I believe this is what every parent dreams of for their ds/dd!
An digital learning system which combines score keeping with math olympiad qns to encourage children to practise more and keep track of their progress!

The setter of SMOPS paper told me HCI might be publishing a 20 year series.

This year's SMOPS is significantly harder than last year, the top score has dropped by almost 20 marks

Glad to see this interesting thread about maths Olympiad, I am a national team trainer and I have been to the IMO 4 times, twice as observer and Singapore IMO team trainer. I have started my maths Olympiad and maths tuition centre at Jurong east and quite a number of NMOS top 20 and SMOPS platinum and some SMO junior, senior and open top 30 attend my lessons now.
