The Story Behind Twig Learning Center 


Twig Learning Center was founded by Mr Donnell Koh in 2008. Parents and students know him as the Deep Dive Chemistry expert who has helped over 3,000 junior college students achieve massive progress in H1/H2 Chemistry & clinch ‘A’s from ‘U’s in as little as 6 months.

As a teacher for the first batch of students from Meridian Junior College and a former Chemistry lecturer from Raffles Junior College, Mr Koh has worked closely with students from a wide spectrum of background and knows what works for students and what doesn’t.

Mr Donnell Koh started Twig Learning Center as he knows how it feels like to struggle with studying Chemistry. He was not a good Chemistry student in Junior College until he discovered the method to study effectively for the subject. His goal and purpose is to transfer this methodology and knowledge so they they can grow to love and do well in the subject.

"Teaching Chemistry is not my passion. It is my life. Chemistry is not difficult, far from the draining, boring subject that students may think it is.  If your child wants to experience Chemistry at a different level, improve immensely for the subject, Twig  is the place! I look forward to seeing your child at Twig!" - Mr Donnell Koh
