    In what ways can you prepare for this test? I know that you can't revise for it like you can for A-level but stuff like prime numbers and shapes usually come up fairly often, am I right? What books or websites are useful for these kind of tests?

    Also, the scoring system is kind of strange, can someone provide any (mathematical) analysis on this? Also, does anyone know where you can find past papers and solutions to these? I only have the ones from the site with 'mathmo' username.

    Thank you.

    Its hard to prepare for the Maths Challenge. You can practice to get into the right frame of mind but it doesnt really help. I got past papers from my school teacher a few years ago but theyre at home (Im at Uni at the moment) so I cant post them for you. There are books but I dont know how good they are really.

    I have 'The Mathematical Olympiad Handbook' by Gardiner which is a useful book which I bought for when I did the BMO, but I wouldnt have thought it would be of much use for the Maths Challenge.

    As for the scoring, if I remember right the top 2.5% or so get a gold. It depends on the difficulty of the paper. If the paper is hard then the boundaries will be lower. However, I think the boundary for automatic entrace to the BMO Round 1 depends on how difficult they feel the BMO is going to be this year.

    Can anyone remember the boundaries for Gold and BMO for previous years? Obviously the values will change, but it would be useful nonetheless. Thanks.

    Haha, nice advice. Given enough time I can usually solve the more difficult ones, but not with a 1h30 time limit.

    The last time I did it you needed 81 for Gold, 92 (I think) for entrance for BMO. Although the year before it was something like 87 for gold, 89 for BMO.

    Wow, such a small difference between gold and BMO? It sounds quite encouraging from the 2001 paper I just did, but I have a tendency to fall to pieces when I actually go into the exam room. :rolleyes:

    Score = (Correct Answers * 4) - (Incorrect Answers * 1) + 25.
    Since it is multiple choice with 5 options, randomly guessing will leave you with 4 incorrect per correct. Therefore this system makes guessing an answer randomly have the same success rate as leaving an answer. The plus 25 is to stop anyone getting a negative score.

    Afraid not! I'm just looking at the past paper from last year: http://www.wpr3.co.uk/UKMT/smc.html

    Question 9 is quiet intriguing so far! :p:

    I think the answer for that one would be E 1005 but this is just an arrow in the dark. No idea, anyone care to shine some light on this?

    = 1/2005! (3)(4)(5)...(2005)(2006) = 2006/2 = 1003

    Ehh? Was that factorials? Didn't understand the (3)(4)(5), as a matter of fact, have you just eliminated all of the 1's and then taken just added it on to 2005 to get 2006/2 = 1003.

    Do you have a basic laymen's explanation Pwease.

    Multiply each bracket by the denominator of the fraction. The product of these numbers will be 2005! so you must multiply by 1/2005! outside the bracket. Then simplify.
