The National Science and Maths Quiz (NSMQ) started in 1993 as the Brilliant Maths and Science Quiz for senior high schools (SHS).
Since then, the NSMQ has evolved over the 25 years, mentoring the nation’s great talents that will move the country to a different level.
With the exception of 2010 and 2011 when the quiz was not held, this year’s edition will make the 23rd edition of the contest.
