Q: What is IMDO? A: IMDO (International Medicine and Disease Olympiad) is an international online biomedical competition for secondary school students, covering human biology, anatomy, physiology, disease, and medical reasoning. Students in the USA qualify via USMDO. See imdolympiad.org for current rules and registration.
TL;DR The International Medicine and Disease Olympiad (IMDO) is an online biomedical competition. The organiser publishes the format and proctoring rules for each cycle on the official rules page. The IMDO rules also state that participants register through their country’s National Qualifier where available (for example, USMDO for the USA). Always check the current official notice for dates, fees, and exact format.
Status: IMDO rules + results pages checked 2026-01-26 - competition delivery, registration route, and proctoring can change by cycle; always verify on the official rules page before registering or paying fees.
Registration quick answer: Students should follow the official IMDO rules and check whether their country has a listed National Qualifier. If your country is not listed, use the organiser’s official pages to find the current registration guidance: https://www.imdolympiad.org/
1 What exactly is the IMDO?
The IMDO is a student biomedical competition run by its organiser, with the official rules published on the IMDO site.
Recent editions have been held online; refer to the current rules page for the latest delivery mode and schedule IMDO rules.
Participation figures and scoreboards are published by the organiser on the official site after each cycle.
1.1 Why parents of IP learners should care
Biomedical case-analysis forces students to convert prose into flow-charts, crunch proportional data and defend conclusions-skills that map directly onto IP WA graph questions and Paper 4 practical evaluation paragraphs.
2 Exam structure
The organiser publishes the section breakdown, timings, and proctoring rules in the current year’s regulations. Expect a mix of objective and free-response items focused on biomedical reasoning; consult the official rules page for the latest format and calculator/aid policy IMDO rules.
3 Pathway (country-based)
National qualifier - run by the country’s organiser (e.g., USMDO); dates, duration, and format are set locally.
Training - organiser-led preparation sessions where offered.
International round - held online per the current IMDO schedule; check the site for dates and delivery details.
The organiser posts official results and rankings on the IMDO site after each cycle. Refer to the “Results” tab for verified scores and participating teams IMDO results.
5 Transferable skills for IP Math & Physics

Mirrors which IP skill?
Resource to bridge
Drug-dosage dimensional analysis
Unit-conversion drills in Quantities & Measurement
Parents: If your IP child enjoys biology and already juggles Math/Physics WAs well, consider the IMDO as a low-cost, CV-visible challenge that sharpens graph-reading and dimensional-analysis. Students: Attempt one 30-question IMDO MCQ block this weekend and mark it using the 2024 key-you will instantly see which organ systems or statistics tricks need patching.
9 DSA and university admissions value
IMDO participation can be a useful addition to DSA portfolios and university applications, especially for students interested in medicine, biomedical sciences, or life-science programmes. The competition demonstrates biomedical reasoning and clinical data interpretation skills that go well beyond the standard IP or JC curriculum. For secondary school students, strong IMDO performance may support DSA applications to schools with established science or biomedical tracks. For JC students applying to medicine or biomedical science courses, IMDO results provide evidence of genuine interest and aptitude in the field. A strong foundation in IP Biology and IP Chemistry provides excellent preparation for the competition's content.
IMDO stands for the International Medicine and Disease Olympiad. It is an international online biomedical competition for secondary school students covering human biology, anatomy, physiology, disease mechanisms, pharmacology, and clinical reasoning. Full rules are at imdolympiad.org.
What does IMDO stand for?
IMDO stands for International Medicine and Disease Olympiad.
What is USMDO?
USMDO is the US Medicine and Disease Olympiad - the United States national qualifier for IMDO. Students in the USA (and sometimes other countries) compete through USMDO to qualify for the international round. See usmdo.org for current details.
Is USMDO legitimate?
Yes. USMDO is the listed US national qualifier on the IMDO official site and has published results from multiple competition cycles. As with any olympiad, verify registration details, fees, and schedules on the official pages before registering.
How do I register for IMDO 2026?
Check the IMDO rules page to see if your country has a listed National Qualifier.
If yes (e.g., USMDO for the USA), register through the national qualifier's site.
If no national qualifier exists for your country, check imdolympiad.org for open registration options.
Confirm current dates, fees, and proctoring requirements before registering.
Who is eligible for IMDO?
IMDO is open to secondary school students. Exact age and grade eligibility is published in the IMDO rules each cycle - check imdolympiad.org/rules before registering.
What is the IMDO exam format?
IMDO is held online with proctoring. It tests biomedical reasoning using a mix of objective and free-response questions. The exact section breakdown, question count, duration, and calculator policy are published in the official rules each cycle.
What topics does IMDO cover?
IMDO covers: human anatomy, physiology, pathology, disease mechanisms, pharmacology, medical statistics, and clinical data interpretation. A strong foundation in IP Biology and IP Chemistry provides excellent preparation.
Where can I find IMDO past papers?
IMDO practice materials are available at imdolympiad.org/resources and the USMDO site. The OpenStax Anatomy & Physiology textbook (free online) is a commonly recommended study resource.
Is IMDO useful for DSA or university applications?
IMDO participation can strengthen DSA portfolios, particularly for schools with science or biomedical tracks. For JC students applying to medicine or biomedical science programmes, IMDO results demonstrate genuine interest and aptitude in clinical reasoning. Verify your target institution's admissions criteria to confirm what competition evidence they consider.
When should I start preparing for IMDO?
Start 2–3 months before the qualifier by working through IMDO practice materials and building your anatomy, physiology, and clinical reasoning foundations. A strong background in IP Biology and IP Chemistry provides the core knowledge; supplement with OpenStax Anatomy & Physiology and clinical statistics resources.
