Los Alamitos High School is saluting student Christopher Yeh, who earned a perfect score on his Advanced Placement exam in spring 2012.
Yeh did something more amazing than just getting a top score of 5, which ranks him "among 15.5 percent of students who did so in 2012,"
He was one of "only 17 students in the world" to earn all 108 points possible on the Calculus BC Exam, which has multiple-choice and essay questions, according a statement from the Los Alamitos Unified School District.
More than 94,000 students took an AP Calculus BC Exam in 2012.
"Everyone here at Los Al couldn't be more proud and excited for Chris and this tremendous accomplishment," said Principal Joshua Arnold in an LAUSD press release.
Arnold says that Yeh's accomplishments go beyond the classroom. He's a tutor, a campus leader and a "tremendous humanitarian doing excellent work for the students and families of Los Alamitos High School."
