kind words from past students

“Hendra is a very friendly and patient Chemisty tutor who would explain the difficult concepts to me clearly when I am in doubt. Initially, chemistry appeared to be very daunting as it was very different from what I had studied before in the past. Furthermore, the fast-paced lectures in school and the hectic JC lifestyle made it even more difficult for me to keep up with the subject. However, upon joining Hendra’s lessons, chemistry became a much easier subject. He was able to break down the difficult concepts which makes it easier for students to understand. Hendra is also very helpful and would answer my questions outside of lesson through whatsapp. Thanks to him, I was able to consistently score A for both my school exams and the A levels.”

Achieved A for A-level Chemistry

“I’ve always thought of Chemistry as a complex subject especially when sec 4 topics came around. Mr. Hendra has helped me not only understand the subject but master the answering techniques required to obtain a distinction. His material is not only well compiled and organised but helps immensely with revision :”)”

Achieved A2 for O-level Chemistry

“Hendra is a kind and patient chemistry tutor that has helped me made huge improvements in my chemistry grades. He is knowledgeable and never fails to clear my doubts. His explanations are also clear and concise to understand. The resources that he provides for example, worksheets, have allowed me to practice and work on my doubts. I had only joined his tuition a few months prior to the O levels examination, but I was well prepared to face the chemistry exam with his guidance.“

“Hendra is a very knowledgeable and patient tutor. He explains in a way that is easy to understand and clear, and this has helped me see vast improvement in my chemistry grades. He never fails to answer my questions, and under his guidance, I managed to develop a desire to learn more of the subject. I used to have difficulty understanding and learning chemistry, but found this to be a lot easier after joining his classes. Thanks to him, I was able to score consistently good grades in my both internal exams and A levels.”
