The 4U part of the forum is the only part I monitor.

Our trial will be on Thurs next week, except i'll miss it due to IOI and have to do it when i get back. I just want to ensure that no-one posts it on this site because i may see it.

Exactly, I make way too many careless errors. In fact I would prefer it even lower , say 25%, except then that would be getting a bit riduculas.

Yep, us in Maths 1 at Ruse were taught this in class.

Yeh, I''ll do it. Last time had 4 questions left with 30 mins and only 1 error in section 2, then screwed it from there. So should have got a medal.

Yeh, I was one of those guys who got a medal. I didn't have a map so instead of going to the lecture i originally put down i followed graham to crytography.

I agree it should be harder. Make the average less than 50%.

Wow, I thought us at Ruse had the most doing extension 2. What school are you from?

We have 4 classes - gives about 80, and not everyone who wanted to do 4 unit got to do it.

I went to crytography and it was reasonably interesting (although i missed the first part). My second lecture, a mathimatical problem a computer can never solve, was extremely interesting and has major implications far beyond computer theory. There was one error in the guys proof, but i only...

Hey, if you were put forward as one of the top guns and are going to the Talented Students Day I want to meet you. I should be easy to find as I am getting a Mathsearch medal, and if its anything like last year they give them out at the start. As 4 people from JR are getting medals you need to...

Yeh, I know that Ivan and Laurie are way, way above me. Your right that careless errors are not a trivial matter, when i first started olympiad I was losing 25-30% of my marks in careless errors. At first it didn't matter, I could still do very well, but eventually it got to the stage where it...

Graham White was definitely correct in saying that I am not in the running for the top place in 4U or even top 10. I currently maintain a rank about average for Ruse in 4U maths. I am putting all my effort into informatics, not HSC, because I can only do well in tests where the average is less...

who_loves_maths is correct, i did make to many mistakes. Even if we don't count the first, which i maintain is due to an ambiguity, my accuracy is still quite poor. The complaint about my excessive amount of errors was quite reasonable considering my unreasonable response to a request for a...

If it were to do about the HSC it would be boring. I went to a lecture last year, and we've already covered everything in it in class. The reason to go to the day is because the first two lectures may be interesting, assuming you choose a topic you know nothing about. The AM-GM lecture might...

I need to get the whole paper out because i only get 70-75% of the marks for questions i solve. How long do you have?

Ah, got it, a real geometric proof. Find the midpoints of the triangle. Draw a line through two of them to get a line parrallel to the base. Join both the bisection of this and the bisection of the base to get a line through the center. Bisect that.

Ok, I admit i'm lazy, i try to get people to fill it in for themselves so i don't have to type a lot. Ok, given any two lines you can find the intersection and any two point the line. Given a point and i gradient you know the equation of the line. Finally the gradient of a line perpencicular to...

Yeh i'm going. Can't remember what i'm going to, just not what i went to last year. The last set of lectures is all HSC based so it'll be very boring, probably skip out on that.

Sorry, i got my incircle confused with my circumcircle. I'm getting a bit rusty, i haven't done any serious maths (HSC maths doesn't count as serious) for almost a term. But this doesn't matter, the basic idea of the method (drawing lines on the the sides that will pass through the point)...
