Sean is very enthusiastic in teaching. He makes Chemistry learning interesting and is able to maintain the intriguing level with the students.
The kids have learnt a lot from him and are more confident with Chemistry now.
They have done well in the subject and look forward to attend his lessons every week.
Mrs Sim, Mother of Carmen, Christy, Christopher & Clement
Consistently achieved A grade for O Level & H2 Chemistry after joining Winners Education. 4 of Mrs Sim children have been attending our lessons since 2016.
Although I only joined Winners Education Centre for around a term, Mr Chua has helped me to improve my grasp of chemistry concepts by strengthening my understanding of many basic concepts which helped me to understand more complex ones.
His explanations are very clear and he is always willing to clarify individual doubts during lessons and even through text.
His lessons are always very engaging and his style of teaching really piqued my interest in the subject.
I even started to enjoy it although it was originally my least favourite subject!
Mr Chua offers guidance and encouragement all the way to the end of the A levels which really spurred me on to study harder and smarter!
Despite joining his lessons for less than a year, I already saw improvements in my grades.
Thank you Mr Chua!
Hilary Chia, RI, D to A grade
Before I joined, I was struggling with the large amount of content provided by my school, and it was extremely hard to sieve through my school notes to find what is relevant and tested for A'levels.
Mr Chua's lessons are structured and clear to follow, and his notes are extremely concise, which makes Chemistry less daunting.
I went from a D in prelims to an A in A'levels.
I would recommend Mr Chua's lessons to any student who is struggling with their basic concepts as he mainly focuses on that!
