Hello, I'm Harrison He.
My name is Harrison He. I'm a Cambridge Honours graduate from St John's College with outstanding A-Level results, including A* grades in Mathematics and Further Mathematics.
I'm heading to the University of Illinois Urbana-Champaign to pursue a Bachelor's degree in Mathematics, with the potential to pivot into Computer Science + Mathematics. Beyond academics, I'm passionate about actuarial science, having job-shadowed at two leading firms, and I've dedicated over 100 hours to tutoring high school maths and Olympiad students.
