Clarence has a vast and complete understanding of all H2 Mathematics material and more. But what differentiates him from the rest of the tutors I had, is that he is able to explain the most difficult of concepts extremely simply. He drew simple diagrams, used simple words, and even the hardest and most intimidating problems unweaved before me into their basic concepts in a matter of minutes.


He is a genius at teaching. His amazing abilities, coupled with his friendly personality and extensive notes, made H2 Mathematics easy and actually enjoyable. 

Under his expert tutelage I found myself not just memorizing. I was learning. I couldn't recommend him enough.

No lesson time is wasted with Clarence, as he is able to consolidate key concepts and ideas of any topic quickly upon demand! The toughest problems you throw at him is unraveled within seconds -- often even before he is done reading the question! 

As for key to securing an A, Clarence advocates students to learn by understanding, instead of rote learning or 'studying blindly'. 

It has changed my whole perspective of JC education. 

While still indulging in my favorite games, manga, gym and sports, I went from S & E grades for H2 Math and H2 Physics common tests and promotional exams in Year 5, to double Aces in both subjects at 'A' level exams. 

I guess, that says it all.

Before I engaged Clarence as my tutor, I faced difficulties keeping up with syllabus and the pace of teaching in school. I was extremely unclear of the concepts. I consistently obtained only D grades for my Math exams. However, with Clarence’s patient guidance, it was much easier to visualise difficult topics like Vectors and I improved at a tremendous pace.


Clarence’s teaching style worked very well for me, because he customised lesson to our needs and pace. He categorised questions according to question types and difficulty. This made it much easier to recognise the common question styles when they appeared in our examinations and tests. He is able to teach a brand new topic within at most 2 lessons by giving us his own personal handouts and worksheets and gives us a very clear concept check of the things to take note for every chapter of the syllabus...


Classes with Clarence are extremely enjoyable and I often look forward to them as he had the ability to engage us in Math and joke around appropriately, making time past fast yet meaningfully. He is a very dedicated teacher, who ensures that we are clear of the lesson’s main teaching points before he ends class...


With Clarence’s help and guidance, I obtained an A grade for H2 Math in the 'A' levels. Thanks Clarence!

Clarence is genuinely the best tutor that I have ever had for Physics. He is always so patient in explaining Physics problems to me regardless of how long I take to understand them, with his main priority being that I can eventually grasp the concept.


As he is very approachable, I never hesitate to clarify my doubts about Physics which really facilitates my learning. Clarence makes Physics an enjoyable subject, and he helped me gain confidence in it despite my initial fear of the subject.


Despite his many accolades, Clarence is really very humble and modest and always seeks his best to improve his teaching for his students.


Most importantly, he caters to the individual needs of his students such that our learning becomes personalized. At the same time, Clarence also helps analyse his students' weaknesses so that we are able to work on these areas for improvement in our grades.


His warm teaching style coupled with his natural aptitude in Physics really makes him the best tutor ever, especially since he is always willing to give his best for his students.


Under his guidance, I eventually achieved an A for Physics in the A level examinations! I would definitely recommend Clarence to anyone who requires help in Physics as he can help them achieve a significant jump in grades and also enable them to enjoy the learning process.


Once again, thank you so much Clarence!
