On March 14, the 2015 Southern California MATHCOUNTS competition was held at University of California Irvine. The annual math competition for middle schools involved over 200 students.

A standard Mathcounts competition consists of four rounds: the Sprint Round, the Target Round, the Team Round, and the Countdown Round. The Sprint round is a written exam of 30 problems, the Target Round contains eight mini examination problems, the Team Round is a 10 question exam, and the Countdown Round has contestants go head to head in answering math problems.

Ardent student Anton Ni, who attends Jeffrey Trail Middle School, placed second in the individual competition and first in the countdown. In the Countdown Round, students must answer math questions read by a proctor as quickly as they can in front of a live audience.

Jeffrey Trail Middle School finished third in team competitions. .
