Chemistry was always one of the toughest subjects for me and I was never able to score well for it. But after joining Mr Toh's classes, I have so much more confidence in the subject and was eventually able to score a distinction in my final exams. Chemistry was a nightmare subject for me and I struggled tremendously for it. Not only did Mr Toh helped me understand the concepts easily, his constant encouragement was what kept me motivated to want to do well for the subject. I really enjoyed his classes which in turn made me enjoy the subject better. One thing that made him stand out from all other tutors is that he will never give up on any student even if we were on the verge of giving in. And that is something which we all appreciate and liked about him.

Before Ms Jes was my tutor, I was severely struggling with IP maths, barely even passing every exam. However, after she started helping me with my Maths, my grades increased exponentially with both my Advanced Math and Core Math scoring distinctions within a few months. Ms Jes definitely saved my grades and she even instill in me the joy of doing Mathematics. Her constant pushing and encouragement allow me to quickly adjust to be able to do many challenging questions, giving me the base required to excel in exams. I even received the most improved award in class for Maths! Her teaching methods has build so much confidence in me that I am now able to breeze through my IB Maths without any help from anyone.

I enrolled in Mr Alex's class in July of my Sec 3 year due to consistent E8s and F9s in my Chemistry test and exams. I used to dread the subject and have lost all motivation to do well for it. But after attending Mr Alex's classes, I could understand the concepts so much better. His classes are structured in a way that made learning enjoyable and easy, which helped me get interested in the subject. With his guidance, I managed to clinch an A1 during my Sec 3 EOY exams within a few months! Mr Alex is a very caring, supportive and dedicated tutor who will go out of his way to help a student do well. His lessons are engaging and his passion for the subject is evident in his teaching methods, which in turn act as an inspiration for all of us.

Before I joined Mr Alex's class, Chemistry was one of the toughest subjects as I never understood what it was about and neither did I have any interest in it. I never passed my Chemistry tests and exams during my Lower Secondary years as my foundation was extremely weak. However after the first few lessons, through Mr Alex's thorough explanation, I realised chemistry is actually not difficult and everything was made so much clearer to me which allowed my interest in chemistry to grow gradually. When I didn't understand certain questions even after several explanations, Mr Alex would always explain it to me in many different ways to make sure I understand it. And to my surprise I actually showed tremendous improvement for chemistry during my Sec 3 exams. Mr Alex will always be there if you need any help and is very patient with each and every student. Because of his continuous effort and clear explanations, I was able to ace my EOYs in Sec 4 and achieve an A1 in Chemistry!

Ms Jes is a very patient tutor who takes time to make sure that I fully understand every topic. Whenever I face difficulties in certain parts of a topic, she will use different ways and questions to help me understand them better. What I like about her way of teaching is that she will structure her questions such that they progressively advance to more challenging questions so that it enhances my level of thinking, which I find very beneficial. During examination periods, she painstakingly ensures that I am able to tackle the various common examination questions, allowing me to perform very well in Mathematics throughout secondary school.

Mr Alex has been my Chem tutor since Sec 2, and every lesson with him has always been interesting and allowed to me easily grasp Chemistry concepts quickly. Without Mr Alex, I would have never been able to take IB HL chemistry. Mr Alex is kind-hearted and devoted to teaching his students and will always take time to answer any of my queries about Chemistry and even about school life and university life. He has successfully made Chemistry one of my favourite subjects that I find joy in learning about and have an interest in furthering in during my university days. He is honestly a superb teacher and a great friend.

Before joining Mr Alex’s class, my chemistry grades had always been stagnant at B4. No matter how hard I tried, there seemed to be no improvement. After being taught by Mr Alex, I saw a significant improvement in my grades. Mr Alex has a clear way of teaching, and because of his experience, he is able to guide us well through the various questions over the years. I genuinely found chemistry to be easier, and more fun after attending his classes. In the end, I received an A1 for o level chemistry.
