Meet Mr Donnell Koh
Donnell began his teaching career as a pioneer teacher at Meridian Junior College before moving to Raffles Junior College, where he taught highly motivated students who expected to be intellectually stretched.
His teaching style is built around clarity, care, and strong foundations. Students learn Chemistry by understanding why concepts work, not by memorising blindly.
