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.

Comfortable, small classes are good! The lessons have helped me pull up my grades from U to B in my prelim examinations! It helped me hone my fundamentals, something the school never emphasized on. The way of teaching is awesome, interesting, enriching and interactive. I do feel confident for A-Level H2 Chemistry now.

The lessons have been very helpful in emphasizing the basics and fundamentals of each topic. This is really helpful because I have always been very weak in Chemistry even in Secondary School. I feel that my understanding of Chemistry has improved a lot. Mr Chua is a really good teacher who is always patient. His thorough explanations help a lot. Thank you!

Chemistry Higher Level Subject grade: 7

I especially enjoyed the functions and graphs workshop as I learnt many different ways to remember the shapes of curves. The workshop allowed me to gain confidence in handling the graph questions in the future. Besides, recaps in basics Trigonometry in O-Level E-Maths also allowed me to be more aware of concepts taught in school that I have yet to grasp. I’d recommend anyone who’s unable to cope with studies to join Winners Education. Thank you Ai Ling!

Doreen Gan | Commonwealth Secondary School | 2014

The workshop explained challenging concepts in simple ways. Along with examples and a variety of questions that tested our understanding of the topic, this workshop helped me better understand the more complex chapters of O-Level E-Maths!

Nicholas Lam | St Gabriel’s Secondary School | 2014

The workshop was fun and enjoyable, I have confidence in my O-Level E-Maths topics now and I have acquired the ability to interpret many shapes and triangles. All the formulas and basic things are now in my head which will help me in my exams soon.

Danny Lim | Woodgrove Secondary School | 2014

When I first stepped into Winners Education, I was an “E8” student and I absolutely loathed A-Maths. But under the guidance of Ms Ong, right now just a few days before the paper, I can confidently say that I will get A1 as a sign of gratitude, for Winners Education is truly one of the factors that made A-Maths one of my favourite subjects now. THANK YOU! Winners Education is a very unique tuition centre, I’ve never regretted joining this family!

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.

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!

Ayo~ Thank you for teaching me Chemistry for the past 1 year. Your O-Level Chemistry class really benefitted me tremendously. I find Chemistry more interesting, enjoyable and understandable after your class. You helped me improve from a C5 to an A1 woohoo. Your notes are really concise and straight to the point and the TYS really benefitted a lot. I like your teaching style because it is funny but at the same time, interesting as well. Really thank you for the amazing 1 year spent with you and the class.

I absolutely loved the A-Maths lessons, and I really looked forward to them every week. Even though there was a little homework given out, and seemingly simple questions at that, the choices in questions showed meticulous consideration. Lesser tutors would have given many questions, choosing quantity over quality. My only gripe is that the lessons were too short. They were really fun.

The lessons were very beneficial. They were entertaining and at the same time educational. I feel that I have learnt much from this entire year. Thank You Ai Ling. If given a chance I will surely join the JC class. THANK YOU!

The lessons have been very beneficial to my studies as I am able to easily grasp concepts that I have trouble with in school. I never really did understand O-Level A-Maths in school so the lessons here cleared up my misunderstandings within a short period of time. The 8 lessons I have attended were really fun and informative. As the lessons cater to smaller groups, I find myself being more attentive. Thus, the lessons were very helpful :D.
Thank You Ai Ling!

The pace of the lessons are appropriate won’t be going on too fast, adapt to the needs of students. Really patient (explain clearly + clarify student’s doubts). Questions prepared in the materials are applicable. Some are challenging, can help students know what they still need to improve through errors they have made. Very helpful, provide extra time to allow students to ask qns (come early & ask in SMS). Really put in great effort with students for them to improve. Good!!

Annie Kwong | New Town Secondary School | 2012

This programme has boosted my confidence in A-Math by reinforcing my concepts and pointing out common errors. I have also been able to apply the concepts to varying types of questions. This is beneficial as it helps me to gain a better understanding and build up my foundation. By reinforcing and enhancing my foundation, this has increased my confidence to do well.

Thank you for taking time to help us with our O-Level A-Maths. You have been very patient and caring and I’m extremely grateful for that.

Hi Sean, just want to say a BEEG thank you being an inspiring teacher. Your passion for Chemistry & dedication in teaching are a great motivation & inspiration to your students. You do not choose only the ‘A’ grade students but inspire them to be. Because of your help, Tim (Timothy) improved his Chemistry and was able to spend more time brushing up other subjects. Thanks! Rgds, Mrs Ho

Flip-charts are very helpful with regards to recall of concepts. The workshop was very effective. Mr Chua was very clear and concise in his explanations of Chemistry Concepts, especially helpful with the Equation Writing & Mole Calculations. Mr Chua has made Chemistry easier to understand with his analogies and more concrete/logical reasoning in chemistry questions. Overall, it was a very conducive and productive use of time.

Thank you Mr Chua. Your coaching helped immensely!

Hi Sean. Would like to share about Zamann’s results. He got a B3 for O-Level Chemistry. Thank you very much for your guidance. From Mid-Year (F9) –> Prelims (C5) –> B3 (O Levels 2009) in just 3 months! Without your guidance, he will not be where he is now. He is eligible for JC and Poly. I sure will recommend you & Winners Education Group to others! =)

Interesting Course! Very good recap on school work and acts as a form of revision so that I don’t have to study Chemistry outside of school. Sean knows how to teach well and can give a very immediate and comprehensive view on many Chemistry queries. He helps by being enthusiatic in answering questions, helping me to spark my interest in Chemistry. Thank you Sean!

Winston Lee | ACS (Barker) | 2009

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.
