USA - Kaylee Nguyen scored a perfect 108 on the AP math exam, placing her among only 16 people worldwide to achieve this score this year.
The East Side School District in San Jose, California, announced on October 3rd that two students from Silver Creek High School, Ritwin Narra and Kaylee Nguyen, achieved perfect scores in Calculus on this year's AP (Advanced Placement) exam. A representative from the school district stated that Kaylee Nguyen is of Vietnamese descent and is currently attending the University of California, San Diego.
AP (Advanced Placement) is an advanced placement program (also known as college preparatory), very popular in American high schools. The program is optional and includes 38 elective courses, helping students familiarize themselves with the fundamental knowledge required at the college level and increasing their competitiveness when applying to university.
The exam, organized by the College Board – the organization that owns the test – was held in May. Out of approximately 136,000 students worldwide who took the three-hour, one-fifth-minute math exam, 16 achieved a perfect score of 108/108. The subject tests candidates' knowledge of derivatives, integrals, and their applications in motion, volume calculation, tangents, and broader topics such as polar coordinates, differential equations, and infinite series.
The exam score is calculated based on two parts: multiple-choice and essay, then converted to a scale from 1 to 5. Students scoring 70-108 receive 5 points; 59-69 is equivalent to 4 points. The remaining scores (0-27, 28-44, and 45-58) correspond to 1-3 points.
Typically, students who score 3 points or higher are exempt from equivalent courses at many universities in the US and around the world.

Leena Guttal, Kaylee Nguyen's teacher at Silver Creek High School, has been teaching advanced math for 28 years and once had a student achieve a perfect score on the AP exam in 2014. The teacher stated that the probability of achieving a perfect score on this exam is extremely low.
"Both Ritwin Narra and Kaylee Nguyen are intelligent, independent, proactive, and highly capable," Ms. Guttal shared. Speaking specifically about the Vietnamese-American student, she described Kaylee as "meticulous, thorough, and very hardworking."
"All the credit really goes to Ms. Guttal. She put so much effort into teaching us calculus and organizing the mock exams. I've never had a teacher like her," said Kaylee Nguyen, adding that her teacher helped her understand calculus better, instead of just memorizing the steps to solve a problem.
