Anne Arundel Community College has played sponsor to a countywide high school math competition since the early '70s.
This year a record eight competitors completed the fourth round, turning in perfect scores.
Individuals and teams compete in a one-hour test at the Arnold campus in which a score of 6 is perfect.
A school's total score is compiled by adding each school's top three individual scores to its highest team score.
Anthony Sawyer of Chesapeake High; Chris Kwak and Neal Motonaga, both of Meade High; Jason Farinelli of Northeast High; Geoffrey Atkinson and Adam Meyerson, both of Severna Park; and Jason Berger and Billy Chang of South River High, were the eight students turning over perfect scores.
