College Board administers worldwide AP calc exams every year. The point system ranges from one to five, with a three or higher considered a passing score.
While more than half of her class scored a five on the AP calc “AB” exam, one student achieved the unprecedented.
“It was really nice being able to have a perfect score. It was pretty surprising,” said Felix Zhang, a Penn High School junior.
Zhang is the only student in the entire world — ever — to earn a perfect score.
He didn’t miss a single point.
“I wanted to do well on it, and I prepared a lot, but I never actually thought about getting a perfect score before,” Zhang said.
