My friend last year got a state rank last year and she said she made a silly somewhere... hmmm

yeah :( Does it always have to be 70/70 for any state rank?

Oh that's awesome. I thought it'd still be out of 50 for me. feels so depressing that state rank is gone :(

awww :( How was 4U?

hmmmm, when you get 99 in ext1, is that 50/50? or 49/50?

aaaaah ouch. I know how that feels. In trials, I never got full marks for Q11. I lost my mark because I made a little silly in value of r AND my circle geo proof was very long and I fear some sort of mistake with lengths names being swapped. So I'm guessing around 67-69, what do you think that...

I'm expecting 68-69/70 Maybe 67/70 :( Maybe not... What about you?

hmmm... Yeah sillies dropped my mx2 mark to 80s hahaha for mx1, maybe about 1-3 marks gone all together :( [I saw carrots solutions] probably no state rank

Re: HSC 2013 2U Marathon Excuse me? From what you just said, you sound like an irrational caveman just roaring out of his cave claiming everything to be 'scum' when you clearly don't see anything. You lack manners and are being very irresponsible, this is a marathon. Not a place to argue, I'm...

Re: HSC 2013 2U Marathon You clearly cannot do my questions and complain about them. Makes you worse than scum does it not? If you cannot do my 'scum' questions, I suggest you ask for help rather than complaining because the most scummiest scum is the scum who complains about scum.

Re: HSC 2013 2U Marathon Sometimes, I guess the scums need some feeding.

Re: HSC 2013 2U Marathon Bumping for more exposure in case anyone didn't see.

I would recommend you to show one more step: Showing the integral in the form 1/(a^2+x^2) before integrating.
