I knew that I had to go get some help when I scored a big fat 3 for Chemistry at the start of the second year of IB. I am so thankful that I discovered Desmond's Chemistry tuition.

1. Super focused

Desmond has this uncanny ability of compressing pretty much the ENTIRE big chapter (e.g. Organic Chem) into just a few sessions. Plus he does not blindly go through the content. He always highlights the parts thats important for the exams and tells us what to memorise and what not to. That’s literally spoon feeding, which saves me days of headache!

I am also very impressed by how Desmond managed to go through the entire of Chemical Bonding in just 3 hours. I joined Desmond's lessons pretty late but the additional 1 to 1 adhoc lessons helped me to catch up with the class.

2. Structured

Desmond knows exactly what to go through every lesson so that he finishes the syllabus in time and then proceeds to go through the past year exam questions. When it comes to knowing what one is doing, Desmond is the man to trust. He also prepares revision questions before lessons so that I get reminded about the stuff I previously learnt.

3. Nice

Desmond is one kind soul. He literally doesn't mind staying back after every lesson and answering all the questions I send to him via WhatsApp.

Last year, I pretty much spammed Desmond with A LOT of questions via text (especially during the exam season), causing his phone to vibrate pretty much every few minutes. Nevertheless, he answered all of them properly and I'm super grateful for it.

So yeah, thank you Desmond! I couldn't have scored 7 for HL chem without you!

When I first joined Desmond’s HL Chemistry class, I was extremely lost in school and had not much idea as to even approach basic Chemistry questions. I was scoring grade 4s and 5s for Chemistry in Year 6, and I was really worried because no matter how I studied, I just could not understand the subject matter. However, Desmond explained Chemistry concepts very well and also effectively planned his lessons so that we managed to cover all required revision before our actual IB exams. Desmond’s confidence in his teaching  reassured me, because I knew that I would be able to get 7 in Chemistry as long as I followed what Desmond told me to do. Sincerely, trust in Desmond and you will get your 7!

Since my secondary school days, my Chemistry has been very weak cause I often missed school due to my involvement in competitive tennis. Hence, I really struggled in my first year of IB for HL Chemistry, and just managed to scrape 5 points for the finals. It was then when my friends recommended me to join Ace Brainery. I thoroughly enjoyed my lessons with Mr Desmond as they were interactive and productive. He is able to break down complex concepts into tiny digestible bits, allowing me to grasp the concepts much better. Mr Desmond not only does work with us during the weekly scheduled sessions, but also helps his students via whatsapp even in the late hours of the night (he has replied to my chem queries numerous times after midnight). His care and dedication has really helped me improve my Chemistry. I definitely would not have been able to achieve my final Chemistry results without his help! I am extremely grateful for Mr. Desmond. Ace Brainery is definitely the way to go :)

 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!

Joy Sim, ACSI

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!
