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.

Mr Goh has a strong grasp of mathematical concepts and often encourages us to not only memorise but truly understand how various mathematical formulas are derived so we can better apply them regardless of the question type.

He is also a passionate teacher that frequently gives us thinking questions to stretch us and challenge our understanding of fundamental concepts. He then shows us more than a single method of solving the question, allowing us to broaden our thinking and better appreciate how different topics are inter-related.

His help enabled Kai Le to improve from B in PSLE to A1 and A2 for E Math and A math in O levels respectively. Kai Xuan also managed to attain A for H2 Math in A levels.

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 is a passionate teacher who has helped me through both my Mathematical Exploration (ME) and my HL Math papers.

Being his student for a year, he has helped me tremendously in my understanding of complex mathematical concepts and also have a greater appreciation of the subject.

During his lessons, he uses interesting stories to illustrate certain topics which was very useful for Statistics in particular. He has the ability to engage me and even reignited my passion for this subject. Meanwhile, for my ME, he helped me by first providing a large range of possible ME ideas, where he advised me along the way to best cater to my expectations and interests.

Following, he continually guided me in my report writing by providing assistance throughout the process. Instead of simply spoon feeding me, he has effectively allowed me to explore the solutions by myself before he clarifies my doubts, explaining it to me patiently till I can fully comprehend it.

Mr. Goh is truly an inspiring teacher who has assisted me greatly through my HL math journey. Without his efforts and guidance, I will not be able to improve impressively to eventually attain a 7 in my IB exams.

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 am thoroughly thankful to all the help he gave me throughout my IB journey, and I strongly recommend other students interested in tuition to contact him.

Thanks Sir, although I couldn’t get 7 still thankful for the guidance

Mr Goh is very knowledgeable about various topics in mathematics – often being able to relate many different concepts together.

Many lessons included applications of the mathematics I am learning in school to real life which helped make the lessons alive. Not only is he strongly grounded in what he teaches, he clearly explains and guided me well throughout the lessons, helping me to fully understand what was being taught.

With him, I could learn cover the topics necessary well and in a timely manner as well. He also responded well to questions given to him even when it might have been out of syllabus or he might have been unprepared for it.

Overall, I am very glad to have been taught by Mr Goh.

“Mr Goh imparted me with a strong foundation in mathematics.

He made sure that I completed the assignments on time and achieved my goals in a steady manner. His passion for mathematics made the subject so much more engaging and boosted my appreciation for mathematics as well.

Due to his skills as a teacher, I was always more eager to wait for his classes to ask him my doubts, as he would show me not one, but multiple ways to answer the same question. This ensured that I did not just memorize the solution, but assimilated the logic appropriately.

Mr Goh also provided me with useful resources, which would ensure that my understanding of mathematics was not just limited to the exam board I was writing for.

Thanks to him, I was able to get a 7 in HL mathematics, and secure the top marks in my cohort for Year 6 in the IBDP Program. Thank you for enabling me to persevere and ace in maths. ”

“Mr Goh is well versed in mathematics and is able to correctly identify weaknesses in his students.

His notes are concise and easy to follow, the follow up questions help to clear doubts and correct any misconceptions early. He also fuels my curiosity as he explains concepts which are not required within the syllabus but help me to understand what I learn better.

Instead of spoon feeding, he let me explore different concepts by myself , giving me a deeper understanding of math and guiding me through the process. Concepts became easier to understand.

His practices demanded diligence and self discipline, which is an important trait to ingrain. It allowed me to practice continuously and stay in touch with math.

Thank you for your help and passion in math which helped me get an A in H2 math for the A levels”

“At the end of 2014 I was looking for a Higher Level Mathematics teacher seeing as how I had failed the year end examination. After some searching, my father had seek the help of Mr. Goh.

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 bringing a failing student to a grade 6 (A); this was done in less than a year’s time.
