No more physical lessons until further notice

Due to the current situation, all lessons are conducted online. For parents and students who are afraid that lesson quality will be affected, no worries. All lessons are conducted 1-1 and quality is not affected. In fact, I have done online lessons on selected students for years and thus have experience. Furthermore, many students have feedbacked that they don't want physical lessons anymore. They want online all the way until graduation. Do contact me for more information. Thank you!

What students say about Samuel

H2 Math and Physics tuition

I would like to thank Mr Li for being so patient & understanding with me throughout these few months of tutoring. He always tries his best to cater to my needs and gives me additional materials to revise for to ensure that I really understand the chapters and makes sure that I have sufficient additional worksheets to do. Not only that, Mr Li makes sure that I fully understand the concepts by making the concepts easier for me to understand and encourages me to ask when in doubt.

Additional Mathematics tuition

Thank you for teaching me and always being so patient with me, especially when I was starting to learn the new chapters and also when I make all those careless mistakes. You are very approachable and friendly, always trying your best to guide me along, allowing me to improve from a F9 last year to where I am now. I am really grateful to have been taught by you and I will definitely do my best to make you proud!

Teaching Style

My teaching style is not rocket science. It has helped many students over the years and I am sure it will help you too.

teaching style fundamentals


I focus on building the basic concepts and prove to students that all questions can be solved using the fundamentals and basic understandings.

teaching style interaction


Teaching is not about me talking and students listening. It is about two-way communication. Both parties asking and answering questions is the best way to learn effectively.

teaching style set goal


I set small and realistic goals with students and review them periodically. This is to ensure that they are on the right path towards their next phase of life.

teaching style applications


I always add in practical applications to what students are learning. Not only does this capture their attention, it makes them remember the concepts better.
