USA - Kaylee Nguyen scored a full 108 on the AP Math exam, one of only 16 people in the world to achieve this score this year.
The East Side School District in San Jose, California, USA, reported on October 3 that two students from Silver Creek High School, Ritwin Narra and Kaylee Nguyen, achieved perfect scores in the calculus subject on this year’s Advanced Placement (AP) exam. A school district representative said that Kaylee Nguyen is Vietnamese and is currently studying at the University of California, San Diego.
AP is an advanced placement program (also known as college preparatory), very popular in American high schools. The program is not compulsory, includes 38 subjects for students to choose from, helps them get acquainted with basic knowledge at the university level and increases their competitiveness when applying to this level of study.
The exam was administered by the College Board, which owns the test, in May. Of the approximately 136,000 students worldwide who took the three-hour, 15-minute math test, 16 people earned a perfect score of 108/108. This subject tests candidates’ knowledge of derivatives, integrals, and applications in motion, volume, tangents, and extended topics such as polar coordinates, derivative equations, and infinite series.
The test score is calculated based on two parts: multiple choice and essay, then converted on a scale of 1 to 5. Students who score 70-108 are given 5 points; 59-69 is equivalent to 4 points. The remaining levels are 0-27, 28-44 and 45-58, corresponding to 1-3 points.
Typically, candidates who score 3 or higher are exempted from equivalent courses at many universities in the US and around the world.

Leena Guttal, Kaylee Nguyen’s teacher at Silver Creek, has taught Advanced Placement Math for 28 years and had a student who scored a perfect score on the AP exam in 2014. The teacher said the odds of getting a perfect score on the exam were extremely low.
"Both Ritwin Narra and Kaylee Nguyen are intelligent, self-motivated, energetic and very capable," Ms. Guttal shared. Speaking specifically about the Vietnamese-American student, she commented that Kaylee is "meticulous, thorough and very hard-working."
"All the credit really goes to Ms. Guttal. She worked so hard to teach us calculus and give us mock exams. I've never had a teacher like her," said Kaylee Nguyen, adding that the teacher helped her understand calculus better, rather than just memorizing the steps to solve a problem.
