Looking for help to improve your child’s Chemistry results this holidays?
Or looking to strengthen their foundation to cope with next year curriculum?
Most of the time, the solution is straightforward.
Basic Concepts + Associated Keywords + Mapping Techniques.
Many Sec 3 students did well in the first few tests but did badly for their finals.
Many students claim that they know their work.
But whenever I review their exam papers, their answers is evidence of memorising rather than understanding.
Students who are aiming for A1 for their O-Level Pure Chemistry or IP Chemistry must set their Sec 3 foundation strong. This is the reason why we have selected 5 very important topics for our revision workshops.
- Chemical Bonding
- Acids,
- Bases,
- Preparation of Salts
- Mole Calculations
How important are these topics?
Look at the diagrams to see how they’re closely linked to other Chemistry topics.
Some topics aren’t familiar to your child as they will only learnt them in Secondary 4 or Year 4.


How will my Revision Workshops benefit your child?
The Revision Workshops will get your child to gain the momentum and confidence to:
- Revise comprehensively on key essential concepts on a topic – by – topic basis.
- Gain a better understanding of the topics.
- Interlink the relationship between different topics.
- Apply concepts on higher order thinking examination questions.
We know it isn’t easy for students to accomplish all the mentioned by themselves, with distractions from instagram, handphones, TV, friends, going out, no interest in subject, almost totally giving up on the subject…
Please note:
- I am not a school teacher so I do not expect your child to show up and simply listen. I conduct the lesson like a conversation – engaging, lively and memorable. I ask questions and I highly encourage your child to ask questions anytime too! Interaction is the only way to open up your child’s mind especially if Chemistry is not their favourite subject.
- I need time for your child to understand and not memorise the concepts. To interlink the relationships clearly. To gain the confidence in answering questions. I do not force information down their throat.
- I cover everything in depth. From essential concepts to answering techniques using the correct keywords. When your child gives their 100% attention and participation during the workshops, they will have the skillset to answer questions in the topics.
- To ensure you see a drastic improvement in your child’s next Chemistry exam, you are responsible to ensure your child clarifies with me when in doubts and applies what they have learnt. While I get them to understand the essential concepts, provide the channels for them to clarify, give them exposure to questions of varying challenge level, don’t you agree your child still needs to put in the effort as well?

What Other Students & Parents Say About Us
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. 4 of Mrs Sim children have been attending our lessons since 2016.
Really appreciate how Mr Sean Chua emphasizes the need to understand Chemistry concepts rather than memorizing them. I used to think that Chemistry was a very difficult subject due to the fact that the questions have a high tendency to cross topics. I was always very confused at these seemingly random questions that came out of nowhere. However, through Mr Chua’s clear, logical and concise notes, teachings and explanations, I find myself having more fun than stress learning Chemistry. Really thankful for Mr Chua for changing my perspective of Chemistry.
Ngo Zun Yin, Gan Eng Seng School
Consistently achieved 80+%. Admitted into 1st choice – RI.
Mr Chua is a very dedicated tutor and he knows the trend of exam questions very well. The workshops we had also help a lot especially during O’ levels. With this, it helped me gain confidence in asking and answering questions in chemistry without needing to depend too much on memorization. It helped me focus more on setting my basic skills, putting in the right keywords and being able to apply it on different application questions correctly through the B.A.M technique. Thanks to that, I got A1 for chemistry!! Will definitely recommend!!
Aiko Tiranya, St Margaret
Breakthrough to achieve A1 for O Level Pure Chemistry
I joined Mr Chua from the beginning of Year 3. He has since been able to cultivate a strong interest and love for Chemistry in me. During each and every lesson, he is very lively and enthusiastic about passing on his knowledge. He consciously makes the effort to cater to his pupils’ needs e.g. via ensuring that each lesson is conducted a suitable pace.
I would definitely recommend Mr Chua as a Chemistry tutor.
Erin Lin, RGS (IP Chemistry)
Consistently achieved 80% – 90+%
Enrolling into Mr Chia’s Chemistry class is certainly a good choice because Chemistry is no longer a boring subject to me. Mr Chua is a very dedicated and inspiring teacher with undying love for imparting his knowledge. He would always go the extra mile with the student’s interest at heart. Notes provided are comprehensive and easy for revision. He has unique teaching techniques enabling students to grasp and understand concepts effectively. I am truly grateful and blessed for having Me Chua as my Chemistry teacher. Thanks for being so awesome!
Charlyn Yeo, Nan Chiau High School
A1 grade for O Level Pure Chemistry. In NYJC
Before joining Mr Chua lessons, I used to struggle with chemistry and did not know how to answer questions effectively. Mr Chua’s unique teaching method enabled me to have a more in-depth understanding of the curriculum content in Sec 3 and 4 which allowed me to have a strong foundation in Chemistry. Once I mastered the basics, I was given many application questions and I soon learnt how to answer them confidently. Thank you Mr Chua for being a caring and patient teacher for these past 2 years!
Gregory Tan Jie Hui, NJC (IP Chemistry)
Consistently achieved 75% – 90+%
Before joining Mr Chua’s workshop I often doubted myself when completing questions & lacked a clear thinking process. During the workshop, Mr Chua was engaging and straight to the point, and I found unique ways to remember key concepts. After completing the workshop, I am now faster and more confident when solving questions. Mr Chua’s lessons & workshops would be fun yet enriching for everyone.
Shermaine Lim, Chung Cheng High School (Main)
Mr Chua is patient and explains concepts well. I went from D7 to getting an A2 for O levels!
Joshua Ng, Queensway Secondary School
D7 to A2 for O Level Pure Chemistry, attended lessons online for the entire year
Although I have only been going to Winners Education for half a year, my results have improved tremendously.
Mr Chua is an amazing teacher who is able to get the full attention of his students during lesson and is able to make chemistry more interesting for them. He ensures that all of his students understand the concepts well instead of making them memorise the content which allows the students to be able to tackle harder questions as they have a strong foundation of the subject. I would strongly recommend this tuition centre for anyone struggling with the subject.
Mayukhi, SCGS (IP Chemistry)
Fail to 80%
Mr Chua was recommended to me by a friend who knows many tuition agencies as a caring and dedicated tutor who really helped his students improve. My son doesn’t like tuition generally but finds Mr Chua’s lessons interesting. He even recommended his elder brother doing A level Chem to attend the lessons, and my elder son found it very useful too. Will recommend to all my friends
Eileen Yee, Mother of Luke Yang & Jerry Yang, ACSI & TMJC
Before joining Mr Chua’s classes, I have always struggled with Chemistry and was constantly getting D7 to F9. I never understood how to apply the concepts to answer questions, especially when questions cross topics. I have always thought that Chemistry is all about memorising the concepts and their examples.
However, after attending Mr Chua’s classes in June, all the concepts from the various topics began to make sense on how they can be related, and answering cross topic questions became a breeze.
Moreover, like what Mr Chua always emphasise, I found that there is only one small portion that requires memory work. I really appreciate how Mr Chua explains the concepts so clearly using his short yet detailed notes.
I am grateful that Mr Chua changed my mindset for Chemistry within a mere 5 months, giving me the extra motivation to work even harder, and thus allowing me to get a distinction for my O levels
Andrea Chin, Crescent Girls School
D7 to A2 for O Level Pure Chemistry
My daughter has been attending Sean’s class since Sec 3 and i observed that she has gained much confidence in Chemistry. She looks forward to attending the class as the sessions are engaging. Apart from classroom learning, she is also able to consult Sean through WhatsApp. This definitely helped in her learning and she has obtained consistently good results. I highly recommend the centre for Chemistry tuition.
Stacey, Mother of Heidi Ng, St Theresa Convent
Consistently achieved A1 grade for O Level Pure Chemistry after joining Winners. In NJC.
Sean is a very good teacher. He is extremely helpful, patient and passionate in teaching, and played a huge role in my daughter’s O-level pure Chemistry study success. He not only helped her achieve desirable results, but also made her realize that Chemistry is tolerable and not as boring as she always deemed it to be. He also provides timely feedback and useful advices to me, enabling me to fulfill my role as a parent in aiding my daughter’s study. I highly recommend the Centre if you are looking for a reliable partner during your son or daughter’s Chemistry learning journey.

How is the workshop conducted?
We adopt the BAM!™ methodology as illustrated:

The first part of the workshop will be used to build Basic concepts and understand Associated keywords to ensure that every student is equipped with a strong foundation of essential concepts to cope with answering examination questions.
After which, the remaining time shall be set aside to impart the Mapping and application of basic concepts and associated keywords to solve carefully selected examination questions. Problem-solving strategies will be taught during the workshop in a clear and systematic manner. All materials have been carefully prepared by our trainers through cumulative years of research and observing the trends of the past years examination questions.
All workshop participants will be provided with customised learning materials for each workshop.
There will be a 5-10 minutes break every hour for students to use the washroom and access their mobile phones.
Who is the teacher?


Sean Chua
Mr Sean Chua is
- the only Chemistry specialist since 1999 who is
- the invited book author for BOTH the O-Level Pure Chemistry and A-Level H2 Chemistry Ten Year Series.
This also means your child can have direct access to him for discussion on his approach in solving each and every single question from the Ten Year Series.
He is also the rare few Chemistry tutors who is familiar with BOTH the O-Level and A-Level syllabus which is the reason why IP Chemistry students benefit greatly from his Chemistry tuition classes.
Most school teachers and private tutors only know either the O-Level or the A-Level Chemistry syllabus. For Sean, his experience and mastery of both the syllabuses allow him to connect the basic concepts in GCE O-Level Pure Chemistry and the advanced concepts in GCE A-Level H2 Chemistry together. This allows students to understand the essential concepts thoroughly, just like a crystal ball in their hand. For O-Level Pure Chemistry students, there are concepts and phenomenon which their school teachers want them to just memorise it. When asked, the teachers were not able to explain further. This is where Sean comes into the picture where he uses advanced chemistry concepts to explain clearly to students the real reason and concepts so that they truly appreciate it.
Being a certified Neuro-Linguistic Practitioner (NLP), Sean communicates effectively to his students and changes the students’ perception towards Chemistry; from initially dreading the subject to gradually finding more interest. He believes his NLP skills play a major role in unlocking the superpowers in his students to score in Chemistry and enjoy learning.
Many who came to us are low in confidence for Chemistry and Sean always have his way to encourage and motivate them to relearn Chemistry and do their very best. About 70% of our students are recommended to us, from our ex students and their parents, from private tutors and school teachers. This differentiates him from Chemistry teachers and other Chemistry tutors.

Who can attend the workshops?
The workshops are for
- Underperforming Sec 3 & Sec 4 O-Level Pure Chemistry & IP Chemistry students who have the grit to do much better but lack the skills and proper guidance.
