The Founder, Mr. Donnell Koh

Mr Donnell Koh of Twig Learning Center has experience teaching the A-Level Syllabus and understands how to get you focus on key concepts and most importantly apply them with ease. He graduated from NUS Chemical Engineering with 2nd Upper Honours. He used to work as Chemical Engineer however deep inside he always wanted to be a teacher, so after 3 years of working in the private sector, he enrolled into National Institute of Education (NIE) to get his Post Graduate Diploma in Education (PGDE).

Since my first lesson, I have found Mr Koh's lessons to be very helpful and informative. His notes are clear cut, without any unnecessary information, which really speed up my learning process. Coupled with you continuously going through with us questions to develop that much needed rigour for chemistry, I was able to improve tremendously. Mr Koh was also patient with my questions and would not hesitate to spend extra time out of lesson to answer my queries. I managed to get an A for chem!

CHEE YIT 2015 - 2016

I am very thankful to have had Mr Koh tutor me A-Level Chemistry for the past 2 years. His interpretive notes and experience in teaching really allowed me to understand the concepts of each topic a lot better. Whenever I had doubts, Mr Koh was more than willing to take the time after class to give me additional coaching. In addition, when examinations were nearing, he even opened up slots during the study break for us to consult him individually. He also provides many practices, equipping students with the right skills for examinations. His dedication and patience allowed me to improve drastically, scoring an A for H2 Chemistry. I would definitely recommend him to my juniors! Thank you Mr Koh!!
