HONOLULU (HawaiiNewsNow) - Talk about math whiz kids!
All 57 seniors in a Punahou School calculus class have learned they scored a perfect 5 on their AP Calculus exams.
The students were in an AP Calculus BC class -- that's the second of two calculus classes that Punahou offers.
"Nationally, this happens very rarely," said Janet Chang Oshiro, a Punahou math teacher.
Students take AP classes in order to earn college credit. Typically, to get that credit, students had to score a "4" or "5" on the exam.
