Just One Teen on the Planet Aced This Test

On planet Earth, some 270,000 students took the AP Calculus AB exam in May 2022. About 20% of them scored a 5, which is the highest score possible. But Felix Zhang did something no one else did: The Indiana high schooler got a perfect score. Then a sophomore at Penn High School in Mishawaka, Felix emerged with 108 points out of a possible 108 on the multiple-choice test. WNDU reports Felix said he ended up fortuitously changing one answer while double-checking his work.

Fox News notes that 2022 saw the highest percentage of students score a 5 since 2016. Still, Felix didn't expect to stand alone in his feat: "I felt pretty confident knowing that I knew what to do on the test, but there was always a chance I would make a small error ... I'm pretty surprised that no one else got a perfect score." WVPE notes Felix is taking calculus BC this year, and WNDU adds he isn't alone in his math prowess in his family: His parents both teach math, his mom at Indiana University South Bend and his dad at Notre Dame.
