Trick would have been to recognise it as an exponential growth. If you think about it, the original salt concentration in the vessel is 25/100 = 0.25 grams per litre. As you add a 2g/L and remove the equivalent, the concentration in the vessel will approach 2g/L. So the amount of salt at any...

Obviously we're studying everything LMAO. You'd be a fool not to. Wouldn't hurt to predict though.

hmmm should be ok. Just let this be a lesson to read the instructions...

What does everyone think is in this years paper? Personally, I have a feeling they're going Finance + Global for the extended response.

I smell Medentry...

Same as you, in that order lol. Srsly I wouldn't mind UWS. Duno why people dis it so much.

G luck with Umat next week ;)

Add to that that some people are reluctant to apply to new courses at universities. Usually when a course is introduced to a university, certain aspects of the faculty are unorganised. But that's just a generalisation.

Don't think its thats low. I'd think about 86-87. But tbh not really sure.

Um. My method does acknowledge the fact that you can have all those different possibilities. If it didn't, I would've multiplied by 1 instead of 9C5. I chose all the possible combinations of 5 from the 9 places. I dno how ur thinking about it. But that includes scenarios such as OOOOOEEEE...

You have 5 odd numbers. Now since they can only be arranged in the order 1,3,5,7,9; then you select 5 places for the 9 [i.e. 9C5]. Now theres 4 remaining spots for the even numbers. SInce they dont have to be in any order, they can be arranged in 4! ways. So the solution: = 9C5 x 4! = 3024

Thats how it is. The idea is that they want everyone to atleast have a go. But at the same time, the last 15 minutes is where everyones trying to finish the paper so they want it to be quiet.

Maths ext 1 closely followed by business studies.

18-25 November 2009 for the main round interviews 6-7 January 2010 for the final round interviews Edit: Good luck :haha:

Its a matter of supply for demand.

They've changed it to november lol. This post was in July, before they anounced the change I think.

Lol. As much as I'd like to think so, I really doubt it. I think they're just trying to help everyone with the application process and don't want people to miss out.

geez, thanks for being so insightful ACER :mad1:

+1. Tbh I agree with the article. Certain things could really affect a bright persons performance in the HSC. A non-educated background could be a start.
