MISHAWAKA, Ind. — An Indiana high school student accomplished a feat no one else in the world could do this spring. Felix Zhang, a junior at Penn High School in Mishawaka, was the only student in the world to get every question on the AP Calculus AB exam correct.  That's 108 out of 108 questions right! About 270,000 students took the exam worldwide, according to the Penn-Harris-Madison School Corporation. While 20% of the students received a perfect "5" rating on the test, Zhang's was the only perfect score.
