    Scholarships (Co-op and others)

    Apply for every scholarship! every one you can. Uni's do not know what preference you want their scholarship etc, they just know that they want the best students, and if you are the best student they will offer you the scholarship, simple as that. Universities understand that students apply for...

    Is the BOS only interested in your rank from assessments in school?

    sorry, just for clarity, if there is equal first ranks, they average the two highest external marks, and they each receive that mark as their assessment mark?

    Is the BOS only interested in your rank from assessments in school?

    If two people rank equal first, do they both receive the highest mark in the test for their assessment rank? or a split between the two highest marks?

    Economics

    You need to be able to relate cause and effect basically. In so many of the topics that you study, Fiscal policy, Monetary policy, Balance of Payments, Exchange rates, there are just dichotomous effects and you basically need to understand, and explain the drawn out effect of a change within...

    A difficult geometry question.

    haha i cracked and looked up the answer. It is quite a nifty proof :) but quite long considering how simple the question seems.

    Re: HSC 2012 Chemistry Marathon 1. Explain why the equivalence point of a reaction doesn't necessarily result in the pH of the solution being 7 at that point. (2) 2. From this, write a balanced equation for an acid-base neutralisation reaction with a equivalence point of pH>7 and state the...

    A difficult geometry question.

    question to OP, is this possibly a proof by contradiction?

    A difficult geometry question.

    inafter, where did you prove that the constructed triangle was isoceles? the two bisected angles cannot be assumed to be same, because that's what we are trying to prove. I also have no idea how to prove it though :) haha but still trying

A variety of petrochemical feedstocks can be converted into ethanol. Biomass, containing cellulose is broken down into glucose monomers through using bacteria...

    Re: HSC 2012 Chemistry Marathon a) b) both of these steps increase the efficiency of the esterification reaction. The concentrated sulfuric acid acts as a catalyst to reduce the activation energy for the reactants, and the refluxing process allows the reaction to occur at a higher...
