JC A-Level H2 Chemistry Tuition Testimonial of Cyril Teo HCI 2018

A-Level H2 Chemistry Students Testimonials

Mr Sean Chua is a very effective Chemistry tutor and under his guidance, my son’s interest and understanding for the subject has grown in leaps and bounds. Sean’s teaching style has helped my son’s grade to improve by a lot and score A for his GCE A Level exam this year! Thank you Mr Sean Chua for your patience and dedication!

Fiona Loh, Mother of Nicholas Chin, ACJC 2021

Nicholas is applying to NUS Medicine to pursue his interest.

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.

Chem had always been my weak subject ever since Sec 3. My foundations in the subject were weak which made it difficult to quickly grasp the new concepts taught at the JC level. As such, I really struggled with getting good grades in JC. I received an S grade in the mid-year exams followed by an E grade in the promotional exams.

Upon the recommendation of a friend, I decided to join classes at Winners education in order to build my confidence in the subject. The chem classes delivered by Mr Chua were very clear and concise. He made even complex concepts simple to understand. His notes would condense the topics into salient points which greatly aided in revision. I managed to clarify my doubts and strengthen my foundations in chem through asking questions throughout the lessons.

It took me approximately 6 months to improve my results and to eventually attain a B grade at the Prelims. I then went on to attain an A grade at A level Chem. I realised that it is never too late to start catching up on things that you do not know and to improve your understanding in a subject. Winners education certainly helped in my journey but I also needed to put in regular hard work to get the results I wanted.

I would recommend Winners to anyone who really wants to improve in Chemistry or Maths and wishes to do so in the fastest possible time. Ultimately, it doesn’t matter how you started or what happened in the middle. What matters is how you end your journey. 🙂

Aaron, RI 2020

E 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!

Kok Chu Shuen, VJC 2020

E to A grade

I have been with Winners Education Centre for three years and I am extremely satisfied with their way of teaching. Before I joined, I struggled with basic concepts, let alone application of those concepts. I was unable to overcome my misconceptions by myself as I did not know the correct way to study Chemistry. I thought Chemistry was a subject you just had to memorise to score A’s. I was getting D’s before I joined and decided to join Winners as the tutor, Mr Chua, seemed very confident and humble about his concepts. He was also the author of the Ten Year Series. I loved Mr Chua’s classes as he always made concepts seem simple and straightforward. His lessons were engaging and taught me the fun in Chemistry. I became more daring and answered more questions as well. I managed to achieve a A in H2 Chemistry after 2 years of JC.

I would recommend this to anyone who is struggling with H2 Chemistry and is looking to clarify all his basic concepts. To all students taking H2 Chemistry, good luck and try your best! Always stick to your basic concepts and do not be afraid to seek help as help is always here for you. What matters is how badly you want to do well.

Tay Yang Ying, NJC 2020

A grade

I hadn’t quite been failing Chemistry before going for Mr Chua’s Organic Chemistry revision workshop but I wasn’t really doing super well either because my content knowledge was all over the place. It gave me a peace of mind and sound revision materials for me to efficiently absorb all that I needed to get an A in H2 Chemistry and full marks for Paper 1! I had attended his classes in secondary school too and gained a love for the subject so thank you Mr Chua!

Bernadette Fong , EJC 2020

D to A grade

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 2019

Mr Chua’s lessons were engaging yet informative and I personally benefitted a lot from his lessons. His enthusiastic personality makes the classes enjoyable and piqued my interest in chemistry. Mr Chua is also very kind and helpful, ensuring that all students understand each concept fully, not just memorizing the steps to get the answers.

Jaryl Ong, HCI 2017

E to A grade

When I started JC, chem was a subject that i really tried my best to avoid studying because i struggled with it so much and it was pretty obvious from my grades (I got a U for CTs in year 5).

However, Mr Chua’s lessons really changed my whole attitude towards the subject because of his emphasis on the importance of mastering the basics and getting our fundamental concepts right before moving on to tackle questions and that really helped me in overcoming my fear of the subject I feel.

Not that anyone cares but I ended up getting an A for chem in my A levels which is a pretty big improvement from my U in year 5 so ya THANKS MR CHUA !!

Puar Yu Rou, RI 2017

Mr Chua is a dedicated teacher who strive to help every student attain their desired results. His unconventional teaching methods greatly helped me grasp difficult Chemistry concepts. His passion for Chemistry has inspired me to pursue my own interest in the subject. Will definitely recommend to those who need the extra push in the subject.

Cuithbert Lim, MJC 2017

D to A grade. He was a Combine Science student during O Level.

Learning chemistry from Mr Chua has been incredibly helpful because he makes the concepts easy to grasp and he understands that knowing the basics is very important. He is also willing to answer any questions students have either in person or through what’s app which is really great. I definitely recommend his classes for anyone who is struggling or needs a little help for chemistry!

Shauna Tan, Temasek JC 2017

C to A grade

“She likes it that she can clarify her doubts and get her questions answered in the way she can understand”

Winners Education was first introduced to me by my brother who had attended class there a few years before me.

Before attending class here, I was struggling in school with so many concepts that I could not grasp.

Winners Education is different from many other tuition centres that I have been to because they do not try to beat the schools in teaching content. The teachers at Winners Education focus on ensuring students can understand topics well instead of focusing on just covering topics quickly.

Every lesson was dedicated not so much on content dissemination, but more for asking questions and clarifying doubt. Most importantly, Winners Education always made sure everyone was on the same page and everyone understood fully before continuing with teaching content.

The centre is most suited for students who find it hard to keep up with the pace at school and have not fully grasped their concepts yet. Even though it may seem like content is not being taught as quickly, every lesson is a form of revision for the chapter and students will eventually require less time for final revision at the end of the year.

Winners Education helped me to improve my Chemistry grade until I eventually scored an A in the ‘A’ level examinations.

Thank you so much for your help for the past 2 years, answering all my queries and misconceptions. Wouldn’t have been able to do it without your help, Mr Chua!

I would certainly recommend this centre to everyone.

Mrs Lee, Mother of Lee Qi Zong, NYJC 2012

Joined us since Sec 4. Consistently achieved A grade for O Level Pure Chemistry & H2 Chemistry after joining Winners.

Before I joined Mr Chua’s lessons, H2 Chemistry felt really hard and although I could understand my school’s lectures, I couldn’t seem to apply the knowledge and answer my tutorial or examination questions well. I was scoring Us and Es all the way till around mid J2. Fortunately, after join Mr Chua’s lessons, Mr Chua was able to explain the concepts much more clearer and helped me to understand how I should apply the concepts, helping me to score a B at the A levels. He was engaging as a teacher and showed care as a mentor to his students.

Jesper Loo, RI 2020

U to B grade

I would like to thank Mr Chua for helping me to efficiently understand and absorb chemistry!

Chemistry has been my weakest subject in JC and rote memorisation was going nowhere. With 4 months left to A levels, I decided to enroll in Mr Chua’s lessons and improved by 5 grades from Prelims to A levels. What you can expect is easy to understand notes, accessible lessons online and a welcoming teacher. If you are currently struggling in chemistry, this is for you. :>

Josephine Tan, TMJC 2020

E to B grade in 4 months

In the months leading up to A levels, Chemistry was a struggle. Grasping content wasn’t the problem, but answering questions using the knowledge acquired was. Mr Chua’s effective pedagogy methods enabled me to develop critical thinking skills by constantly drilling us with new question styles during class. This has helped in allowing me to remain calm when answering what seems to be a challenging question in the examination. In the months leading up to prelims, it was difficult to score well, and i constantly got D grades for chem. After joining a few weeks before prelims, i could feel improvement which led to a better result of a B in the A levels.

Jerry Yang, TMJC 2020

D to B grade in 5 months

This tuition centre has rly helped me out in the last minute lead up to As! Even though I joined in the last month, I was given adequate help and the opportunity to consult Mr Chua for any queries regarding chemistry, both after class and even through PM on WhatsApp. Mr Chua is also rly engaging and enthusiastic in his classes which I really think makes his lessons easier to follow.

Benjamin Yew, RI 2019

S to B grade

Learning under Mr Chua has been a great help and he has helped me boost my grades due to his persistence on understanding concepts instead of memorizing them. All in all, the tuition is great for anyone struggling to understand chemistry in A level!

I really enjoyed the learning experience provided by Mr Chua here at Winners Education Centre. Before I joined this centre, I was an unwilling student who thought that learning Chemistry was a waste of time and that I wouldn’t need it after my JC education. However, under Mr Chua’s guidance and teaching, I learnt to understand the nuances behind Chemistry and its interconnectedness to other aspects of life. I developed an interest in Chemistry, which led to me improving and achieving my desired results.
