The Summit’s top-ranking Ohio female mathlete qualifies for USA Math Olympiad

Wanyi “Sherry” Xiao, a junior at The Summit Country Day School, took seventh place overall in Ohio during the April 1 state math competition in Columbus and, for the second year in a row, was the state’s top-scoring female student.

In a separate competition based on a national math test, Sherry qualified for the USA Math Olympiad (USAMO), ranking her among America’s top math students. Only 280 students qualified for USAMO this year. Among them, only two other students were from Ohio.   

After qualifying for the state test at a regional competition at Xavier University, Sherry competed in the Ohio High School Mathematics Invitational Olympiad at Capital University in Columbus on April 1. In the state competition, students are challenged individually and in ciphering (working with numbers) formats. In addition to finishing seventh overall, Sherry finished fifth overall on the individual test and fourth overall on the ciphering test. She received medals for her top finishes, a $20 prize and a Rubik’s Cube.

Top students who took the American Math Competition exam in October were invited to take the American Invitational Math Exam in March. This three-hour exam includes 15 challenging math questions. Sherry’s performance on both exams earned her the invitation to the USAMO.

During this school year as well, Sherry competed with other top high school math students from Ohio in November at the Harvard-MIT Mathematics Tournament (HMMT) at Harvard University. She also competed with a team of students from the U.S. and Canada at the Carnegie Mellon Informatics and Mathematics Competition in January. She attended a math competition camp last summer at Cornell University.

Sherry is an international student from China who lives with a host family. Since her freshman year, she has accelerated through The Summit’s math curriculum, taking above-grade level courses, and plans to take two college math courses during her senior year. A fitness enthusiast, this year Sherry has been on the cross country and indoor track teams and practices with the girls’ lacrosse team even though Ohio High School Athletic Association regulations prohibit her from competing. She is also involved with Leadership Scholars and is a member of next year’s Student Senate. She has been invited to serve as a youth counselor for juniors attending the Hugh O’Brian Youth Leadership Seminar at Urbana University in June.

“We have many international students enrolled in our school, and Sherry is an example of the richness they bring to our community of scholars,” said Head of School Rich Wilson. “While her accomplishments in math are outstanding, Sherry is actively involved in other aspects of our school community. I was thrilled to see our student body vote her on to the Student Senate. That was a recognition of the esteem they have of her and the inclusiveness of the Summit community.”
