Alex Zhai, a 2008 graduate of Uni High, was one of six students chosen to represent the United States at this year's International Mathematical Olympiad. Zhai and his teammates were named to the U.S. team on Saturday, June 14, based on their scores on the USA Mathematical Olympiad exam and the Team Selection Test. The Harvard-bound Zhai won a silver medal at the 2006 IMO in Ljubljana, Slovenia, after his sophomore year and a gold medal at the 2007 IMO in Hanoi, Vietnam, after his junior year. The 2008 IMO will be held in Madrid, Spain, from July 10 to 22.
