"Your lessons somehow kindled my interest in Chemistry for me. For someone with consistent fails in sec 3, to constant As in sec 4, the change is miraculous! I can’t exactly pinpoint what changed my mindset but now I find myself enjoying Chemistry. Sean Chua is clear and concise, clearing up many doubts. Not to be overly dramatic but this might have changed my life as I now consider Chemistry as a possible JC course. Fantastic O-Level Chemistry tuition that changed my whole outlook on Chemistry, making it one of my favourite subject!"

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)”

Ruth Ng Hui En, Crescent Girl’s School, C5 (Sec 3 Mid-year) to A1 (Prelims)
