SMO 2014


Changes in the structure of School Awards from 2014 onwards:

There is a major revamp of the structure of SMO school (team) awards from 2014. The School Awards will no longer be divided into Junior, Senior and Open sections. Instead, there will be two categories based on the age cut-off. Schools will be awarded points for the number of participants that registered and attempted the paper, as well as the number of Gold, Silver, Bronze awards and Honorable Mentions obtained by the students. The school will then be given an SMO School Award (Gold, Silver, Bronze and Participation) for each category based on the total number of points achieved. Please click here for details of the new School Awards system.

*Member schools must have paid the Year 2014 subscription fees in order to enjoy the concession rate. Membership application/renewal can be done together with SMO registration.

Registration Instructions


1.  Schools are responsible in ensuring that participants are within the age limits. A school will be disqualified if any of its participants are found to have breached the age limits rule, intentionally or otherwise.

2.  Only one registration form per school is needed for all competition categories.

3.  Only registrations completed on the provided template will be accepted. No other formats will be processed and the organizer will not make format conversions for schools.

4.  The column “Singaporean/PR” in the form must be completed. This is to facilitate IMO training selection.

5.      The completed form must be emailed as an attachment to smssmo@nus.edu.sg before 1 Apr 2014 . This deadline will not be extended due to tight working schedule.

6.     To add on participants after initial submission but before closing date, complete a second registration form and email as an attachment to smssmo@nus.edu.sg before 1 Apr 2014. Do not combine and submit with the initial list because it will slow down processing and may lead to errors. Late submissions will not be processed.

7.     To make amendments such as spelling after submission but before closing date, email the changes to smssmo@nus.edu.sg before 1 Apr 2014. Provide as much details as possible for quick processing. Late submissions will not be processed.

8.  Replacements/substitutions are not allowed once names are submitted. Registration fees will be forfeited for participants who could not or do not turn up for the competition.

9.  No further registration will be processed after closing date. Students who are keen to participate after the deadline may walk-in on the day of the competition and register on the spot. Cash payment must be made on the spot for registration to be effective.

10. Schools are responsible in ensuring that the submitted names are spelt correctly as these will be printed on the certificates. A charge of $5 per certificate will be levied for reprints.

11. Individuals (who are not registered by or representing any schools) are also welcome to register. Please follow the registration instructions listed above.

12. Foreign students who are residing overseas may participate in the competition. They are required to take part in the first round competition in Singapore. If they qualify for the second round, they are also required to do it in Singapore. Students from foreign schools will not be eligible for Individual or Team prizes. For registration details, please email to smssmo@nus.edu.sg.


13. Registration fee for students from local schools is $8.00 per person (from SMS institutional member schools) per competition category; and $10.00 per person (from non-institutional member schools) per competition category. If a participant enters more than one competition category, he/she will be charged accordingly. For instance, if a student from SMS institutional member schools participates in Junior and Open sections, he/she will be charged $8 x 2 = $16. Registration fee for students from overseas is $25.00 per person per competition category.

14.  Registration fees for students from local schools may be paid by cash, cheque or IFAAS. Payment must reach the organizer or be completed before 30 May 2014 . No extension is allowed. Registration will only be confirmed upon receiving the payment. For students from overseas, please email smssmo@nus.edu.sg to enquire about payment details.

20.  The organizer will no longer provide invigilators to schools.

21. Schools that intend to conduct the competitions within their premises have to arrange for their own teachers to invigilate the competitions (without monetary compensation from the organizer). Nevertheless, the organizer will continue to deliver/collect the question/answer scripts to/from schools. Details on such arrangements will be provided nearer the competition dates.

22. Schools conducting the competitions within their premises are still required to adhere to the same schedule of each competition category. This is to maintain fairness to all participants.


23. The organizer reserves the right to amend the rules and regulations of the competition.
