2020 Sec 3 Sec 4 O-Level Pure Chemistry Weekly Tuition Class

“I want my child to build up a strong foundation in his Sec 3 Chemistry so that it will be less stressful for him during O-Level.”

“He goes to a tuition centre with his classmates but I don’t see any improvement for the past 6 months.”

“My child knows the concepts but she can’t seem to be able to score her Chemistry exams, always borderline.”

Just like Art, Chemistry is abstract.

But when your child is shown how learning of Chemistry is actually about everything around them instead of just loads of meaningless information being forced down their throat , they start “seeing” Chemistry, showing more interest and motivation to learn more.

It takes more than 20 years of experience, effective communication skills and a magic wand to unlock your child’s potential to pass Chemistry with distinction.

Mr Chua “breathes Chemistry“. 4 years of National University of Singapore Applied Chemistry honours course and his job stint at a Chemical MNC have provided him the relevant analogues, everyday life and industrial examples to make Chemistry easy to understand, interesting and memorable for your child.

“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, because he makes it so simple to relate to.”

Cheney Wong | St Andrew School | D7 to A1 grade

Even Google recognises Sean Chua as the authority associated with learning and scoring in Chemistry.

Do you want your child’s learning to be aligned to the latest examination trends so that they can pass Chemistry with distinction?

Mr Chua is the only Chemistry specialist who is invited by SAP publisher to author both the O-Level Chemistry and A-Level H2 Chemistry Ten Year Series. So he’s constantly updated with the latest exam trend, so will your child.

“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!”

Bryan Leong | Hwa Chong Institution | F9 to A2 grade

Only a Small Class Size of 20.

We intentionally keep our class size small so that we can deliver our promises to you and your child.

Mr Chua believes that small class interaction cultivates active learning, inspire action and motivate your child to achieve results faster.

Less is More Learning Materials.

Mr Chua’s “Less is More” learning materials is an important factor how your child can make a jump of 2 to 5 grades within weeks.

As a Chemistry specialist since 1999, Mr Chua has a valuable collection of Chemistry questions, meticulously sorted out into different topics and challenge levels. Your child will be exposed to a wide variety of questions, helping them to be more flexible, confident and prepared in answering any questions.

The notes are customised such that they are easy to understand and serve as a good summary for your child just before their tests and examinations.

Just like his students, your child will love his bullet-point notes with emphasis on keywords which will score them the full marks in their structured questions.

Mr Chua also likes to use flow-charts so that your child can inter-link all the concepts and topics in a bird’s eye view.

We Support Your Child Beyond the Class.

Mr Chua encourages asking of any questions anytime – before, during and after class. To see results fast, your child needs to clarify.

Our classes are scheduled with 30 minutes apart to give your child the time to ask, unlike many centres which have back to back classes.

Your child will also have the privilege to WhatsApp Mr Chua anytime and receive a fast response from him personally.

We Involve You.

Since we only see your child 2 hours weekly, there are some aspects of learning which you must enforce at home.

We will keep you updated of your child’s learning progress every 2 to 3 months – your child’s quiz results, exampaper analysis, O-Level timetable, the strategy to pass Chemistry with distinction.

You can also reach Mr Chua directly if you have questions or feedback.

Parents are “the most important stakeholders”, says Education Minister Ong Ye Kung.
The Straits Times 29 September 2018 “Parents must play a part in helping their child to discover the joy of learning

O-Level Chemistry Tuition Sunday Class Bernessa Ang
Bernessa Ang | Anderson Secondary School | F9 to A2

While other tuition centres brag about having 500+ students every year, we count our blessings that 70% of our students are referred to us and every student looks forward to attending our lessons despite seeing the same face, hearing the super energetic voice and getting charged up on the mind-blogging chemical questions, year after year.

We have worked with more than 1600 students so we totally understand your child might have mind of their own.

Attend our satisfaction guarantee trial lesson.

Doesn’t like Mr Chua’s teaching? We will refund you the fees within a week and your child keeps the materials.


Sean is probably 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 allows 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 enjoy learning and scoring in Chemistry.

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.

“I feel that the O-Level Chemistry lessons have been very effective and has helped to grasp the basics of Chemistry and letting me realise that it is actually quite easy and I hope that this programme will be carried on for future years. I also find Mr Chua an effective and dedicated teacher, even staying back after class to help me.”

Ethan Lim | St Joseph Institution | C6 to A1 grade 

“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 or 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!”

FAQ (Click on + sign to read the answers)

What happens when my child is unable to attend a scheduled lesson?

He has to WhatsApp us at least 3 days before his scheduled lesson to attend another class within the same week. If he is unable to attend the alternative class or that class is full, an email follow up will be sent and your child may make an appointment to come 30 minutes earlier on his next lesson to clarify his questions with Mr Chua.

Are the classes suitable for IP students?

Yes. Most IP schools conduct the O-Level syllabus with additional concepts from A-Level H2 Chemistry.

Depending on the depth of the A-Level H2 Chemistry concepts added, your child will be advised of either a 1 to 1 consultation with Mr Chua or to attend a JC 1 class for selected topics. Both arrangements are complimentary.

Over the years, we have IP students from

  • ACS Independent,
  • Catholic High School,
  • Cedar Girls’ Secondary,
  • CHIJ St Nicholas Girls’ School,
  • Dunman High School,
  • Hwa Chong Institution,
  • Nanyang Girls’ High,
  • National Junior College (secondary section),
  • Raffles Girls’ School,
  • Raffles Institution,
  • River Valley High School,
  • Singapore Chinese Girls’ School,
  • Temasek Junior College (secondary section),
  • Victoria School

Since 1999, Mr Chua has taught more than 1650 students from almost every school and being the Ten Year Series book author for both O-Level Pure Chemistry and A-Level H2 Chemistry, he is very familiar with the both the syllabus of O-Level and A-Level Chemistry. IP Chemistry students will learn the basic concepts similar to O-Level Pure Chemistry students with additional A-Level H2 Chemistry concepts taught. Also, some IP schools emphasise more on application questions in their examination and all these will be addressed in our Secondary 3 and 4 Pure Chemistry tuition classes.

Our fast track programme welcomes IP Chemistry students as young as Secondary 1 to start in our Secondary 3 Chemistry classes. Due to the structured teaching methodology by Mr Chua, IP students who start early tend to enjoy learning and build stronger foundation in Chemistry.

*Book a trial lesson means the fees is $120 for a lesson with satisfaction guarantee. If your child is not happy with the lesson, we will refund you the fees and your child can keep the learning materials.

*Only applicable to new students who haven’t been taught by Mr Chua.

How is the lesson conducted?

Every lesson is conducted in a systematic and enjoyable manner. Learning in a structured and systematic approach sets the foundation which allows underperforming students to make massive improvement in their grades, from F9 to Distinction.

Mr Chua’s strength lies in using everyday analogies to simplify abstract Chemistry concepts for his students. This is probably one of the reasons we have many students who have been with us from their Secondary 3 to JC 2. They look forward to the lessons week after week, year after year.

The basic concepts for each topic will be taught so students who have not learnt the topic can follow. For students who have learnt the topic, it is a great time to recap and reinforce their understanding by clarifying their doubts. Yes! We encourage asking of questions in class. Techniques on solving carefully selected application questions (MCQ and structured questions) will then be taught.

As we have only a limited 120 mins every week, everything taught is delivered with precision and clarity. It’s always about achieving maximum result in minimum time under the guidance of an experienced teacher, Mr Chua.

My child joins Winners Education late, can he catch up?

When there’s a will, there’s a way.

Your child can clarify any doubts with Mr Chua personally via WhatsApp/SMS support on a 24/7 basis.

He can also arrange to see Mr Chua before or after each lesson for individual consultation.

If your child is in Secondary 4 now and there are many topics which he is facing challenges in, we strongly recommend that he joins the Secondary 3 class on top of the Secondary 4 class.

Every June and December holidays, we will also be conducting our essential Topical Chemistry Revision Workshops to help students to strengthen their concepts for the major topics. Your child can consider these revision workshops if they join our regular tuition classes much later.

All these learning platforms means that your child will always have a chance to learn all the essential concepts from Mr Chua.
