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!

Desmond played an imperative role in improving my aptitude in Chemistry, and my methods for studying. From an initial 2 in HL IB Chemistry, Desmond helped me recognise my weaknesses with targeted guidance to boost my grade to a final 7. Now, I am studying medicine in Sydney, armed with the chemistry knowledge and studying tips provided by Desmond. Desmond is a tough cookie who tailors explanations to students, and that is the most outstanding trait that separates him from other tutors. Initially, I was intimidated by chemistry (Desmond considered it a phobia). Now, I can confidently say that it has become one of my best subjects.

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!!!

‘Lukewarm', would in a word, be how I’d describe my initial attitude towards chemistry. I neither detested it, nor particularly enjoyed it —it was just a necessity. With this tepid attitude, I managed 5s, 6s and the occasional 7 with just my trusty Marshall Cavendish. Not horrible grades, no. However, I felt a certain un-sustainability in my then method, as though there were gaping holes in my knowledge that I’d somehow managed to skirt around in every single test I took in school. Desmond solved this problem for me.

At Ace Brainery, Desmond, quite brutally (but with all the love in the world), dissected my prior knowledge of chemistry, identifying the aforementioned gaps in knowledge I wasn’t able to find myself. Over the course of almost 2 years, my initially lamentable chemistry foundation was fortified ten-fold, clearing any doubts I had previously harbored about most chemistry topics. This strong foundation brought my lukewarm attitude to a boil. The links between each topic gradually became clearer and clearer, as though each class came with a guaranteed epiphany. I not only enjoyed Desmond’s chill (like super chill) and effective classes, but also chemistry itself. Naturally, my grades saw a steady rise and 7s in chemistry weren’t goals, but rather expectations.

I give this testimonial with no exaggeration whatsoever. Do yourself a favor and join Ace Brainery.
