Selection Process

The K3M is a national level test offered to most secondary schools. Every year, top scorers of the selection test will be invited to join the IChO training camp.

Starting from 2021, Universiti Malaya has also started the Go For Gold (GFG) training programme as one of the steps to achieving a Malaysian gold medal in the IChO. As for now, invitations to the programme are sent directly to school administrators and not open to the public.

Within the training camp, several tests will be held and the top 4 scorers will be chosen to represent Malaysia in the IChO.


International Chemistry Olympiad (IChO) is an annual olympiad for high school students who excel in chemistry and is the third oldest ISO to date. Established in Czechoslovakia 1968, up to 80 countries send teams of 4 members to compete in the olympiad, helping encourage cooperation between students from different countries at an international level.

Problems within IChO touch upon several subjects within chemistry, mainly divided into Physical Chemistry, Organic Chemistry and Inorganic Chemistry and students’ knowledge is tested at an extremely high level.


There are 2 rounds.

  • Theoretical Round
  • Experimental Round

Do note that due to the recent pandemic, IChO 2020, 2021 and 2022 were organised without a laboratory exam. 


Contestants must be younger than 20 years old, and are not enrolled in any tertiary education institutes at the day of competition.
