International Medicine and Disease Olympiad
The International Medicine and Disease Olympiad (IMDO) is the World Championship Medical and Disease knowledge/problem solving competition for High School students and is held annually online in July/August. The first IMDO was held in 2015 in San Diego, CA, and subsequently was moved online to lower the cost to compete for students throughout the world. The IMDO Foundation Board ensures that the competition is held each year and that each country selects their team in a fair and transparent process.
The IMDO aims to promote interest in the medical field by recognizing the strongest high school problem solvers interested in medicine. The IMDO aims to test both basic medical knowledge related to human medicine and disease, as well as problem solving abilities related to figuring out the best courses of actions given clues that a medical professional might encounter in their career.
The International Medicine and Disease Olympiad is held each year at the end of July or beginning of August. In 2022, the IMDO is scheduled for July 30, 2022. The competition will be held online, and consist of a mix of multiple choice questions and free response questions. The exam will be 3 hours in length, and test both knowledge and problem solving skills related to medicine and disease. The exam can be taken at any time on July 30, 2022 between 9:00-23:59 Pacific Time.
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:
