The IMDO is level set at around 1st year medical school knowledge of human disease and medicine. The knowledge being tested will likely be something you would be expected to know after a first year in a US-based medical school. There may be questions that push these boundaries a little (ie. more global in scope), but these will be the minority of questions. The following are some resources that we encourage students interested in the IMDO to explore and study:

  • Foundational Texts (foundational resources tested at every round of the competition, even at the national level):

    • Campbell Biology (11th Edition) by Lisa A. Urry, Michael L. Cain and Steven A. Wasserman

  • Applied Texts (High yield resources tested more heavily in the international level):

    • First Aid for the USMLE Step 1 2022 (32nd Edition) by Tao Le and Vikas Bhushan

    • Fundamentals of Pathology by Husain A Sattar

  • Advanced Texts (Not necessary to answer competition questions even at the international level):

    • Harrison's Internal Medicine

    • Robbins' Pathologic Basis of Disease

    • DeVirgilio's Surgery

  • Honorable Mentions:

    • Lippincott's Illustrated Reviews series (great for visual learners out there)

    • Anki Decks

    • Online Amboss Library
