Those subjects don't align or scale very well though. OP, what was the highest mark in the standard trials?

Hi, I'd estimate a 87-90. Most of your ranks are pretty average.

So to increase the concentration of the chromate ion (CrO4 2-) you want the equilibrium to shift to the left. This can be done a multitude of ways, let's go through the options. adding: (A) Sodium nitrate --> this will increase the concentration of nitrate ions --> no effect on this...

Re: HSC 2013 4U Marathon haha any hints for this one? something to do with small angles?

Can someone explain this to me? There are quite a lot of theories regarding how the internals are calculated. Is this one correct: 2nd person at school gets 2nd highest external mark (exam) or would it depend on the difference between 1st and 2nd and the moderation occurs from the difference...

Would you write the exact values throughout the working?

Has the essay question been released? For eco you just support your arguments with graphs, statistics aren't as important but will differentiate you from other students. e.g. for monetary policy you should have showing of shifts in aggregate demand, like contractionary monetary policy interest...

I suggest finding someone elses, writing will take too much time and there isn't much of that left.. Hit the past papers and the unsure concepts.

You've got ages. Revise the 3 terms you've done and go through everything making sure you understand all the concepts, I suggest you retry your topic tests once you have revised and understand most of the content. If you cannot get the answer use the answers to help you. After this start...

Actual organisation that creates trial papers and papers for yr 10s, 11s etc.

Are you sure it's something wrong and that she hasn't just corrected the marking guidelines (ie from exam comittee) ? (I know for cssa physics some QUESTIONS had to be corrected, unsure about marking guidelines tho) Mind posting the question and answer you put down?

For me, before the Year 12 HSC Trials, I completed: - English- 1 paper (none for paper 2, just paper 1), mostly just prepared essays in non-exam conditions - Mathematics Extension 1- 6 papers - Mathematics Extension 2- 1 paper - Chemistry- 0 papers - Physics- 5 papers (still messed up :( ) -...

Was this for maths?

Re: HSC 2013 4U Marathon Not quite getting this. So does that mean this is wrong? (changing the places of < sign and = sign) \frac{1}{0!} + \frac{1}{1!} + \frac{1}{2!} + \frac{1}{3!} + \dots = 1 + 1 + \frac{1}{2} + \frac{1}{4} + \frac{1}{8} + \dots < 3

Re: HSC 2013 4U Marathon I i'm wondering, shouldn't this be <3? because that never reaches 3? Are you allowed to say =3?
