OUR STORY

From a dad who wanted his kids to score 9

“My family doesn’t speak English at home. My son only studied ‘200 ISEE words’ — then got shocked by the real test.”

Starting May 2023, Prof. Yangming Ou (Harvard Medical School) and his sons collected unknown words from books, radio, and mock exams. Using big data (5 million books, 370k words), they built a 3,000‑word corpus — after 17 versions. The result? Scores jumped from 4 to 6, 7, 8, and finally 9 (99th percentile) in the ISEE middle level.

— Prof. Yangming Ou, PhD

Associate Professor, Harvard Medical School & Boston Children's Hospital
