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!

When I first came to Ace Brainery in the middle of Y5, I had just taken my first exam and got 59%, a solid 5 points, one of the lowest in my class. I couldn't even understand the difference between an atom and an ion, let alone comprehend anything else I was learning in school. Desmond was not only extremely clear in explaining all the concepts to me, but he has a unique talent of making the most difficult concepts simple to understand - something I had never encountered in Chemistry before stepping into Ace for tuition. After gaining a new perspective about Chemistry, I began to love the subject so much more. Instead of feeling daunted by it, I was inspired to work harder for the subject. Not only did Chemistry become my favourite subject by the time I graduated from IB, but it also became my best subject. I managed to get 89% for IB which is a 7. My decision to join Ace was honestly one of the best decisions I made during my IB journey and I definitely highly recommend Desmond to anyone who is seeking help for Chemistry!

Before I joined Ace Brainery in IB1, my Chemistry results were barely satisfactory. However, under Desmond's guidance, I was able to get a grasp on the important concepts, which allowed my interest in chemistry to quickly grow. Desmond is a creative, dedicated and passionate Chemistry teacher with knowledge unparalleled to any other tutors I have encountered. He motivates all his students, and really brings out their potential. Because of Desmond, I was able to jump from a grade 5 to grade 7 in my final IB examination. If one is willing to put in the necessary effort on an individual level, together through attending Desmond's weekly lessons, I can guarantee that any student will get a high distinction in Chemistry under his tutelage.

At the start of IB2, I was struggling a lot with Chemistry so I was desperately looking for help. It got so bad to the point that I was at the bottom of the class for my mid-terms, which was 5 months before the IB exams proper. This was when Desmond sat me down, and helped me to find my passion in Chemistry. He made complex concepts easy to understand, with the aid of physical chemistry models and also his funny acronyms. Under his guidance, my grade went from a grade 2 to grade 7 for IB. I am so thankful that I found such a great tutor whom really made learning so much more fun! Today, I am learning Chemistry in university and Chemistry has become part of my everyday life! Thank you so much Desmond!!!

I joined Ace Brainery at the start of Year 5 with a relatively poor understanding of Chemistry. Desmond was extremely patient in his teaching with a strong emphasis on really the most basic of the concepts. He would often go out of his way such as staying back with me after class, to clarify any doubts that I may have. Desmond would also take the time to constantly reply to my queries over WhatsApp, which I really appreciate. Through my 2 years at Ace Brainery, I referred 4 of my friends whose only regret was not joining earlier. Desmond is the best tuition teacher that I have ever met. He really is a teacher that goes above and beyond. I managed to attain a grade 7 for HL Chemistry during the IBDP examinations. I highly recommend that you enroll in Ace Brainery. You won’t be disappointed!

My experience with Ace Brainery has been one that has equipped me with not only a solid understanding of Chemistry, but with a lasting interest for the subject. I can walk into class with many doubts on certain topics, and practically walk out with all my doubts cleared. I think the thing that I am most thankful for in my classes with Desmond was that classes were always fun. Zero regrets since signing up!!!
