Summit Country Day School junior Junbo “Tom” Li, Mason, who previously dominated Ohio students on the American Math Competition (AMC) 12 exam, ranked among the top 2.9 percent out of 2,773 multi-national participants on the American Invitational Mathematics Examination (AIME) in March.
He scored 12 out of 15 on the demanding three-hour test.
Tom had qualified for the AIME after achieving the top mark in the state on the AMC12 exam and placing in the top 5 percent nationally. Tom’s score of 144 on that earlier test, which covers trigonometry, advanced algebra and advanced geometry, was the highest in the last nine years among Ohio students, according to Summit Upper School math teacher Eric Unwin.
The 15-question, three-hour test has been given since 1983 to students throughout the country, U.S. affiliated nations like Guam and Puerto Rico and schools around the world that are AMC international partners.
