How to Crack IMO 2025-26: Complete Preparation Guide for Classes 1–12

What is the IMO?

The International Mathematics Olympiad, conducted by the Science Olympiad Foundation (SOF), is India's largest school mathematics competition. More than a million students across Classes 1–12 appear each year. A strong IMO performance earns school-level, zonal, and national medals — and the highest scorers qualify for Level 2.

Exam pattern

The IMO has two levels:

Level 1 — conducted at your school. Multiple-choice questions (MCQ), no negative marking in most classes.
Level 2 — for top performers from Level 1. Harder questions, same MCQ format.

Section breakdown by grade group:

| Section | Grades 1–4 | Grades 5–12 | |---|---|---| | Logical Reasoning | 10 Qs | 15 Qs | | Mathematical Reasoning | 10 Qs | 20 Qs | | Everyday Mathematics | 10 Qs | 10 Qs | | Achievers Section | 5 Qs | 5 Qs | | Total | 35 Qs | 50 Qs |

Duration is 60 minutes. The Achievers Section carries higher marks per question — don't skip it.

Syllabus overview

The IMO follows the NCERT curriculum for your grade, with olympiad-style questions that go one or two levels deeper. Key topics:

Number systems — factors, multiples, LCM/HCF, integers
Algebra — linear equations, expressions, polynomials (Grade 8+)
Geometry — triangles, circles, quadrilaterals, coordinate geometry
Mensuration — area, volume, surface area
Statistics & probability — mean, median, mode, basic probability
Logical reasoning — series, patterns, analogies, classification

8-week preparation plan

Weeks 1–2: Baseline

Take one full-length mock test under real conditions — 60 minutes, no pausing. Score yourself honestly. Identify which sections cost you the most marks. This is your baseline.

Weeks 3–5: Concept work

Work through your weak topics using your textbook. For each concept, solve at least 10 olympiad-style problems — not just textbook exercises. SOF-pattern problems have a different texture: they test application more than recall.

Week 6: Mock tests

Take 2–3 full-length timed mocks per week. After each, spend as long on the review as you did on the test. Read the explanation for every question you got wrong.

Week 7: Achievers Section focus

The Achievers Section is where ranks separate. It tests higher-order thinking — problems that require multiple steps or creative approaches. Dedicate specific practice sessions to this section.

Week 8: Light revision

Reduce volume. Review your error log from the past 7 weeks. Take one final mock 3 days before the exam. Rest the day before.

Common mistakes to avoid

Skipping Logical Reasoning. Many students treat LR as a bonus section. It's not — 15 questions in Grades 5–12 at the same marks per question as the main sections. A student who masters LR gains an outsized edge.

Doing practice in open-book mode. Always work under timed conditions, even for individual problem sets. Olympiad problems require fast mental computation — that skill only comes from pressure practice.

Ignoring previous years' patterns. SOF recycles question styles even when it changes values. Studying 3 years of papers gives you a strong intuition for what to expect.

Confusing olympiad preparation with board exam revision. Board papers test coverage; IMO papers test depth. A student who has solved 500 olympiad problems in their weak areas will outperform a student who has revised their entire textbook.

How to use SuperWicket for IMO prep

Every test on SuperWicket is timed by our server — same pressure as the real exam. After each submission:

Check the section-by-section breakdown of your score
Review every question you got wrong — read the explanation before moving on
Note the type of mistake (concept gap, calculation error, time pressure, misread)
Filter your next practice session to that question type

Consistent 3-week improvement in your SuperWicket score almost always predicts real IMO improvement. The platform shows your rank against other students on the same test — use that as a calibration, not a source of anxiety.
