Nicole Leong, ACSI

Since secondary school, Chemistry was never a subject that I could grasp. All the information seemed abstract and I never really scored well in examinations even if I studied. I continued to struggle with Chemistry during IB, and when I got a 5 during my Year 5 promo exams, I decided to look for help, especially as I hoped to pursue medicine in university. Joining Mr Desmond’s class was probably one of my wisest decisions. He is always engaging in class, and also encourages us to ask questions. He clarified every single doubt I had, frequently sharing exam tips on how to study effectively, and helping to draw links between various topics. I never expected my understanding for the subject to be able to improve so much in the span of less than a year. I even started to enjoy learning Chemistry, and eventually managed to get a 7 for IB. I’m truly grateful for all his support and am genuinely blessed to have had him as my teacher.

Being taught by Desmond for 2 years definitely developed my love for Chemistry, making it my favourite and strongest subject. Desmond is one of the most hardworking and dedicated teachers I have met. I really appreciated everything from the tricky questions he asked us in class, to his useful exam tips and strategies, and the constant help he gave students both during and after class. What makes Desmond a really special tutor is how much he cares for each and every one of his students, catering to their individual needs. He always encouraged us to send him questions via WhatsApp, and would answer them at any hour. I remember sending 10-15 questions in a row (not just once), yet Desmond would take the time to explain everything in voice recordings until I understood. Moreover, he sometimes praised and encouraged me during class, and that motivated me to work harder and improve faster. Desmond’s guidance has allowed me to consistently score 90 and above in all my Year 6 examinations, with a final score of 93 for my IB HL Chemistry exam, and I could not be more grateful. I’ve recommended Desmond to many of my friends, as I can say for sure that he will help anyone excel in Chemistry. Thank you Desmond!

After my O Levels with Wilson, I continued my lessons at Ace Brainery under Desmond. The jump from O Levels to IB Chemistry was indeed quite big, but Desmond made difficult concepts easy for me to digest. He caters to students of different learning paces in his classes, taking the time to ensure everyone follows the class. His lessons are carefully planned in order to cover the syllabus in time for our promos, prelims, etc.  Beyond Chemistry content, he prepares his students with exam tips and help outside of class time, speedily answering any questions over WhatsApp. Desmond is dependable and dedicated to his students, going the extra mile for us all. Making the effort to comfort us in stressful times, he truly brings out the potential in his students. Thank you Desmond for the constant support!

Honest and kind, Desmond works extremely hard to ensure students across all standards achieve their fullest potential. As the third student in my family who has gone to Ace Brainery for IB Chemistry, I understood why my sisters always spoke well of him. It was because of how easily he simplified difficult concepts, understood each student's weak points, and going the extra mile to help us during and after class. With his consistent guidance and teaching experience, my sisters and I all attained a 7 for IB Chemistry. Thank you Desmond for empowering your students in the ways that you have!

As a competitive swimmer, I had to travel often for overseas training camps and competitions. It was not a surprise that I was pretty behind schedule in my final IB final year due to many lessons missed in class and honestly, I had a lot to catch up for my HL Chemistry. I was very fortunate that Desmond was able to help me work out a schedule to coach me. He really helped me to understand the subject matter within a short span of time. He somehow has the ability to simplify and condense complicated concepts into very effective lessons. Not only is Desmond patient, but he is also very dedicated to all his students. I am very grateful for his guidance. Thank you Desmond!
