Bryan Peh, ACSI

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.

Desmond is the most dedicated tutor I've met in all my years of schooling. Since I’ve met him, he has far exceeded the role of a tutor and has filled the role of a mentor throughout my A levels journey. His commitment to nurturing his students’ academic growth shows clearly in his work ethic. Desmond never took more than a day to patiently answer my slew of panicked questions. Before I joined Ace Brainery, I had barely been scraping through my school examinations and often considered myself lucky when I passed. I found that my effort rarely translated to results because my study method had been extremely unfocused. Desmond was able to streamline my study method to increase my efficiency and I saw my results improve exponentially. During CT2s, I managed to scrape an S grade. In the short period of 2-3 months between CT2 and prelims, I managed to improve to a C grade. In the month between prelims and A levels, I managed to secure an A grade. The trait that made Desmond an exceptional mentor was the fact that he never gave up on any of his students - he genuinely believed that hard work would pay off. Although some may consider his efforts harsh, they were definitely effective. If he hadn’t been as strict as he was, I almost definitely would not have done as well. Under Desmond, anyone who is willing to put in their effort will go a long long way, just like I did. Thank you Desmond!
