Mr Koh, former National Junior College (NJC) Further Mathematics lecturer, is very passionate about teaching Mathematics that he founded Modular Education Centre 20 years ago and has since been dedicating his time to nurture students in this subject. He is a highly sought-after tutor for his competence to simplify mathematics concepts clearly with “stunning ease and clarity”. His use of anecdotes to illustrate concepts and ideas is refreshing and it is simple wonder, then, that students’ attitude toward mathematics become more positive and they start to excel academically, from failing to passing and to scoring distinctions.

He customised lessons and worksheets to meet the needs of every student.  Being able to communicate effectively with students of different age group and various levels, he helped to build the confidence of many students who are struggling in the subject.  Parents, seeing great achievements in their older children often requested him to teach the younger ones.

I joined Modular Education when I was in Primary 6. Back then I didn’t like Mathematics. But after being tutored by Mr Koh, my grades improved and I slowly gained interest in it. Mr Koh could identify my weaknesses almost immediately, was able to guide me on ways to improve, and has a voice that attracts the attention of students. He also gave us many interesting ways to memorise certain fundamental formulas which made difficult topics much easier to handle. He showed us that many formulas which students were made to memorise can actually be derived from a few definitions. During lessons, the class is interactive and we are free to discuss different methods of solving questions with Mr Koh, as Mathematics is a subject that is free for people to understand in their own way. Mr Koh and Modular Education has made Mathematics much more fun and exciting for me, and has allowed me to foster friendships that last for life!

Hi Mr Koh, Thank you so much for your help and guidance in Mathematics. For the IB exams, I scored 44 points with 7 points in Math HL. I believe that your teaching and instruction has been very useful considering that I joined the class late in Year 6 and I scored mostly 5 for exams and common test. I hope that you will continue to teach and nurture the next few batches of IB students as you are an excellent teacher.

Student Testimonials

When I first joined Modular Education Centre, English was the course I signed up for taught by Mrs Manjit. During the weekly lessons, it made me realize how good of a teacher Mrs Manjit is. She will personally mark and check through the compositions and comprehensions and is very patient in clarifying any doubts whatsoever. Not only that, she guides students through the various tips and tricks needed for English. Her impeccable attitude towards teaching is in a way ‘motherly’ and she takes into consideration the weaknesses and strengths of each student and provides feedback to improve and hone one’s skills in their strengths. Even my results can vouch for her effectiveness as a teacher. From Term 2 to Term 3, my grades for English jumped dramatically from C5 in term 2 to A2 in term 3. All in all even though I have only been with the centre for 2 terms. Mrs Manjit as a whole is a very enjoyable teacher to be around and has impacted me greatly as a secondary student. Stephanas Lim (Sec 4)
