A: Everything IP parents and STEM-inclined students need to know about the IChO - from the 5-hour lab exam format and medal cut-offs to how national selections.
TL;DR
The International Chemistry Olympiad (IChO) is the world's premier high-school chemistry contest. Each of the participating nations sends four students and two mentors to sit a 5-hour laboratory practical and a 5-hour written theory paper on separate days. Medals are awarded to the top half of the field with cut-offs fixed by the jury after marking. For Singapore IP learners, qualifying begins with the Singapore National Chemistry Olympiad (SNCO); similar pipelines exist worldwide (e.g. USNCO in the USA). The advanced stoichiometry, kinetics and spectroscopy problems reinforce calculus, data-handling and graph-interpretation skills that also boost IP Mathematics and Physics grades.
Map every derivation back to the JC syllabus with our H2 Chemistry notes hub so Olympiad drills double as 9729 revision.
Registration quick answer (Singapore): Students don’t enter IChO directly. Countries send national teams via their chemistry olympiad. See the IChO site for rules and hosts: http://icho-official.org/
1 What exactly is the IChO?
The IChO is an annual international science olympiad founded in 1968 and now attracts delegations from roughly 90 countries each July. The event is governed by statutes agreed upon by the International Jury, published by the IChO International Information Centre in Bratislava.
