Before I joined Ace Brainery, Chemistry was one of those subjects that made me feel like I could not reach my fullest potential regardless of how much I studied. Desmond constantly encouraged us to ask him questions, even after lessons, and he was extremely helpful. He explained abstract concepts into content that I could easily grasp and understand.

Lessons with Desmond are never mundane. He always challenges us to think beyond what is given in the school notes. His teaching most definitely strengthened my foundation in the subject. Together with the invaluable study tips he taught us, I was able to perform to my full potential during the IB exam.

Desmond doesn’t just fulfil the bare minimum as a teacher but goes the extra mile. He has helped me gain much confidence in Chemistry, even in topics that I used to be the worst in. He always motivated me to study harder and keep doing better. His dedication and passion are hard to find elsewhere.

I have recommended several of my friends to join Ace Brainery and we are all immensely grateful for Desmond’s help and hard work!

I first joined Ace Brainery at the start of Year 6, after barely passing my Year 5 promotional exams. Within just a few lessons, I could see an improvement in my Chemistry proficiency. Mr Desmond always made lessons interesting and easy to understand, allowing me to be able to grasp concepts fast. Furthermore, Mr Desmond would even stay back after lessons to answer my questions, even encouraging us to text him outside of lesson time to ask questions. Even though I had multiple questions, he would take the time to answer each question slowly and explained them excellently. Due to Mr Desmond’s help, I managed to secure a 7 for Chemistry, which was something I never thought was possible. Thank you Mr Desmond!

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!

I joined Ace Brainery at the end of year 5. I had been struggling to cope with both my CCA and my academics and ended up falling  rather behind my peers in chemistry. I had been looking around for tuitions, and people around me have been encouraging me to try out Ace Brainery. And I must say that it was the right decision to give them a shot! Desmond has a unique way of teaching that really piqued my interest in Chemistry. The best part is that he cares for each and every one of his students. He bothers to go out of his way to help me. There were numerous times when he answered my question late into the night just to make sure that I understood the content that he has taught. I really gained so much confidence in the subject and its because of him that I managed to pull my grades from a low 5 to an eventual 7. So if anyone is struggling with Chemistry, I will definitely recommend Ace Brainery to them!!!

I joined Ace Brainery after my secondary 4 mid year Chemistry exam which I failed. I started 1 on 1 lessons with Wilson who was extremely encouraging even though I really struggled to grasp the concepts initially. After only 2 months of lessons with him, my Chemistry grade jumped from a 3 to a 6.

In IB, I continued lessons at Ace Brainery under Desmond. His teaching was extremely helpful in bridging the gap between secondary and IB Chemistry, and keeping us on top of the curriculum for the entire of the 2 years. He taught us effective ways to learn the content, as well as efficient ways to tackle assessments - both of which played a large role in seeing me through my IB exams. I’m especially grateful that Desmond was always considerate of our busy schedules and gave us the bare minimum when it came to homework, and also for his patience in answering our many questions. He really made sure that we understood what we were learning and even took the time to schedule revision classes for us before our exams.

Thank you very much to both Wilson and Desmond for making Chemistry so enjoyable!

Chemistry has always been one of my weaker subjects in secondary school, but joining Ace Brainery has helped to greatly improve my understanding of the concepts. Desmond makes the lessons easy to follow and he has helped me to develop a good foundation in Chemistry, which definitely goes a long way when we have to learn the more complicated topics. His friendliness and patience creates an incredibly conducive and fun learning environment, where one is able to ask questions freely. He also gives really useful tips for exams that make exams a lot less stressful! After joining Ace, I happened to have a lot more time to focus on my other IB subjects too. Desmond is a really great teacher and I would definitely recommend Ace to anyone who finds Chemistry challenging!!!

Before joining Ace Brainery, Chemistry was my most feared subject as I found it very challenging to grasp the concepts. I am so thankful for Desmond because he miraculously makes these difficult concepts easy to understand and dramatically lowered the steep learning curve for me. Desmond’s notes are so clear that I always rely on my Ace Brainery notes, instead of the school’s notes. Desmond is also able to accurately spot questions, which is so helpful nearer to the examinations. Before I joined Ace Brainery, I was always behind in class and could not keep up with my peers. It is amazing that after attending the Ace Brainery crash courses and lessons, I was brought up to speed and could even excel in the subject. Desmond is not only an effective teacher, but also a caring one. He shows genuine concern for the progress of each and every student and I am so thankful for the huge amounts of effort that he puts in. I would really recommend Ace Brainery to any student taking Chemistry. Without Desmond, it would have been impossible to get a 7 for IB Chemistry! Thank you Desmond!!!

As someone who was caught up with many commitments in school, I found myself falling behind in terms of content, especially for HL Chemistry. Luckily for me, a friend of mine referred me to Desmond. He really helped me to catch up on the Chemistry content in school, and to even learn ahead of the school syllabus eventually. Although Desmond seems a bit intimidating at the start, his teaching style is engaging, interactive and fun, which really helped me to focus during the lessons. He also provides many tips and tricks that helped me to remember certain key concepts during tests and exams. Outside of teaching, Desmond is also a down to earth, caring and understanding individual who you can definitely confide in when you are facing difficulties. Ace Brainery really helped to push me towards a 7 for HL Chem, and I would definitely recommend Ace to my juniors!
