Preparing for the IMO exam? A printable IMO practice test PDF lets you review questions, test your knowledge offline, and build the exam readiness that timed, screen-based testing demands. Whether you are studying at home, commuting, or revisiting weak areas on paper, a printed practice test remains one of the most effective preparation formats available. This page provides a free PDF download and a structured study guide for the IMO examination. Practice with the free IMO - International Mathematics Olympiad practice test on PracticeTestGeeks (11 questions with answer explanations).
The IMO assessment tests candidates on the core competencies required for certification or qualification in the field. A strong preparation strategy combines repeated practice testing with targeted review of areas where accuracy falls below 70%. Use this PDF alongside the online IMO practice tests on this site for the most complete preparation experience — paper for review and annotation, online for timed simulation with instant scoring.
Candidates are tested across the primary knowledge domains that define competency in the IMO field. Each domain contributes a weighted percentage of the total scored questions. High-weight domains deserve proportionally more preparation time. The exam format is typically multiple-choice, and understanding the question structure — identifying the best answer rather than the first correct-sounding one — is as important as content knowledge.
Common high-priority areas include foundational theory, applied practice, regulations or standards governing the field, and scenario-based reasoning that tests judgment under realistic conditions. Review official exam content outlines from the certifying body to confirm current domain weights before your examination date, as content outlines are updated periodically.
Print the PDF, set a timer proportional to the number of questions, and complete each section without reference materials to simulate real exam conditions. After grading, categorize every incorrect answer by domain to build a targeted error log. Prioritize re-study in your weakest domains, then take an additional timed practice session to confirm improvement. Repeat the cycle until accuracy is consistently above 75% across all domains.

Before attempting practice tests, ensure you have reviewed the official study materials for the IMO exam. Most certifying bodies publish a candidate handbook or content outline that lists exactly what knowledge is tested. Read this document first — it tells you not only what to study but also what to ignore. Allocate study time in proportion to domain weights: spend more time on high-weight domains and less on domains you already know well.
Once you have reviewed the content, move to practice testing. Each practice test session should be treated as a diagnostic: the questions you answer incorrectly are more valuable than the ones you answer correctly. Keep an error log organized by domain. After three to four practice tests, patterns in your errors will become clear. These patterns tell you exactly where to concentrate additional study effort.
In the week before the IMO exam, focus on review rather than new learning. Take one full-length timed practice test to confirm readiness, then spend the remaining days reviewing your error log and reinforcing the concepts behind your most common mistakes. Avoid cramming new material in the final 48 hours — consolidation of existing knowledge is more valuable at that stage than attempting to add new content.
After completing this PDF, take full online IMO practice tests at IMO practice test — instant scoring with explanations for every answer. Use both formats together: this PDF for offline review and annotation, the online tests for timed simulation with immediate feedback. Together they give you the most complete IMO exam preparation available on a single platform.

Try these questions from our free IMO - International Mathematics Olympiad practice tests. The correct answer and an explanation follow each question.
How many 2-digit numbers can be formed using digits 1, 2, 3, 4 (without repetition)?
Answer: C. 12
There are 4 choices for the first digit and 3 for the second: 4 × 3 = 12.
For positive reals a, b, c with a + b + c = 3, what is the minimum value of a² + b² + c²?
Answer: B. 3
By the Cauchy-Schwarz or QM-AM inequality, a² + b² + c² ≥ (a+b+c)²/3 = 3, with equality when a = b = c = 1.
If a train covers 3/5 of a journey in 3 hours, how long will the full journey take?
Answer: B. 5 hours
If 3/5 takes 3 hours, the full journey = 3 ÷ (3/5) = 3 × 5/3 = 5 hours.
Divya plays squash every 3rd day and plays football every 4th day. She played both squash and football on 4th April. What is the next date when Divya will play both games?
Answer: A. 16th April
Explanation: Divya plays squash every 3rd day and football every 4th day. The next date when she plays both games will be the least common multiple (LCM) of 3 and 4, which is 12. Adding 12 days to April 4th, we get April 16th, when Divya will play both squash and football again.
