goodluck. your workload seems pretty reasonable which is good. I keep hearing this is a marathon not a sprint.

Sorry, my bad, I overlooked the substitution and thought you were just substituting in the modulus of z1 and z2. Seriously honest mistake of mine, nt trying to attack you in any way.

thankyou very much.

Awesome, can someone give me a quick estimate after first assessments. maths extension 1 - 12/40 maths extension 2 - 12/18 english advanced 10/130 economics 5/35 chemistry 2/45 school rank 25ish cheers

|z1-z2|^2 = |1-1|^2 I think that is a nonsense regardless

|z1 - z2| doesn't equal |z1|-|z2|. I don't think something is wrong with the question.

Cheers. No I don't go to Ruse. Just quick question to anyone, If you go to a high ranking school , lets say top 30 in the state, is it easier to estimate your ATAR from internal ranks as opposed to internal ranks from a school ranking 300?

48/55,000 lol. I think those odds would be absolutely laughed at by any community of people besides those on boredofstudies of which at least 48 people think that it will be them.

I'm not coming in saying "my goal is 99.95" like saying "my goal is to go for a run this afternoon," because it's not a boolean thing. I will (more than likely) get an ATAR that is reasonably high and I don't have this idea that it is 99.95 or nothing. It is a target that I am looking at more as...

With ATAR's out and now exactly a year until they are out again, it seems fitting to start my 99.95 journal (I was also inspired by the aero2146 thread). I do Chemistry, Economics, Advanced English and 3 + 4 unit Maths. So far these holidays I have been working on finishing my notes on...

YES I can see if people I know got b6 by name not just number. Is it tomorrow or today that it is published?

Just a quick question - I assume that the telegraph and the Sydney Morning Herald are the papers that list them. What do they lis? every person that gets a band six? seems titf. Also, what day would this be?

Re: HSC 2013 2U Marathon Okay my incompetence at using my calculator

Re: HSC 2013 2U Marathon Oh no I've got it now. My calculator was squaring it incorrectly

Re: HSC 2013 2U Marathon Yeah exactly.

Re: HSC 2013 2U Marathon Shit sorry. My calculator was giving me 2root5 squared as 10. My bad

Re: HSC 2013 2U Marathon I tried using the cosine rule for cos(90-alpha) in triangle apb but I'm getting (x^2 - 6)/4x

Re: HSC 2013 2U Marathon I'm pretty sure he/she means how many games do they have to play for their to be 99% chance they have won one of them
