Results for NMOS preliminary round should be out this week I think.....

Anyone knows what is the percentage of students that is invited to the special round compared to the whole cohort? If the child gets into special round, does that mean assured of a silver/gold?
Thanks.

Not directly related but might be useful for curious parents
2007 / 2008 / 2009
Gold 51 / 56 / 62
Silver 267 / 288 / 336
Bronze 460 / 476 / 538
Honourable Mention 830 / 616 / 1081
Participation 2235 / 2735 / 2902
Total 3843 / 4171 / 4919


Gold 1.33% / 1.34% / 1.26%
Silver 6.95% / 6.90% / 6.83%

If I am not wrong, getting into special round should guarantee at least a silver.

Thanks for the info. Very useful indeed!

Otherwise we will be clueless as DS still not getting notification from School.

Some schools do return the papers to the students. I have a student who took the test. After seeing him bugging me for the answers, I think there should be other students out there who might be curious to check their answers too. Hence I decided to post my \"unofficial\" ans :).

For the special round, are there any marks for steps if the final answer is wrong? thx.

If i m not wrong, its the same OAS format. 1st 10 qns worth 4 marks. nxt (and last) 10 qns worth 5 marks each.

Hi CoffeeCat,

Can you upload the 1st round NMOS paper so that my ds can recall his answers.
Thanks.

Based on your answers, my ds scored less than 50% although he got into the special round.
