TL;DR
The International Mathematical Olympiad is a two-day, six-problem battle of ingenuity. Roughly half of all contestants earn medals, and Singapore's systematic SMO-to-IMO pathway means IP students who love proofs can convert enrichment hours into international podiums and scholarship advantages.

1 Why parents of IP students should care

Curriculum stretch: IMO problems on number theory, combinatorics and geometry extend far beyond the H2 syllabus and overlap with H3/Further Math content.
Scholarship signalling: Agencies such as DSTA and universities often cite Olympiad medals as an advantage at interview.
Transferable habits: Proof-writing, pattern spotting and time-boxed problem solving lift WA grades once re-applied to vectors, calculus and even physics derivations.

2 A 60-second history

Year	Milestone
1959	First IMO held in Romania with 7 Eastern European teams.
1967	Western countries join; UK debuts.
1977	First non-European host (Yugoslavia invited 3 non-European teams).
1980	Only gap year in IMO history — postponed logistical year.
2023	Indonesia hosts 112 countries; global female participation tops 10 %.

3 Who may take part

Contestants must be under 20 on 1 July of the competition year and not enrolled in tertiary education.
Each national delegation may bring up to six students, one leader and one deputy leader.
Team leaders sit on the Jury that finalises problem statements and mark schemes.

4 Contest format

Day	Duration	Problems	Points
Day 1	4 h 30 min	Problems 1-3	\(3 \times 7 = 21\)
Day 2	4 h 30 min	Problems 4-6	\(3 \times 7 = 21\)

Each script is double-marked; disagreements go to a coordination panel. The maximum individual score is \(42\).

5 Medals and honourable mentions

Gold : Silver : Bronze = 1 : 2 : 3 by headcount, targeting roughly the top 50 % of contestants.
A perfect solution to at least one problem but no medal earns an Honourable Mention.
Team awards are the sum of individual scores; ties are not broken.

6 Growth and participation trends

From 7 teams in 1959 the IMO now welcomes more than 100 countries each year.
Female participation hovers near 10 %, sparking spin-offs such as the European Girls' Mathematical Olympiad (EGMO) founded in 2012.
Hosting rotates worldwide; recent editions include Bath (2019), Chiba (2020-online), Oslo (2022) and Chiba again (2023).

7 Singapore pipeline: SMO → NTST → NTTP → IMO

Singapore Mathematical Olympiad (SMO): Junior, Senior and Open sections run by the Singapore Mathematical Society.
National Team Selection Tests (NTST): Top Open scorers sit two proof-based papers to shortlist ~15 candidates.
National Team Training Programme (NTTP): Weekly problem-solving and residential camps refine techniques.
Final six: Confirmed in May, the team attends the IMO with leader and deputy leader.

Singapore first competed in 1988 and has frequently secured at least one gold medal in recent editions, including double golds in 2022 and 2023.

8 How IMO-style training benefits IP WA performance

IMO skill	Direct IP payoff
Modular arithmetic tricks	Streamlines remainder proofs in H2 vectors and induction questions.
Extreme principle & bounding	Sharpen inequality handling in A-Math and H2 calculus optimisation.
Synthetic geometry	Boosts speed on circle-theorem sections of SMO and school trig quizzes.
Four-colour diagram proofs	Strengthens explanation marks in physics free-body diagrams.

9 Integrating IMO prep with the IP academic calendar

Term window	School load	Recommended action
Nov-Dec	Post-exam holiday	Join a 10-session Olympiad fundamentals camp (number theory + combinatorics).
Jan-Mar	Light WA load	Drill SMO past papers under 1.5 h timer.
Apr-May	NTST window	Swap weekly tuition slot for 4 h proof-writing workshop.
Jun	National team camp	Practise 4 h 30 min mock days, recover with daily mobility and 8 h sleep.
Jul	IMO itself	Keep WA revision ticking with 30 min spaced recall sessions.
