Senior Alex Zhai scored 14 out of a possible 15 on the American Invitational Mathematics Examination II earlier this month, giving him a near-perfect selection index of 290 for the U.S.A. Math Olympiad. Zhai will take the USAMO exam on April 29 and 30. The USAMO is the next-to-last step in the process that determines who will be on the six-member U.S. team in the International Math Olympiad. Zhai has represented the U.S. for the past two years, winning a gold medal last summer in Hanoi, Vietnam, and finishing seventh individually in the world.

Once again, Alex Zhai has earned a perfect score of 150 on the American Mathematics Contest 12 national exam. The senior is one of six Uni students who have qualified for the American Invitational Math Exam, which will be given on April 2. The others are Geoffrey Beck, Ethan Berl, Allan Luo, Mike Renner, and Brian Wang.
