Here are some words from our students
In the middle of the year, my Chemistry grades were at an F9, and I was having significant difficulty understanding the different topics. When I started lessons with Ken Yi in May of Sec 4, he was incredibly helpful. He explained the topics clearly and provided excellent materials that made studying and understanding much easier. As a result, my grades improved to a C6 in the prelims and a B3 in my O Levels, which was a huge improvement from where I started earlier in the year! Thank you Ken Yi!

When I first met Ken Yi at the end of Y5, I was struggling massively with Chemistry. Ken Yi went out of his way during the December holidays to go through concepts that I was not able to grasp fully so that I could enter Y6 without needing to worry about my fundamentals.
In addition, the notes provided by Ken Yi further helped me in understanding the different concepts which we were required to understand. Throughout Y6, Ken Yi always kept his faith in me and continued to give his best when helping me.
From struggling with Chemistry, Ken Yi had helped me achieve a grade 7 during my IB

Mr. Ken Yi makes lessons both engaging and interactive. His lighthearted teaching style creates a positive classroom environment that students find hard to dislike. At the same time, he maintains a strong balance between academic rigor and intensity, ensuring our learning progresses steadily. He often moves slightly ahead of the school's syllabus, keeping us ahead and allowing plenty of time for focused revision before the end-of-year exams. He’s also willing to split the class to provide more personalized attention to students struggling in certain areas, even offering extra lessons if needed. Furthermore, he sets high but reasonable standards, motivating his students to push themselves and reach their full potential.

I started chemistry tuition with Ken Yi shortly before my Year 5 promos, and he played a crucial role in deepening my understanding of chemistry concepts. He even went over chemical bonding with me four times to clear up my confusion. His lesson notes were both detailed and concise, helping me grasp each topic thoroughly rather than relying on rote memorization. The topical revisions were a game-changer, equipping me for all possible question types. Ken Yi is an incredibly patient and passionate teacher, and I truly believe he made chemistry more enjoyable for me while ensuring consistent performance throughout my IB journey!

Before joining Mr. Ken Yi’s classes, I had never passed a single Chemistry exam. However, his clear teaching style and flexibility helped me make huge improvements in my grades. He didn’t just break down the concepts, but was always available for consultations, whether in person or online. He quickly clarified any questions I had, which made a significant difference in my understanding. Thanks to his support, I went from failing every exam to achieving an A2 in my O-Levels. I’m truly grateful for his dedication and for making Chemistry both manageable and approachable.

When I first joined Ken Yi's class, I was struggling with my Chemistry at the end of year 5. Although I felt that it would be too late to catch up by my IB, Ken Yi provided a lot of help for me to improve and catch on past content that I was struggling with.
He also always replies to my many questions very promptly and his explanations are very clear and easy to understand. I am very grateful to Ken Yi for saving my Chemistry.

Ken Yi is an amazing tutor and was nothing but guidance and support throughout my IBDP journey and I am so thankful to have him as my tutor. When I first met him, right off the bat I could tell he was dedicated and passionate in teaching, genuinely wanting to see me succeed. During class, he is thorough in going through the content and explaining any unfamiliar concept with precise and exam-worthy answers. Unlike most, he ensures I understand the key concepts and ideas; not robotically and meaninglessly memorise content. With that, my attitude towards chemistry was nothing short of enthusiasm and motivation to excel in the subject. Out of class, I could always refer to his notes for anything I needed the extra revision on and he is also swift to respond in text to any difficulty I have with my homework, IA or just my understanding of concepts.
​
He initially was a private tutor thus giving his 100% towards me, yet even after opening his centre, I never felt that anyone was receiving less than his 101%. He takes his time in class to ensure that everyone understands the content and no one is behind.
​
Moreover, the class environment was extremely comfortable as he often encouraged questions and re-clarifications by his students as well as engaged the whole class by challenging our knowledge to enable discussions on important topics. These lessons were fun with some off-topic banter and conversations, lightening the mood and easing the stress of studying for the exams.
​
He made it easier to revise without the burden of worry. In the end, I easily grabbed my 7 thanks to his help and commitment towards educating his students. Thank you, Ken Yi!

I am immensely grateful for the guidance and support provided by Ken Yi throughout my A-Level journey. His expertise in the subject has been instrumental in helping me achieve an A grade in H2 Chemistry.
​
He was able to make complex concepts easily understandable through clear explanations and illustrative examples. His notes are also clear and concise and focus on the key learning points for each chapter which makes revisions so much easier. He always goes the extra mile for his students, from having online lessons for days we couldn't make it to the physical centre to having extra consults before papers.
​
One aspect of his teaching that I truly appreciated was his commitment to fostering a supportive learning environment. He always encouraged questions, welcomed discussions and addressed any doubts or misconceptions which created an atmosphere where I felt comfortable to deepen my understanding of chemistry. Overall, he genuinely just wants his students to do their best and will consistently go above and beyond to ensure their academic achievements.

Ken Yi played a pivotal role in my success during the IB journey, guiding me to achieve a grade 7. Transitioning from the O-Level program to HL Chemistry presented a significant challenge for me, as I grappled with the intricacies of new concepts. Ken Yi's expertise was evident as he adeptly simplified complex ideas, facilitating my comprehension of theoretical aspects. His responsiveness outside of class, promptly addressing my queries via WhatsApp,
was also immensely valuable.
Beyond his academic proficiency, Ken Yi goes beyond the role of a tutor, fostering a friendly and supportive connection with his students. I am truly grateful for the learning experience he provided, aiding greatly in my academic growth,.

I had the pleasure of working with Ken Yi for my two sons' O-Level chemistry studies. I can confidently say that Ken Yi has made a great impact in improving their grades. His ability to break down complex concepts into understandable components has been invaluable.
​
With his guidance, I saw a significant improvement in the boys' grades and their overall comprehension of the subject. Ken Yi was like the big brother to the twins who obtained distinctions in chemistry. His patience, enthusiasm, and encouragement made a significant difference in their learning journey.
Elsa
Parent of O-Level student in 2022
Ken Yi has been nothing but a great help to me throughout my IBDP HL chemistry journey. Joining him in Y6, my understanding of HL Chemistry was a huge mess due to the quick pace of lessons in school as well as having shoddy private tutors prior. I thought my chemistry knowledge was okay, but going for Ken Yi's lessons helped me to rethink how much I knew and understood about HL chemistry. Ken Yi's effective and concise notes as well as his well-thought-out assignments helped me slowly inch my chemistry grades ever closer to a 7.
​
Before Ken Yi, my Chemistry HL grade was at a 3, but after all his lessons and encouragement, I managed to pull up my grade to a 7. Another thing I appreciate about Ken Yi is how open and heartwarming he is. I genuinely looked forward to going to every lesson (even the extra ones because I wasn't doing well) because I knew I would have a fun time as well as improve my knowledge and understanding. He makes every lesson an engaging and insightful one and never fails to create a safe and cohesive space for his students to study in.
