

yea. its out and the new ones have topic by topic questions and paper by paper =]

it would be better if you included your rank.

Like fortify said, I would seriously try to get a tutor or self learn and see how it goes. If that fails, maybe drop it. 10 units a bit risky imo.

umm.. no. velocity is not constant. It starts off at a constant rate and changes every second (could be due to gravity/air resistance etc). I'm not that gud at explaining but here goes... ok..velocity is the speed at which something is moving. when u throw a ball up, it goes up, slows down...

9) its projected at 30m/s (starts off at 30m/s) and decelerates at 10m/s^2 (slows down 10m/s every second). so the equation for the velocity should be 30-10t where t is the number of seconds. b) and to find the equation of h, it is asking for the equation of displacement. hence u integrate...
