About Me:

I’m a doctor in chemistry, and I’ve got just the right prescription to help you ace your exams! Whether you're mixing up formulas or trying to make sense of tricky concepts, I’ll break things down with clarity, a dash of humour, and just the right dose of motivation. Learning science doesn’t have to be a pain—it can actually be a blast!

My students describe me as:

My students say I’m great at breaking down tough chemistry concepts and sharing little tricks that make things easier to understand. I like to ask extra questions to get them thinking more deeply and help them really get the big picture. Lessons with me are fun, relaxed, and full of good vibes—I try to keep things engaging and make learning feel a lot less stressful.

What our students say

"Under Dr Ryan’s guidance, I gradually learnt how to structure my responses accurately and use the right chemistry concepts with confidence. Dr Ryan is a very dedicated and passionate teacher. His lessons made complex concepts easy to understand, especially with the clear explanations and carefully crafted concept maps he created for us. Over time, I not only improved in the subject but also began to genuinely enjoy learning Chemistry. The A-Level question predictions and the additional double lessons leading up to the examinations were extremely helpful. They strengthened my understanding, boosted my confidence, and made me feel much less anxious when sitting for the actual papers. I’m truly grateful to Dr Ryan for his constant guidance and support. He constantly checked in on us individually and responded to any doubts promptly, which made a huge difference in my chemistry learning journey!"

- Florence Low, S to A, Class of 2025

"The double lessons helped me the most because they allowed me to get instant feedback and identify the gaps in my learning, so my understanding became stronger. During class, the materials and lesson flow were easy to follow and understand, and I was able to grasp the concepts clearly even before the school curriculum covered them. With a stronger foundation, my results continued to improve a lot. :)"

- Grace, Grade A, Class of 2025

"Zenith has really helped me by providing holiday crash courses and specific paper reviews! Their summary sheets proved really useful in the days before the paper, which I was super grateful for! I used to struggle a lot with answering chemistry questions, especially in Paper 2 and Paper 3. But, the summary sheets provided by Dr Ryan really helped me understand the concepts and improve my results!"

- Cady Lim, E to B, Class of 2025

"The double lessons were helpful because there was immediate feedback given, so I was able to improve on my weak points on the spot, which helped me better retain the information. At first, I struggled with understanding the concepts being taught. The lessons helped break the content into bite-sized pieces, making it easier to digest what was being taught. This helped me answer more questions correctly and quickly over time."

- Laura, Grade A, Class of 2025

"I struggled with the first few chapters of Chemistry in J1 and found it difficult to remember the key points to write in my answers. After attending the lessons, I was able to understand the concepts more quickly, and they stayed in my memory for longer. As a result, my results became more consistent."

- Nadea, Grade B, Class of 2025

"The dry lab sessions, A Level question predictions, concise summary sheets, and consults were all incredibly helpful. Since the start of JC, Chemistry was the subject I thought I would do poorly in due to a weak foundation from secondary school. However, Dr Ryan has always been passionate about imparting his Chemistry knowledge and exam tips to his students. I truly enjoyed learning Chemistry through his lessons, as he provides additional challenging questions to test our skills and concise mind maps that make revision much easier. I’m very grateful for his guidance, which helped me secure an A."

- Chelsea, Grade A, Class of 2025

"My experience in Chemistry class with Dr Ryan was amazing! We were always checked up on and the lessons were so engaging that I never found myself struggling to grasp concepts or lagging behind! Everything was always planned and an extremely concise manner and it helped me bridge gaps in my learning really efficiently. Before coming into Zenith, I struggled with a wide variety of concepts which were always in my head, yet not very solidified. Zenith's lesson plans are designed in a way that naturally helps to solidify key principles and ideas during the lesson itself and that was truly the key driving factor as to what helped me improve my Chemistry within quite a short runway! Dr Ryan also arranged extra remedial slots with my friend and I for additional consults and questions which was genuinely eye-opening especially with the way he explained complex so simply to us by breaking them down and ensuring we understood them and weren't blindly taking in information. My time with Dr Ryan, although short, was extremely efficient and splendid and I am so grateful for all his guidance, his patience and the sheer amount of knowledge he brings to our lessons as he shares fun facts that help deepen our understanding on Chemistry as a whole. Thank you so very much Dr Ryan!"
