A 17-year-old student at Abraham Lincoln High School in Los Angeles got a perfect score on the AP calculus exam.
Cedric Argueta is one of only 12 students around the world to earn the perfect score, according to a statement from the Los Angeles Unified School District.
More than 300,000 students took the exam last year.
Argueta spent countless hours preparing with teacher Anthony Yom.
As soon as I got some of his work, I saw what a bright kid he was.
