Hear From Our Past Students


Ashley Chua

Before Mr Joseph’s lessons, I have been getting Bs for chemistry. I disliked chemistry as the concepts were hard to understand. However, after joining his lessons, I found that I could understand the concepts easier. His lessons are fun and engaging! He always makes sure that I fully understand the concepts before moving on to the next chapter. He always gives me extra practice to give me more exposure to different types of questions to help me familiarise myself with them. This definitely helped me in my preparations for o levels as after attending his lessons, I scored a A2 for chemistry.

I joined about a year before O levels began with failing or borderline passing grades. After all Mr Ang’s help, I managed to get B4. He was always kind enough to answer whatever questions I had and was patient enough to go through them until I understood. Classes were always very enjoyable and actually helpful unlike some other places that throw endless practices at students expecting them to get better on their own.

I joined Mr Ang in the 3/4 of Sec 3. Prior to joining I was getting E8 for every exam. He made sure that I understood every chemistry concept required, and even taught us ways to memorise important concepts for our examinations. Every lesson was enjoyable and always filled with laughter. In addition, Mr Ang is very approachable and whenever I face difficulties when revising I could always text Mr Ang to clarify. After 1 year of his guidance, I was able to achieve an A2 in my O levels. I really thank him 😉

Having gone through Joseph chemistry and physics lessons these past two years I have learnt so much from him. Before joining his class my results for chemistry and physics were B4 and C5 respectively but after his lessons I managed to get A2 for both subjects. His lesson materials also are very useful and have helped me look at the topic from a different perspective than what my school is teaching. I definitely would recommend his lessons as they are really an eye opener that would help you broaden your view on the subject.

I was initially scoring between F9 and C5 to B4 and couldn’t get my grades high. Mr Joseph taught me the right method to study for chemistry and physics(combined) and encouraged me to put in the effort to work harder. Over time, things got easier, and for my O levels, I got an A1 for combined phys and chem. If your looking for a teacher that is persistent(in the good way) and thinks of the best ways to teach you despite your difficulties in learning, you got Mr Joseph.

Joseph is very dedicated teacher which will go out of him way to help us understand concepts and solve questions. Be it schoolwork or the questions given to us in the materials, Joseph will not hesitate to answer my questions I have and to clarify any of my doubts. Thank you all for your dedication and hard work especially during the A level period!

Mr Joseph was extremely helpful with his tutoring. The lessons were enjoyable and very concise in teaching exactly what each Chemistry and Physics chapter was about. I began Secondary 3 with borderline passes for both Chemistry and Physics but through Mr Joseph’s guidance, I eventually graduated with A1s for both of the subjects. Last but not least, Mr Joseph also exemplifies his love of work by always being available to answer any doubts and queries even in the middle of the night. Thank you Mr Joseph.

I joined AO Studies towards the end of secondary 3. At that time, my phy and chem were barely passing and I was beginning to lose interest in them. However, the lessons were engaging and I was able to better understand the topics. I was shocked that I managed to improve from C6 in sec 3 to A1 for both my Physics and Chem in the 'O's.

I joined AO studies at middle of Secondary 3 after failing my Chemistry with only 25/100 (F9). After joining the Tuition centre for only 2-3 months, i managed to pass my Chemistry paper for the 1st time.

My physics tuition teacher Joseph have really helped me in more ways than one. I loved his class from the moment I started attending it- and I've learnt so much from him too; I have my A1 in O Level Physics to attest to that.

Mr Joseph has taught me chem and physics since sec 3 to sec 4. Through the lessons, he uses really visual, interactive, interesting ways to teach his students that really makes chem and physics interesting. It's no longer something read from a book but made into something with life and something i really enjoy learning.

Despite constantly not doing well in school exams for physics, Joseph didnt give up, and gave extra attention to if i needed help in the questions we were doing in class. He was always willing to stay back after class to attend to my questions if i had any.

Why Take O Level Chemistry Tuition in Singapore?


 

In Singapore, O Level Chemistry is a subject that builds on earlier topics, with small knowledge gaps often snowballing into bigger learning challenges. As students progress through their upper secondary years, many also struggle with the heavy content load, abstract Chemistry concepts, and weak exam answering techniques

Our Proven Approach to O Level Chemistry Exam Success

We believe that academic success is built on a student-centric teaching approach, targeted practice, and consistent support. Over the last decade, we developed a unique, proven methodology that includes topical re-teaching, tailored learning plans, and clear answering techniques, helping hundreds of students excel in their GCE O Level exams. 

Beyond lessons, our students will also gain access to a wealth of Chemistry learning resources on our e-learning platform, including practice papers, tutorials, and targeted drills. We have also prepared a conducive study area for students to use at any time, with free-flowing snacks and drinks to keep them energised while they study. 

Supporting Students Through the SEC Transition

With Singapore’s transition towards the Cambridge Secondary Education Certificate (SEC) under Full Subject-Based Banding (Full SBB), students are expected to adapt to evolving assessment styles that place greater emphasis on conceptual understanding and real-world application in Chemistry. As a result, building a strong conceptual foundation has become increasingly important for students preparing for future SEC examinations. This is where SEC Chemistry tuition can provide structured support to help students strengthen their understanding and adapt to the new G3 Chemistry assessment framework.
