IMO Questions and Answers
No. The IMO is a proof-based competition, and calculators are not permitted. You’re expected to derive results by reasoning and to present full written proofs. Preparation should focus on problem-solving strategies and clear mathematical writing, not computation tools.
Solutions are graded on a 0–7 scale per problem. Partial credit is common when you prove important lemmas, solve meaningful subcases, or make substantial progress toward the main claim. Clear structure and correct reasoning matter because graders must follow your argument.
Most IMO problems come from algebra, geometry, number theory, and combinatorics. Within those areas you’ll see techniques like inequalities, modular arithmetic, invariants, and classic geometry tools. The unifying skill is writing complete, rigorous proofs.
AMC and AIME are multiple-choice or short-answer contests that build speed and accuracy, while USAMO is proof-based. The IMO is international and typically harder on average, with six problems that demand deep creativity and polished proofs under strict time limits.
Countries submit proposed problems, and a problem selection committee shortlists and refines them. The final set is chosen with care to balance topics and difficulty across the six problems. Strict confidentiality is used to keep the contest fair worldwide.
It depends on your starting level, but many serious candidates train consistently over months or years. A practical approach is steady weekly work: focused topic study, several full proofs, and periodic timed sessions. Quality and reflection usually beat raw hours.
Common issues include jumping to conclusions without justification, skipping steps, and relying on pattern-matching instead of proving claims. Another mistake is writing unclear solutions that hide correct ideas. Practicing clean exposition and checking edge cases reduces these errors.
Feedback is crucial because small gaps can cost points. Work with a coach or math circle, compare your work to official solutions, and ask for detailed critique on clarity and rigor. Online communities can help, but prioritize high-quality reviewers and sources.
Use the last week to consolidate rather than learn new theory. Do a couple of timed mocks, review recurring mistakes, and practice writing clean solutions. Sleep, nutrition, and stress management matter—fresh focus often adds more points than last-minute cramming.
IMO week includes registration, an opening ceremony, two exam days, coordination and grading, excursions, and a closing ceremony with awards. Students often meet peers from many countries, while leaders handle translation and marking coordination with the jury process.
