do it online on Tuesday 29th of July, free registration
nothing prestigous, but good for the fun of it. Answer everything right and get to go to footscray campus for a competition, there's a few little prizes here and there, top prize is a scholarship at School of Computer Science and Mathematics [lol :P]
but do it for the good fun. I did it last year =] they bring some fresh materials to that aren't as boring as school work.
DO IT! and register soon. it closes a day before the competition.
ps, i just remembered, the finals is on the open day. but that's okay, do it for the fun anyways xD

The prizes are awesome though. I got the top prize which was a $250 voucher for Angus & Robertson. They didn't give out scholarships back then =(.

I think the $250 Voucher is worth more than a scholarship at VU :P

Hmm it is far from my place too, but I think I'll be able to go. We need to bring the invitation letter right? Still, the invitation letter is addressed to 'Student'... so I wonder how they will know who we are.
DODGY
its vic uni.
let's hope they will know who we are... haha.
but that's not to worry, I don't think VU really cares who the winners are, at the end of the day, the winners would have enough merits behind them to actually win the PSC, so lol~!

I liked that, I actually got how to set up the question :P
But 4 and 5, no idea how you would do it. Apart from maybe factor question 5 as first step :P And maybe make a all over 1 denominator. I dunno
