IMO Hong Kong Preliminary Selection Contest

Each year, the IMOHKC organises a preliminary selection contest in May or June. The contest normally lasts for 3 hours and contestants have to solve about 20 problems which require answers only. High-achievers of the contest are then invited to take part in a year-long training programme which selects the Hong Kong team to IMO.

IMO Team Selection Tests

During the year-long training programme, several tests are administered and the results from these tests will be used to select the Hong Kong team to IMO. These include the CHKMO in November or December, as well as the APMO in March.

Past papers and solutions of the CHKMO will be added soon.
