Chemistry Tuition

Many have the misconception that memorising alone will get a student to score in Chemistry exams. This is not true at all. In fact, students need to understand the underlying key concepts and present it to the examiners with the required keywords in order to excel in Chemistry.

Systematic Teaching Methodology:

  • Topical key concepts are taught in a simple, clear manner. They are reinforced through carefully selected questions of varying challenge level.
  • Abstract concepts are explained using analogies drawn from everyday life examples, making learning of Chemistry more fun and enjoyable for student.
  • Emphasised on essential keywords that are required by examiners for different type of questions
  • Commonly made mistakes and traps set by examiners are also highlighted to students so that they are aware and can avoid them
  • A quiz will be used to evaluate students’ understanding after completion of a topic. This builds up their competence level one step at a time.

In short, we ensure students truly understand the concepts and their application through questioning, participation in discussion and doing.

The course was very helpful in getting my concepts clear. Mr Chua is a *hyperactive* teacher who is clear and entertaining. He can teach and explain well. He puts in a lot of effort to clarify and check for answers to questions or doubts raised. “

Eveline Tan Sheau Ling, National Junior College, E to A grade

“Sean has made it possible for me to understand certain Chemistry Concepts much better. There are several fundamentals that he insists on me knowing it, that i initially thought of skipping. His analogies and ways of relating chemistry to everyday life is very apt and makes it easier for me to grasp the concepts. With a good grasp of the fundamental concepts, it was so much easier for me to tackle other tough chapters like Acids, Bases & Salts, Electrolysis, Mole Concepts and Chemical Analysis. Appreciate your help Sean! I would highly recommend Sean to you, especially you face problems in understanding those Chemistry Concepts, cos he makes it so simple to relate to. ”

Cheney Wong, St Andrew School, D7 (Sec 4 Mid-year) to A1 (O Level)

"Mr Chua’s H2 Chemistry lessons are the most interesting lessons I’ve been to. He really helps us to get a good grasps of the concepts in each chapter before moving on. He’s always willing to help us clarify any doubts we may have, even via SMS. He is a truly dedicated and hardworking teacher. I’m glad to say that I’ve benefited greatly from Mr Chua’s lessons."

Rashaad Khan, Catholic Junior College, A grade

“Mr Chua (Sean) has made many concepts and topics more understandable and comprehensive. Also, there were many times I had questions that could not be answered by the textbook and Mr Chua (Sean) has always been able to provide me an answer. There were also times where exam questions will come out that were not reflected in the textbook but he has been able to help me understand how to approach the question. I would highly recommend Mr Chua (Sean) to those that face challenges with Chemistry Concepts because he is a good coach and he truly deserves it. He is also the type of person who encourages and gives direction to students so that we not only learn to overcome the challenges but learn to love them.

Thank you Mr Chua (Sean) for helping me inculcate a great love for the sciences (yes, not just Chemistry)! I truly appreciate all your help, because I believe that the passion of my studies that you have helped me developed will bring me to great heights in life. Thank You and never stop teaching cause it’s what you are good at Mr Chua (Sean)”
