The International Mathematical Olympiad, or IMO, is an annual mathematics contest in which 7 of the finest mathletes from each country participate in. (Not all 195 countries in the world may participate.) The IMO is part of a long “chain” of contests. For students in middle school, the AMC 8 (a 25-question multiple choice test) is the first test, then the AMC 10 (which is similar to the AMC 8 except for the scoring), then the AIME (a 15-question test in which all answer choices range from 0-999 inclusive), the USAMO (a 6-question proving exam with two days, three questions per day), and finally the IMO (similar to the USAMO). For students in high school, the AMC 10 is the first test, then the AMC 12. The rest is similar to what middle-schoolers experience.
Well, finally the overly verbose and abstruse avid reader is done with his blabbering about. Here is the website for the results: http://www.imo-official.org/results.aspx, or in order, http://www.imo-official.org/year_country_r.aspx?year=2009. If you’re too lazy to click that link and view the results, here are the notables (what I call “main events”):
- The People’s Republic of China finished 1st.
- Japan finished 2nd.
- The Russian Federation finished 3rd.
- United States finished 6th.
- North Korea beat the United States.
- One of China’s mathletes got perfect score.
- All six members from China got at least 5 questions with perfect score.
- All six members from China got gold medals.
- The leading mathlete of United States, John Berman, from North Carolina, got 5 questions with perfect score.
