My DS also sat the challenge instead of history lesson, was an hour long. Top 1000 get a certificate I think..
According to the website (please see the quote below), top 40% of students get some kind of certificate. I read some where else that about 80,000 to 90,000 students appear for this. Top 1200 get to participate in the Maths Olympiad - which is a very high achievement I reckon.
DD is in Year 6, and therefore it is only for fun
. Btw, the website now has both the question paper, and solution set. So, you can get your DCs to check how many they got right
