BIG-WILLY: Take it easy mate! Not every comment is necessarily a sarcastic one- I surely didn't intend to be sarcastic; my comment was 100% genuine.
No offence but don't look *too* deeply into the posts, 'cause a lot of times, what one writes and actually is saying can be interpreted in a totally different slant by another, as eviidenced here. My general rule is that most ppl are genuinely here to help others and/or are grateful to those who do.
(<--- no sarcasm here ok?)
Anyway, the guy topping 4u at my school is an Australian Maths Olympian and is 'apparently' the best Australian mathematician under-21 (don't quote me on it though...).
If he doesn't top the 4u paper this year, a lot of people will be suprised...and like fatmuscle said, they make our 4u papers hard to challenge even him (well he never gets 100% in the papers), so as you can imagine my upcoming 4u trial is no doubt gonna be a bitch
