Looking for the Best Chemistry Tuition Centre?

Are you struggling with Chemistry? Chemistry is a challenging subject and it is not easy to master. It is integrated with mathematics, physics and biology and the content can be overwhelming. It has lot of abstract theories which are not easy to grasp,

Over the years, the syllabus has changed drastically. You look at a question and you don’t know where to start. You keep reading your notes to find the answers and yet you are still lost.

If you can relate to this, you have come to the right place.

Our tutor for Chemistry, Mr Donnell Koh, was a former Raffles Institution (JC) and Meridian Junior College teacher with a wealth of experience teaching the A level syllabus and a superb track record of getting students to excel for the A-level Chemistry exam (90% As and Bs).

Twig Learning Centre started off specialising in A-level Chemistry. Over the years, the centre has seen many students graduating at the top of their A-levels cohort. Because of the many requests, we plan to start O Level Chemistry tuition and IP Chemistry tuition on top of A Level H2 Chemistry tuition classes.

Why join Twig Learning Centre?

Whether you are looking for  secondary 3 chemistry tuition or secondary 4 chemistry tuition, you have come to the right place. To learn more, please see below.


Twig Learning Center notes are so clear and concise that we believe they are probably better than those from many top schools. Many of our students told us they refer to our notes solely for studying and revision. Immense time, thought and effort have gone into crafting these notes, making sure all ground is covered. The content and layout have all been well thought out for easy learning and reading for our students. The copyrighted materials are crisp and concise, with many summaries given for easy recap. We use pictures, flowcharts, mind-maps and annotations in our notes to facilitate understanding.

The truth is A-level chemistry questions today require higher order thinking skills. You will not see any repeat questions from notes, tutorials or practice papers during the exams. However, fundamental concepts do not change. In order for students to excel in Chemistry, they must be exposed a range of challenging questions that link theory and application.

At Twig Learning Centre, we understand that there are just way too many questions out there. Hence we have done all the work by selecting the ‘must do’ questions of varying difficulty for students to practise so that learning is focused and precise. All questions come with complete step-by-step work solutions so students can follow the thought process in tackling these challenging questions. Materials are reviewed regularly together with the top schools as we adapt to the changes in syllabus and questioning formats. This ensures we stay relevant to the A-Level Chemistry curriculum.


Two interactive SMART boards are used during lessons. It is more efficient as annotations can be done directly on the diagrams. The tutor is drawing directly on the board instead of a laptop and learning becomes more personal and interactive. Videos are also used to show complicated organic chemistry mechanisms and class experiments are conducted to explain concepts. At the end of a long day at school, students who attend our lessons are still able to concentrate and actually enjoy the lessons presented due to the employment of effective teaching aids and tools.

Students only spend 2 hours with us every week compared to 7 hours of chemistry lessons in school but yet, many have commented that they learn a lot more at Twig Learning Center. Learning has been made so much easier and precise with our well-designed teaching methods!


Let’s be frank. Chemistry is not an easy subject to master. The learning curve is steep. There is more content to learn in 2 years of JC than the entire triple science content at O level all put together. Here at Twig, we make the subject easy to manage as concepts delivery is ‘to-the-point’.

Mr Donnell Koh has an exceptional ability in explaining difficult, abstract chemistry concepts in a way that students will come out of the class feeling totally enlightened. Students will learn important key words to explain concepts for application during examinations. These key words are in bold and highlighted clearly in his notes. During lessons he also highlights the common misconceptions that students make in the study of Chemistry. Memorising is kept at a minimum as his teaching focuses on understanding. If the student understands, there is really very little to memorise.

Sometimes, Mr Koh teaches beyond the syllabus, and that allows students to understand the subject more holistically. There is a need for students to see the link between theory and question. Lessons are interactive and all students are encouraged to participate in class. His lessons are never one-way. He is constantly throwing open-ended questions at students during lessons to test their understanding.

Layout of the classroom is spacious and uncluttered, unlike some tuition centres. In fact, all chairs and tables are arranged in such a way that allows the teacher to walk around and monitor the work done by the students. Mini assignments are given to students after every topic and once completed, they are marked and returned to them. This is a form of feedback for students to check on their understanding and ensure that they are able to apply the concepts learnt.

Mr Donnell Koh is an approachable tutor for Chemistry as you can read from the many testimonials. In addition, many students do stay back to ask him questions and clarify their doubts. Donnell will answer queries of all his students no matter how busy he is. Students do look forward to his lessons every week even after a long day in school.

Additional Consultation

Lessons are carried out in a group setting and being a passionate and committed teacher, Mr Koh understands that some students may still have a lot of queries after lessons. As such, he always avails himself for personal consultation should a student need further coaching. All they have to do is make a prior appointment and head down to the centre in the afternoon or before lesson to seek clarification. Otherwise, he can be reached easily via SMS or Whatsapp. Consultations are free of charge as at Twig, we are excited when we see students interested in learning Chemistry and motivated to excel in the subject!

Flexible Schedule

Twig Learning Center understands that JC life is very hectic and students are overwhelmed with school activities, be it sports, societies, or community involvements. We have a flexible schedule with multiple time slots for students to make up within the same week. Hence, if students cannot make it for their usual timeslot, they can always make up on another day.

Crash Courses

There will be crash courses every school holiday in March, June, Sep and Dec. During these crash courses, the important chapters are revisited to help new students to catch up on previous chapters that they missed. This will allow new students to integrate into the existing classes so they can follow the pace of the ongoing classes.

We produce RESULTS

Mr Donnell Koh coaches a few hundred students yearly and 90% of students taught by him have achieved either A or B grades in their A-levels. This goes to show that Mr Donnell Koh has been very successful in what he does.

Many students who were once lost in the maze of Chemistry, after attending Chemistry lessons at Twig, they start to be enlightened and see breakthroughs. Chemistry even became the favourite subject of many. Many have been so inspired by Mr Koh’s lessons, that they went on to further their interest by majoring in Chemistry in the Universities and are doing well now. Chemistry is also a pre-requisite for entry into NUS Medicine Faculty. Mr. Donnell Koh has over the years helped many students score an A after attending H2 Chemistry tuition and that allowed them to pursue their dream to study Medicine

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!!
