Mr Goh has a very broad and thorough understanding of Mathematics concepts which he ensures is clearly passed on to his students. For me, this helped build a strong foundation which was further boosted by the ample amount of practice he provides. With his unique knowledge of little-used exam tips and strategies (such as GDC shortcuts, alternative solutions to problems, or quick ways to check answers), he helps his students find faster ways to solve problems which can be very helpful in saving time during exams.

Additionally, Mr Goh has a keen eye for detail and thorough knowledge of what examiners are looking for in a student's work. Along with his ability to connect the concepts he teaches across various topics and to real-world implications, he can definitely help students achieve a deeper understanding and appreciation for Math.

Mr. Clifford Goh tutored me in IB Mathematics Analysis & Approaches and is, by far, the best math teacher I've ever had. He took my math grade from a 4 to a 7. I joined him towards the end of my first IB year.

Being tutored online was foreign to me, leaving me skeptical about the whole concept and signing up with him. However, contrary to popular belief of online teaching being less effective than in person teaching, he still managed to effectively impart his rich math knowledge into me. When I joined him, he completely opened up my eyes and changed the way I viewed math as a subject.

Before, I used to accept formulas as they were taught to me, never questioning how they were derived or applied. This approach worked well for me in secondary school, taking O levels. When I entered IB, Mr. Goh helped me realize that this method of learning was not effective in higher levels of education.

Of course, there was a steep learning curve at the start, where I did not really understand many applications, proofs, "tricks," and ambiguous situations that he said were "important to know," reflected in my grade 4 result during the end-of-year promotional exams. However, these "tricks" eventually clicked, proving extremely useful in solving IB math questions, just as Mr. Goh said.

His teaching method, making me fully understand the formulas instead of memorizing them, was a refreshing change from my previous view of the subject, making me appreciate what I learned from him, which he called "real maths." He advocates for this way of learning because he himself frequently questioned the "why" and the "how," enabling him to have a deeper understanding of the subject than any teacher I've had without exaggeration.

One thing I truly admire about Mr. Goh is that he is not afraid to be hard on me. There have been many instances where he loses his patience because of my stubbornness or the number of careless mistakes I make, revealing his true passion for mathematics and teaching in general. I've talked to Mr. Goh many times after he lost his patience with me, and I've established that it is not personal, and I prefer it this way. In fact, I want to and am here in his class to learn from the best. This also lets me strike a perfect balance of fear and respect for Mr. Goh, whom I look up to.

Additionally, Mr. Goh’s teachings extend beyond the realm of mathematics. He occasionally tells me stories and teaches life skills and money management, cautions me about situations in university, and shares how he managed to land in the position he is in today - in his early 50s, semi-retired, teaching simply out of passion.

Initially, like many, I thought his fees were hefty. However, I believe that you truly have to experience one of these classes yourself to understand the verbal liquid gold he distills for you from decades of knowledge. You pay for what you get, and I'm sure to attain a 7, build a deep appreciation for the subject, and learn math in a new way where the benefits of this learning style can carry over into university. It is absolutely worth it.

If anyone reading this testimony is still contemplating signing up with Mr. Goh, I strongly advise you to sign up with him for a few sessions just to understand what I mean. If you end up staying with him for as long as I did, I'm sure in the following years you will be in the exact same position as me, writing an extremely passionate testimonial because it is the least I could do after what he has done for me.

Before going for Mr Goh’s lessons, I consistently had gotten a Grade 2-3 for the various tests and exams. After his committed tutelage, I have managed to attain a Grade 7 in the IB Math AA syllabus examination in a relatively short time frame.

Mr Goh, paced me to learn the topics with sufficient depth, while making the necessary connections with other topics.  He starts off with a simple idea, and builds on it to a complex idea so that you can truly appreciate the beauty behind every theory or formula.  Mathematics became less mundane and more fun to learn. Internal Assessment (IA) for mathematics is particularly daunting for many, as teachers in school typically provide skimpy feedback, owing to the time constraints and IB restrictions. Especially when I'm doing IA, he has provided very good ideas as well as consistent and detailed guidance, for after his years of experience as an IB teacher, he knows precisely what the examiners are looking for.  Since IA is a very important component of the grade, as it constitutes 20% of the final grade, Mr Goh has helped me secure a high grade in IA and I therefore would not have as much pressure to do extremely well for the final written examination.

Lastly, Mr Goh teaches you certain GDC savviness that are unknown to students and teachers to not only double check, but more importantly, obtain the answers in the fastest manner. Time is of the essence in Math AA syllabus examinations and these skills will be essential in maximising your grades.

Mr Goh is an exceptional educator with the ability to pinpoint and address specific gaps in his students' understanding. He possesses a strong grasp in the subject given his many years of teaching, which allows him to clearly teach his students his own incredible exam strategies and best methods to tackle trickier questions. Additionally, he has initiative and often attends courses about math and bothers to find out changes in its testing over the years, hence placing him ahead of regular school teachers in terms of understanding. Though I only had less than 4 months of time with him, he was miraculously able to push my Mathematics grade from 3 in CTs to 7 in IB examinations. I strongly recommend him to any student interested in truly appreciating the subject and eager to actually internalise how to approach it correctly.

My Maths IA was by far one of the most difficult tasks of my IB. But luckily , at the start of my IB Year 2, I started working on it with Mr Goh. Mr Goh gave me clear guidance throughout the process- this allowed me to transition through it smoothly. Additionally Mr Goh’s approach allowed me to gain a thorough understanding of my IA that later helped me when I was finally proofreading my IA before submitting it. Above all though, I think Mr Goh has truly improved my understanding of mathematics. The tips and tricks I gained from him really helped me finally achieve the level 7 for HL Maths. I truly would recommend him for anyone starting their maths ia and HL Maths students.

Mr Goh tutored me from the start of Year 5 up till my graduation in Year 6. I’m sure you would’ve read many reviews of brilliant students praising Sir’s amazing math intuition where he is able to seamlessly integrate concepts from different chapters and extend his teachings to real-life applications beyond the discipline of mathematics itself. I write my testimony (written autonomously – no strings attached) from the perspective of a student who was not naturally inclined towards Mathematics, but gradually fell in love with it after being taught by Mr Goh. Before I start, I just want to thank you (Sir) for your patient instruction for the last two years. It wasn’t easy being your student due to the numerous challenges and obstacles we had to overcome together, but I learnt a lot.

Initially, I studied math for its practicality, not completely because of my love for the subject. Nonetheless, as i had the fortune of meeting Sir, I was exposed to a syllabus that surpassed your average classroom content. Suddenly, math wasn’t so dry. Even as a student who was considered average in mathematics, I experienced several “wow” moments every session, even if I didn’t always understand his teachings at first. My Math Exploration (ME) in particular impressed me, and after all the confusing nights and hints left by Sir, I managed to come up with a report that I never knew I was capable of producing. Moreover, it was very different from what the rest of my peers had come up with.

Even if you are a student who studies math as a means to an end without the innate desire to understand further, I can guarantee you that Sir’s approach in ensuring academic excellence for your exams is strategic and foolproof. Whenever Sir teaches you to deal with a problem, he gives you two to three methods. After being with him for a while, he will also impart upon you some mathematical sense or GDC savviness that will help you to double check your answers.

Personally, I believe that the best part about being Sir’s student is that no matter how strong or weak you are, if you are willing to commit effort, he will really try his best to help you. He is about as communicative as you are with him, but also about as desperate (or passionate) as you get. Also, he’ll only ever get angry at you for laziness, but never for being slow. I think that there is no doubt, Sir’s fees are very expensive, which may put some people off. But at the end of the day I really felt the difference. Not just in mathematical ability, but also in conventional life wisdom. Given the chance to travel back in time, I would’ve definitely made the same decision of learning under Sir.

Grade 6 for HL Math

Mr Goh helped me pull my math grade from a U to an A in the span of 3 short months.

Throughout JC, I was always struggling with H2 math. No matter how I studied, I wasn't able to fully comprehend the concepts, and thus could not solve the questions at all. As a result, I failed all my test grades, from the smallest class quiz to the end-of-Year promotional exams. I had almost given up, and thought that since I lacked the natural aptitude for Math, there was no hope for me to improve my math results. However, under the urging of my mother, I decided to try out lessons with Mr Goh.

Even though I didn't have a lot of confidence in myself, Mr Goh made sure to remind me that I was capable of achieving good marks in math. This was vital in helping me in my A-level math journey, and really played an essential role in keeping me motivated for this subject. Mr Goh made learning a very enjoyable experience and under his guidance, I slowly started to comprehend the mathematical concepts which I previously found so difficult. He had tips and tricks that were not taught in school, and was able to guide me to approach question solving in novel ways that were incredibly intuitive. He also pushed me to work harder and harder for math, ensuring that I did my due diligence in the form of practice questions and papers. Ultimately, during the A level papers, I managed to answer every single question, something that I had failed to do throughout my JC experience.

For A levels, I scored an A for math, the first A in the past two years, and I can say with 100% confidence that I owe it to Mr Goh. Thank you!

With Mr Goh’s help, I managed to improve by leaps and bounds in Maths. Although I only joined after my mid-year exams in Year 6, which was considerably later than most of his students, I was able to grasp content that I could not understand for months under Sir’s patient teaching. I am thankful for all the time Sir devoted to meet up with me multiple times a week so that I would be able to catch up with the syllabus. While weakness in Math since Yr 5 led to my fervent dislike of the subject, as Sir guided me in understanding and applying content to the questions in an incremental process, I became more interested in math and even started enjoying working on math questions.

Apart from teaching the syllabus like most teachers, Sir also explained how mathematical concepts were present in real-world situations which helped me to appreciate the math that I was learning. Moreover, I wish to reiterate how grateful I am to Sir. Due to my initial lack of content, Sir had to repeat basic concepts quite a few times as I took time to grasp it. Despite this, Sir was very patient and encouraging, giving me time to absorb his teaching by explaining how to solve a question until I clearly understood. Sir always made me rack my brains over difficult questions before guiding me to the solution. I appreciate Sir's teaching style as it taught me how to think through what I had learnt before and break down the question to see how I could apply the knowledge I had. At the end of all the lessons, I had not only improved drastically in math, I had also gained a newfound appreciation of the subject as well as valuable life skills.

Starting my HL Math course I was quite confident in my personal abilities, a sentiment that turned out to be highly misguided. My first asessment resulted in my school teacher reluctant to allow me to continue in the course, it was then I sought out help and found Mr.Goh. He was able to identify my weaknesses and drill into them, even when I was reluctant to face my own deficiencies. His deep knowledge of the IB was integral in the formation of my IA, namely in topic selection and learning efficient mannerisms to display mathematical  content. Through the aid of Mr.Goh I was able to progress from fearing failing HL Math to receiving a six.

Dear Mr Goh,

I am writing to let you know how much our son, Gareth has benefited from and enjoyed his classes with you.

Through your knowledgeable experience, passion and guidance, Gareth exceled in his recent IB Math examination on May 2019, and achieved a perfect score of 7. As parents, we were thoroughly overjoyed with his accomplishment, as it has not been an easy journey for him to attain this result.

Without a doubt, we would confidently recommend you to other parents/students who wish to excel in their IB Math program. We believe that the students under your tutelage will excel equally well just like how Gareth did in his paper.

Thank you, Mr Goh, for all of your work, sacrifice and energy! Thank you for tapping and unleashing the inner potential in Gareth.

Mr Goh is an excellent Maths teacher, with a well-deserved pedigree under his belt.

Being an ex-teacher from 3 different JCs and an world-renowned IB school, he clearly understands the syllabus and the questions posed by both Cambridge and the IB board. In this way, he is very in-touch with the current syllabus and thus able suitably predict the types of problems thrown by the respective examination ministries.

He is currently teaching in a reputable international IB school. He managed to boost my U grade in Maths during my J1 year to a B in J2 prelims, with me even securing a place in the 80th percentile. This eventually resulted in me obtaining an A in my A levels examination for Maths, and it was all thanks to Mr Goh’s teaching and hard work.

He is very knowledgeable in mathematical concepts and will not hesitate to start from the very fundamentals in order to allow the student to further understand and grasp the concept. His explanations were always easy to grasp and apply in examinations. But yet at the same time, he will not spoon-feed you and will require you to work on your own to solve challenging questions once the explanations were given, in this way I was able to better understand the intricacies of Maths and not just rely on fixed formulas or stratagems.

Through this way, I developed a greater understanding of concepts thus allowing myself to solve or at the very least set up the thinking process in order to solve the problem.

Moreover, he is a very understanding teacher, he understands the rigour of being a JC student and urged me to not only focus on my maths but my other subjects as well. He manages to build strong rapport with his students by not only teaching very well but also spends time to talk about other real world topics that will be very valuable in the working world.

It is a joy to learn from Mr Goh and I would like to thank him for being an overall great tutor!

Mr Clifford Goh has helped me a lot with my Mathematical Exploration.

Initially, I did not have much understanding about this component of HL Math and was unable to even submit a sound proposal to my teacher. However, Mr Goh went through a thorough revision of the HL Math syllabus for the core topics and this process helped me identify a topic which I was keen in exploring.

While Mr Goh guided me throughout the entire process, he also gave me lots of opportunities to explore new knowledge for myself. When it comes to the proving of formula, he did not just spoon-feed me with the answer. Rather, he worked alongside me, giving me time to try proving the formula myself first, before helping me when I got stuck halfway through.

Overall, I have learnt a lot from the M.E. and this process has been pivotal in inculcating in me a love for math. Mr Goh is definitely a great math teacher, and it would have been impossible for me to obtain a 7 in HL Math without his guidance for M.E.!

Mr Goh was an excellent math tutor, both in terms of the content which he taught us as well as interacting with us cheerfully.

He helped both my friend and I develop a solid foundation for the Math HL subject, as well as guided us as we worked to complete the Internal Assessment. He thoroughly covered both the core and option sections of the HL syllabus, first in a lesson format before going taking up a Q and A style as our exams drew near.

For example, he also paid extra attention to our statistics option, which was the area in which I was weakest in. The thing which separates Mr Goh from other math tutors was his desire and openness to teach us concepts which were out of the syllabus, so as to inculcate a love for mathematics as more than just a subject. Furthermore, he is also familiar with all aspects of the HL mathematics syllabus, which makes him an ideal tutor for students regardless of their mathematical ability.

I had had many tuition teachers before Mr. Goh but I was still unable to bring my Math grade up.

At the time, Mr. Goh was already teaching Higher Level Mathematics at ACS Independent so he was already well versed with the IB programme and what was required to get a high score in the subject. This meant that he was always on the ball with me and was able to provide help in all aspects of the course which included my Internal Assessment (Mathematical Exploration).

Mr. Goh made it a point to explain to his students not only how but also why concepts in Higher Level Mathematics work. This in turn allowed me to attain a deeper understanding of the various topics and thus, little was left to memory work. This was especially effective since the questions in the examination could become extremely challenging.

Having taught IB for several years, Mr. Goh understood how demanding the subject was. He explained that Higher Level Mathematics was a subject that required three times the amount of time for study and practice as compared to any other subject. Thus, he always made sure that I had more than enough practice. With his help, I was able to tackle any question.

It was a pleasure to learn from him. Above all else, Mr. Goh taught me discipline and focus, lessons that I cherish.

“Thank you for being such an inspiring teacher. You have made Mathematics more intriguing and shown me the way to explore it on my own. Seeing a proof to a problem is not as satisfying as producing one myself, and Mathematics – the basis of all Sciences – is more enjoyable that way.” – Tri (ACSI)

“In the beginning of JC 1, I was struggling with mathematics as I was always weak in maths.

Mr Goh always made his lessons so interesting with so many stories that tied it so nicely with the concepts he was trying to put across. He is always ready to answer all my questions and go through all the concepts time and time again because I missed many lectures in jc due to cca commitments.

He made me improve tremendously and he also sparked an interest in me for the subject. His refreshing lessons left me in awe every week waiting for the next one to come to ask more questions and find out more.

My grades improved and I finally graduated with an A grade in A levels 2013.”

“Mr Goh is an excellent Mathematics tutor who has ample knowledge about the subject and the requirements of the curriculum.

I had difficulties understanding Mathematics in the past but Mr Goh’s clear explanations have helped me understand the subject much better and my results have improved. The honest feedbacks and tips he has given me regarding my performance in school tests and practice papers has effectively helped me learn my mistakes and brush up on certain areas that I am weak in.

I may be still failing or barely passing Mathematics if not for his great teachings. Thank you for everything and helping me to obtain grade A for H2 Mathematics.”

“He (Mr Goh) puts in a lot of effort into ensuring that students are taught through understanding, not just by memorizing. He applies concepts taught in class to real life situations, that make lessons very interesting. He encourages us to learn independently and not limit the study of Maths to just classroom setting.”
