How do people fail to answer even ONE question on a BMO1 paper?
BMO being british math olympiad. (something along the lines of this) http://www.bmoc.maths.org/home/bmo1-2005.pdf
I heard the modal score for people on BMO1 was failing to answer even ONE question? How is this even possible that people are so stupid? The first question to EVERY BMO1 paper is just trivial and a free correct mark pretty much. I had a look randomly at the other questions (Question 3 in the link above) and came to the answer of 21 in less than 10 minutes. Considering you have THREE AND A HALF hours to do the whole BMO1 paper, no one should really be failing to answer even ONE question; the result should be more at the other end, people averaging a failure to answer 1 BMO1 type question per paper, at most. You have THREE AND A HALF hours to do a few questions, and these questions aren't even that hard.
BMO1 questions are so easy, how is it that people are so stupid? My god.

It took you 10 minutes to do question 3? That is seriously slow, maybe you aren't as smart as you think.
that's my point. I'm a pretty stupid guy, but I'm finding it hard to believe that there are people even dumber than me. Statistics say that a large number of candidates fail to answer ANYTHING.
Edit: made an incorrect statement confirms my stupidity

something is not quite right with the statistics or possibly the interpretation ...

yep i just re-read what I wrote and realized how stupid i am. I wrote that without thinking.

Standard application of the proof of Schur's theorem. (The one from Ramsey theory.)
Original post by Smaug123
Can someone verify my solution to Q6? It was disconcertingly quick for someone with about three years more experience than normal BMO1 candidates.
Spoiler
Looks right, very similar to how I did it. Observing that puting x=1/2 gives you all the n/3 terms is a very strong hint at induction on the denominators. From there it is just a little algebra to work out which rations to use as x in the inductive step. Too easy for a final question I think.
People doing particularly badly on BMO1 is probably just a case of not knowing/understanding what's expected compared to say, the SMC, unless they've deliberately spent some time preparing for it.
Olympiad questions require proofs of statements as opposed to A-level 'plug and chug' style questions.
Maths challenge questions require a little bit more in the way of problem solving, but there's still no expectation that you come up with proofs.

Depends. You could get the numerical answer right to every question and still score <10 due to invalid assumptions or incorrect proof.

Is Q2 as easy as I think or have I made an incorrect assumption r faulty logic or something?
http://www.bmoc.maths.org/home/bmo2-2014.pdf
btw is the answer to Q1 http://www.bmoc.maths.org/home/bmo1-2005.pdf
1 and 5?

For Q2, how did you do it easily? I did it by showing that if there is a solution, then there is a solution for every numerical value the volume takes, then setting up a cubic polynomial with solutuions being exactly the side lengths and showing that it had a non-real solution (contradiction). I don't consider that an easy solution to find though.

Surely just solve for
l^3=12l
l^3=6l^2
12l=6l^2
Or am I really really bad at maths lol
show solutions are not equal

whats the answer to number 1?
1,2,3,5,7
I've just found 1 lol.
Off to create more eqns lol
