Before I started Chemistry lessons at Ace Brainery, I found it really difficult to understand the subject. It was really tough to keep up with my school’s lecture pace, and I was often clueless during my school’s tutorials. Through Desmond’s constant guidance and comprehensive notes, I was able to grasp the main concepts much more easily. He would also clear my doubts outside of tuition time every single time without fail, and even take the effort to explain them in great detail. Nearing our A levels, he also provides crash courses for us to attend. Each lesson covers a different topic, thus we were able to brush up on specific topics that we were weaker in, which made it very helpful. Desmond is a very dedicated teacher who genuinely cares a lot about his students, and I would definitely recommend everyone to join Ace Brainery. Had I not attended Ace Brainery, I definitely would not have been able to secure my A in H2 Chemistry for the A levels.

I joined Ace Brainery in J1 after my terrible mid-term exam results. Before this, I never truly understood the Chemistry concepts taught in school and always struggled to understand the logic. However, with Desmond's help, my grades got quickly pulled up from an E to a C for the promotional exams. Desmond simplified Chemistry by making the concepts easy to understand and also linking them to one another. I began to much more confident in Chemistry, and I could not believe that I actually ended up loving the subject. I would definitely recommend Ace Brainery to anyone struggling with Chemistry! I wouldn't have done it without Desmond's help. It was truly an exciting journey here at Ace Brainery. Thank you Desmond!

I started attending Desmond's Chemistry lessons mid-way through JC2, as he was very highly recommended. Before that, I didn’t have much interest in the subject and merely see it as a requirement. Desmond’s classes were super engaging and he kept everyone on their toes throughout the entire duration of his lessons. The questions he posed in class were good refreshers (although embarrassing at times if I answered wrongly, haha). He made me realise how important the basics were even at the JC level. Desmond somehow has enough time to mark all the papers he gives us for revision and answer every one of our questions outside of class, which really shows his dedication to helping his students improve. After a while, I started to become interested in Chemistry, and I even looked forward to the weekly lessons! Never once did I come out of class having not gained/learned something. Despite being his student for a short while, Desmond’s lessons and teaching style really impressed me (and made me laugh). Thank you for the enjoyable semester, Desmond!

My seniors introduced Ace Brainery to me during the mid of my JC1 when I was struggling with Chemistry. Within 2 months, my Chemistry grades improved from a D to B for my Mid Year Examinations. Desmond makes learning Chemistry very interesting, and his lessons also motivate me to do well. Furthermore, his interactive teaching style allows for me to actively participate in class and deepen my understanding in the subject matter. He also makes the memorising of content happen more easily through questions in class and also through his own mnemonics. His lessons are also very tailored and applicable to my school exams, and eventually the A Levels. One thing that I really appreciate about Desmond is his availability! Whenever I face problems while attempting additional questions, I feel very comfortable with texting him because I know that he will answer my queries even though it is considered as extra work for him. Desmond is a very passionate and motivational tutor who  really believes in all of us. He is really a morale booster. Thank you so much!

I joined Ace Brainery a few months before my GCE ‘A’ Levels. I had difficulties tackling basic questions that would have prevented me from even getting a B in my school exams. Desmond was easily able to identify issues that JC Chem students frequently have, and shared it with his students. He condensed the topics into easily understandable concepts by breaking them down and also introduced his own acronyms, revealed tricks to knowing what the question is asking for to make sure that we would be able to complete the paper in time with accuracy and precision. He did not only teach us to work hard, but also to work smart. I could notice myself improve significantly in the subject compared to the time before I joined Ace Brainery. Lessons were simple but effective. We had to jot down notes and answers in class, and were also able to ask questions in person and on WhatsApp. All these really helped to consolidate my knowledge in Chemistry, and piqued my interest in the subject, pushing my grades from a D in my J2 mid year exams to an eventual A in the A Level exams. Desmond is very understanding of the tight schedule students experience, and gives just the right amount of pressure and work to us. He also encourages and motivates his students. Interestingly, I was eventually no longer daunted by the subject, and in fact even started to like and enjoy it. I would definitely recommend Ace Brainery to my friends and juniors as it is a conducive environment to learn. Thank you, Desmond!

The only thing holding me back from having tuition was cost and I was also pretty skeptical of this sorcery Desmond uses which can even push one from a U to an A. But joining Ace Brainery was something I’m so glad I eventually did nearing As because not only does Desmond makes Chem fuss-free and straightforward, his confidence in his own teaching made me very relieved as well. He also helped financially which is definitely a plus point I’m very grateful for. If you’re looking for a trusty Chem tutor, I’m positive Ace Brainery is your best bet out there.

Ace Brainery is a brilliant chemistry tuition centre, not only because of the knowledge it imparts, but also because of the teacher who makes the lessons interesting and engaging for everyone. Through Ace Brainery, I managed to learn much more about chemistry than I thought I ever would. Not only did Desmond help me improve my chemistry skills, he also inculcated my love for the subject, which not just any teacher is able to do. From struggling with Chem till getting the eventual A for my H2 Chem at A Levels, Desmond was there all the way for me, not only academically, but he also looked after my welfare, stepping out of his role as a tuition teacher to put in effort to ensure that I was doing well in other areas of my life too. I am especially grateful for the financial aid he provided for me, as without it, I don't think I could have progressed so far too. Something else that deserves special mention is that my percentile in NYJC doubled from about 50 to 95 in merely a few months with him.

My entire perspective of chemistry, tremendous improvement in results and a gradual love for it is all credited to Desmond! Without him, I definitely would never have achieved the same outcome. Back before I knew of Ace Brainery, I disliked Chemistry as I was consistently bad at it. Lectures and homework were all dreadful and I didn't know what was going on most of the time in J2. However, after I started attending lessons in June, that's when things changed. Desmond's unique style of teaching was good as he recapped whatever I misunderstood. His explanations were concise and rich in content, often covering what was tested in exams. Each time he would ask questions to challenge our thinking and his scolding really played a huge role in making me always prepared for any questions to come. Apart from his teaching style, he is also very approachable and friendly, always ready to reply to any queries I have. He genuinely cares for his students' welfare and would ask how I am doing from time to time. He is not just an amazing teacher, but also an amazing friend! Because of him, I improved from 31.0 (BT1- U) to 90.1 (PRELIM- B) percentile within just 5 months! Without Ace Brainery I would definitely not have come this far!

Ace Brainery is the best tuition centre around for someone that is looking for a fun and lively study environment, but yet is able to learn alot! In all my lessons with Desmond, I never really dreaded any and always looked forward to the next class cause Desmond makes his lessons really fun and interesting. Chem didn't feel like chem with him... He really taught it in a way that made it interesting and I really promise he's super experienced and knowledgeable, about not just the Chemistry syllabus but also what the schools expect and teach.

He has helped boost a lot of my friends from a U grade to an A and none of my friends whom I have recommended regret joining him! He's a great tutor who's fun-loving, chill and teaches very well. Your lessons will never be boring! You'll never regret joining him and thanks to him and his teaching I got an A in the A levels!!!

A man who stands by a principle of moral righteousness, what struck me the most was his willingness to accept students regardless of their financial background and compromising for those who may not be able to afford the full tuition fees. And that’s just scratching the surface. His fair treatment of every student no matter their level of chemistry depicts his aptitude for teaching, and he connects with students not only on a teaching level, but on a personal level as well. Being well versed with the chemistry syllabus is an understatement, for Desmond is someone who lives and breathes chemistry. His dedication to the subject and flair for teaching is evident in his teaching style, for he is able to filter out what’s important and what’s not, and come up with learning methods catered to the needs of his students. “The mediocre teacher tells. The good teacher explains. The superior teacher demonstrates. The great teacher inspires.” The depth of a teacher is not by how much he teaches, but how much he is able to inspire. Desmond, thanks for being a teacher that inspires.

Desmond is a kind and caring teacher who’s committed to his students. I thoroughly enjoyed his classes and am grateful for all that he’s taught me! After going for his classes, I understood chemistry much better and developed a better appreciation for the subject. I would highly recommend Ace Brainery as a productive and conducive environment to learn.

Before attending classes at Ace Brainery, Chemistry was a subject which I really detested. I had zero interest in the subject. Ever since I started lessons with Wilson in Secondary 4, my attitude towards the subject changed for the better. Not only was he clear with his explanations, he was also able to inject fun into the subject through the occasional jokes. As much as it might sound less professional, I think that kind of style is really what makes the lessons more effective for most of the students. After I entered ACJC, I took H2 Chemistry and continued classes with Desmond. He was able to keep my Chemistry afloat for the entire year, whilst most of my friends struggled amidst the hectic JC curriculum. On top of all that, the tutors are very helpful and are willing to answer questions outside tuition time. From the perspective of the students, one can clearly see how they are interested in the welfare of each and every student.

To top it off, Bijay Naidu from ACJC (my elder brother) also took H2 Chemistry lessons with Desmond. He improved from 0.1 percentile at the end of JC1 to 84 percentile at the end of JC2, which is clearly the reason why my mum enrolled me with Ace Brainery.
