Upper Schooler Earns Perfect Score

Ryan Kulsakdinum ’23 earned a perfect score of five on the May 2021 AP Computer Science Principles Exam, becoming one of only 335 students (amounting to just 0.29% of 2021 AP Computer Science Principles Exam takers) from around the world to earn every point possible on this challenging, college-level examination.

“Ryan’s strength lies in his ability in precision-thinking, and strong logical skills in analyzing and unravelling complex algorithms,” said AP Computer Science Teacher Poonam Gupta. 

“With very little fanfare, he will steadily work through a problem, using a variety of conceptual strategies until he almost invariably arrives at the solution. Being such a creative independent thinker has clearly made Ryan an excellent problem-solver.

“It is these qualities that helped him produce a flawless result on the AP Computer Science Principles exam!”
