Indiana student only one in the world to win perfect score on Calculus exam

By James On Sep 26, 2022

An Indiana high school student has become the only student in the world to achieve a perfect score on the Advanced Placement Calculus AB exam, with 108 of 108 questions correct.

Felix Zhang, who attends Penn High School in Mishawaka, Indiana, scored every possible mark on the AP Calculus AB exam.

He was one of 270,000 students worldwide to take the AP exam in May 2022, while still only a sophomore. He is now a junior student.

Zhang’s AP Calculus AB teacher at Penn High School last school year was Ms. Denise White, who this year is teaching Zhang again in the next grade of AP Calculus CB.

Ms. White has been a teacher for 30 years and is in her fourth year teaching AP Calculus at Penn.

About 20% of students who took the test achieved a score of five in May, the highest mark and percentage since 2016.

“It was quite surprising because like doing the test, I wasn’t really expecting anything and of course I wanted to do it right, and I prepared well, but I never thought about getting a perfect score before, so that was a nice surprise,” said Felix WNDU.

Both of his parents are college-level math teachers, he said.

His mother works at Indiana University South Bend and his father at Notre Dame.

Felix said: “I felt pretty confident knowing I knew what to do during the test, but there was always a chance I would make a small mistake or something,” he told reporters.

“So I wasn’t really expecting to see a perfect score.

“And that was quite surprising to me, because I had the feeling that there are a lot of other people who probably do very well on this test, and I’m quite surprised that no one else got a perfect score.”

AP exams help students earn college admissions, scholarships, and other financial aid.

Colleges and universities around the world receive AP higher education scores.

His teacher Mrs. White said, ‘I love the students. I think that’s why I do it. I call them my children because now I have a daughter who just graduated and she is in college. And so they kind of filled that gap for me.

“I like going to their sporting events. I sponsor two clubs; and I coached here at Penn. So just being involved in the students’ lives is a lot of fun for me.

“It’s not a profession you can probably do without loving it. I don’t know what I would do if I didn’t teach.”

Teachers can apply many strategies to help students learn, Penn Principal Sean Galiher said in a press release.

He added: “But when you have kids who score out of a five, you know the curriculum is intentional, it’s focused, the kids are engaged and there’s a collaborative environment.

‘If you take an AP Calculus course in secondary school, you are actually doing Calculus as a student for the first year; and that’s the whole reason we’re promoting double-credit and AP-type courses here at Penn High School,” he continued.

‘We want students to feel prepared so that they can graduate from university and complete their studies in at least four years.

“So if we can expose them at the high school level and help them experience the rigor and the challenge and be successful, we know they will be successful when they leave our walls.”

“This outstanding achievement is likely a direct reflection of the quality education offered at Penn High School,” Trevor Packer, head of the Advanced Placement Program, said in an email to the principal. Fox news.

“We applaud the hard work of Felix and the AP teacher responsible for engaging students and enabling them to excel in a college-level course.”

Penn has approximately 3,500 students and ranks in the top 3.67% of Indiana’s public school districts, according to the press release.

Zhang attended Northpoint Elementary and Discovery Middle School. His parents could not be reached for comment before MailOnline went to press.
