Alex Zhai, a 2008 graduate of Uni High, became one of six students chosen to represent the United States at this year's International Mathematical Olympiad. Zhai is aiming for his second gold medal in three tries.

The list of senior Alex Zhai's accomplishments seems to grow daily: newly selected member of the US. Physics Team, two-time Math Olympian, etc. Now you can add "movie star" to that list. Well, sort of. Alex is one of six students featured in a new documentary titled "Hard Problems," which chronicles the 2006 U.S. IMO Team as it prepared for and competed in the 47th International Mathematical Olympiad.
