Improving confidence and grades in Math

Mr Ang taught me during my upper secondary years and without doubt, my Math grades have improved by leaps and bounds. Initially, I was failing A-Math before I came here, but my grades became better within a few months. Mr Ang’s lessons are also really interesting, and I find his style of teaching very unique and special, utilising technology and redefining the process of learning math.

His lessons are engaging and helpful for exams for me.

Mr Ang is a teacher who always teaches us the shorter and easier methods to solve questions by teaching us shortcuts which were very helpful for me during exams as it saves a lot of time. During lessons, he also adds on questions by himself to let the class think deeper into a certain question and concept which actually helped open our eyes to a whole new method and thought. His classes are hence very helpful and are definitely worth the 4 hours a week!

I have really improved

I have really improved in my math during my time at numberskill Math tuition. Mr Ang is able to teach the math concepts and problems in a very fun and interactive manner. This has allowed me to really understand the concepts and helped with my math. It was a very enjoyable experience at numberskill.

Couquering of maths

I joined this class during my secondary two December holiday. My maths were really terrible back then. After attending Mr Ang’s class for almost a year now, I have certainly improved on my math skills and I’m much more confident in maths now. He is a caring and hardworking teacher who is always willing to teach us beyond our stipulated lesson time.

My grades for Math has only improved

Mr Ang never follows the rigid structures of the notes most schools provide. Instead, he simplifies novel concepts and delivers them in such a way that every student understands. Although these concepts are simplified, they are as in depth as the schools notes. He also ensures that every student understands and is able to solve the various question types before moving on in the lesson. In fact, I learn more here than in school. Apart from the teaching, the environment too greatly suits learning.

That’s why in the 5 years I have been with him, my grades for Math has only improved.

ACJC 2013

Thank you, Mr Ang!

Thank you, Mr Ang, for being a dedicated teacher who never fails to make math more enjoyable! The lessons are very fun and the structure of the lessons is well paced such that I am able to follow the lesson as well as understand the content! I am grateful that you put in the extra effort to answer our all extra questions! Thanks again Mr Ang!

A1 for both A and E math in the “O” levels!

Before I came here, I was really bad at math. I always failed my A math and could not pass any tests in school. I was always getting F9 for tests and that made me very demoralized. However, after I joined Mr Ang’s tuition, I improved by leaps and bound. I got an A1 for Emath, A2 for A math for my prelims and eventually got A1 for both A and E math in the “O” levels! Thank you Mr Ang!

Thanks for guiding me to distinctions in both O and A levels!

Mr Ang, just want to say thank you for your guidance for the past 5 years. I really enjoyed your lessons. Thanks for guiding me to distinctions in both O and A levels! Do continue to help more students achieve As!

I am very grateful

I am very grateful to Mr Ang for his coaching in Maths, as he makes JC Maths easier to understand. The notes he gives are comprehensive yet covers the primary skills for each topic, that I do not feel overwhelmed by the sheer amount of things I need to learn per topic. But of course, merely reading the notes will not go far without the fiery passion provided by the tutor. In this department, Mr Ang does not disappoint! His enthusiasm in Maths coupled with his understanding of the problems students today face with the JC Maths syllabus makes him, in my opinion, one of the most dedicated and patient tutors I have learned from. I am especially delighted that given my hectic schedule juggling between A levels and National Service, thank god, Mr Ang has live online lessons and video lectures I can review to fit into my schedule.

Being able to relate to students’ problems in Maths, breaking down seemingly complex problems into simple concepts and a burning passion towards Maths combined with utilising the power of technology into classroom teaching has made Mr Ang’s Maths lessons a joyful experience. I do not promise that Maths would be a breeze under his tutelage. But I can assure you the road ahead towards that A would be less bumpier with his guidance.

To Mr Ang, thank you for your patient guidance! I hope to make you proud in my A levels, no matter how much I struggle with my time management. To prospective students, I do not hesitate to recommend NumberSkill as the right tuition for you! May Mr Ang inspire you to love Maths, as he has done for me.

Mr Ang is a very engaging teacher

Mr Ang is a very engaging teacher and he always makes sure that his students understand the concept fully before moving on. He’s also very patient and is willing to take the time to go through concepts that you’re unclear about. He also helps students to truly understand the concepts behind each topic so that the students know what they’re doing instead of just blindly solving questions and putting in formulas without knowing what they mean. This has helped greatly in my understanding of math. Thank you Mr Ang!

Best Math Tuition

Every lesson is well-crafted and well-paced.
Dedicated and professional teacher.
This is the best math tuition that I have attended.

Fervent & fuelled passion for maths

Mr Ang is a superb immensely dedicated and highly passionate mathematics teacher! I’m the only student from the East side who would have the “sanity” to travel 20km tö and fro each for his lesson, as the distance traveled is well paid off during lessons- his concise teachings & constant reminders of common conceptual mistakes are deeply engraved in my mind. He also offers personalised consultation on whatsapp and is very prompt to reply to any queries we have regarding school work/our revision. He allows those who were relatively new in JC2 to freely attend JC1 lessons to concretise & reinforce our JC1 topics. For that I am greatly thankful to Mr Ang for making maths lessons really engaging & thrilling with anticipated challenging AJC questions posed to us weekly(and many more).

Lim Yi Xuan

Solid foundation for each topic

Mr Ang is a dedicated, down-to-earth, inspiring and patient tutor who helps students to easily assimilate complex mathematical concepts without losing depth, which is essential in order to score for H2 Math. Many who are struggling with H2 Math (like myself) would understand that confidence, coupled with the right amount of the right type of practice are often lacking, which results in undesirable grades. Mr Ang’s lessons effectively tackle these areas of weaknesses, but it doesn’t stop there – he makes a point to instill in every student a solid foundation for each topic (that your school won’t really teach) and relate these mathematical concepts to real-life, which is especially important in the revised 9758 syllabus. The enriching yet entertaining lessons effectively encouraged me to press on and realise that there is nothing that cannot be solved if you really know the principles behind what you’re learning. Thank you Mr Ang for all the help you have rendered in the arduous 2 years of JC!

2017 SRJC

I attended Mr Ang's lessons throughout my 2 years in JC

I attended Mr Ang’s lessons since early J1 and Mr Ang’s weekly lessons really helped me in my understanding of math. Throughout the 2 years, his lessons were always very interesting and fun. They also gave me many opportunities to clarify my doubts and exposed me to different types of challenging questions. His humour also helped to make the lesson more lively. Mr Ang’s detailed notes are very useful and he is also always willing to help us out when we have extra questions to ask. Thank you Mr Ang for the enriching experience!

Thank you Mrs Ang

Although it’s only been a few months since I have joined Numberskill’s Chemistry tuition class, I am really glad that my confidence in the subject has gone up and I have seen a significant improvement in my test results! Mrs Eileen Ang is a very caring teacher who never fails to make lessons enjoyable for us, and through her lessons I have managed to grasp Chemistry concepts much better and the extra worksheets also provide good practice. Thank you, Mrs Ang, for all your help and guidance!

Clarissa Aw Yuan Ting

Inspiring teacher, motivated student

Thank you Mr Ang for making lessons fun without losing focus on the lesson. I was always shocked how math could be solved in those different ways. Thank you for reigniting the spark in me for math and giving me the motivation to do well in that subject!

I regained confidence when doing Math

I joined numberskill math tuition at the start of my JC2 year, having done poorly for math in my JC1 year and it was not long after which I regained confidence when doing Math. Mr Ang thoroughly and patiently goes through every concept in the syllabus and ensures that we won’t be stumped by any questions due to poor grasp of concepts. He offers his free time after lessons to answer student’s questions and often offers extra lessons for newcomers and students who still have doubts in certain topics to ensure that no one is left behind in class. He also offers other forms of catching up such as video recordings of every lesson, which are made available for students to view if the need arises. Aside from his care for all his students, he is also a great educator and uses a variety of methods to approach the concepts taught, catering to all students with different learning styles. He often probes students to actively think and participate in the lessons, and never puts us down when we make mistakes. He is also systematic and extra lessons and fees payment hardly cause any confusion or trouble for students, if ever! ^^

Mr Ang teaches interestingly

Mr Ang is very nice and teaches interestingly. He links O-level concepts to A-level topics, this helps students bridge the gaps more easily and understand the new concepts more readily. He also gives a variety of tutorial questions, exposing students to different types of questions.

Mr Ang is a very diligent and motivated teacher

Mr Ang is a very diligent and motivated teacher who puts in his best effort in equipping his students with relevant skills for math. His teaching is also clear, simple and suited to the understanding of students. At the same time, he is approachable. I am able to inquire about any queries I have during lessons or simply just by sending him a text. Under Mr Ang’s guidance, I had better grasp of math concepts and the confidence to tackle any questions.

Mr Ang is a dedicated teacher willing to go the extra mile for his students

Mr Ang is a dedicated teacher willing to go the extra mile for his students. He shows care and concern for his students and tries his best to help us understand the math concepts. His creative methods and simple tricks allow me to remember my work better. Before I went for Mr Ang’s tuition, I struggled with my math but through his help, I was able to improve both my maths to an A1 grade for my prelims. My 3 years with Mr Ang was an enjoyable and fun-filed years as he made math interesting and seemed manageable.

Thank you Mr Ang for your help in getting the As in O levels.

I have greatly enjoyed my lessons with Mr. Ang

I started with Mr. Ang during my JC1 year and he has helped me greatly in understanding concepts and in solving questions. His style of teaching is easy to grasp and he will patiently explain the same question until it is completely understood by each student. Although sometimes we encounter very tricky questions, he never fails to solve them and teach us the different methods of coming to the final answer. He also gives us papers of different difficulty levels so we get to try out all the possible kinds of questions that could come out. I have greatly enjoyed my lessons with Mr. Ang. He has been an excellent teacher.

I am very glad I joined Number Skill

I am very glad I came across that advertisement that made me enroll to here. Without Mr Ang’s support I really don’t think I would have gotten such a strong foundation for math. Mr ang makes concepts very clear and provides useful tips to help us remember them well. I highly recommend Numberskill for those seeking significant improvements in math!

CJC 2017

Highly recommended!

Mr Ang has been a very helpful and patient teacher, with a friendly personality, students in his class will not feel discouraged to approach him. With all the recorded lessons, I can catch up with whatever lessons I have missed or are unsure of and also through WhatsApp I can clarify my doubts as soon as I have any, I would totally recommend Number Skill to other students. Thanks a lot Mr Ang 🙂

After attending Mrs Ang class,

After attending Mrs Eileen Ang’s Chemistry class, I realised my concepts for the chemistry topics became very clear, hence, I do not need to keep referring to my notes while doing worksheets during revision. Her lessons helped me a lot!

Grateful for having him as my teacher

After joining Gary in JC2, I immediately felt a difference in the way I grasp mathematics. Gary teaches with different techniques to help students grasp concepts in each topic. I always thought Maths did not need understanding but I realised I was wrong when I joined his tuition class. He prepares his lesson well and his resources are very useful. Moreover, Gary is a very kind and patient teacher, who is always willing to help his students whenever and wherever. I am really grateful for having him as my teacher.

What is the need for school when you have Mr Ang?

When I joined in secondary four, my EOY results for the previous year was an E8. I felt discouraged and only hoped for a B3 during my O levels. After joining Number Skill for only a few months, my mathematics skills improved tremendously. Mr Ang taught me many tricks and tips that can help me improve my grades. By the time I took my mid year papers, I actually passed! I feel encouraged by his words and I’m confident that it is possible for me to get an A1! With his support and teaching, I think anyone can get their As!

A fun and enriching experience

I have been in Mr Ang’s tuition since secondary 3 and have since followed him all the way up to JC2. I find his lessons very unique compared to other tuition teachers. He engages his students very well and makes learning math fun. He incorporates technology into his lessons which makes learning much more engaging. I always look forward to his tuition classes every week because I know that my 2 hours with him is going to be enriching and well spent. He was the one who sparked my interest for math back in secondary 3 when I was doing really badly. I went on and got and A for O levels and A for H2 math in A levels.

Now, I am confident in doing mathematics

Before coming for tuition, my mathematics results was not really up to standard, getting B or C when I was in secondary 2 in 2010. After joining numberskill, my mathematics results improved. Mr Ang is a patient tutor who will teach me till I understand. He will go through the topic before every of my class test. He will teach us short cuts like synthetic division and cover-up rule so that I can save time during my examinations. For the past 4 years, he did not give up on me and tried his best to help me reach my aims. Now, I am confident in doing mathematics after joining numberskill.

Mr. Ang not only teaches but touches hearts

Mr. Ang is a motivating and dedicated teacher. Because of Mr. Ang, I have gained a lot of knowledge about math, especially simple and concise way of solving the most complicated questions. He makes lessons enjoyable, and at the same time, fruitful, as we learn. Other than his knowledge and skills that he has imparted to me, he has definitely gave me something that cannot be measured through the results I have achieved: the intense passion for math. All in all, Mr. Ang is an all rounded teacher who not only teaches but touches hearts, with his willingness to spend time with his weaker students and his easy going character.

Mr Ang is a very dedicated and patient teacher!!

Mr Ang is a very dedicated and patient teacher!! He always manages to make math seems fun and easy and more approachable. His belief and confidence in our abilities motivates us to strive for our very best for each exam/test!! Not to mention he always forks out time for us outside tuition lessons to answer our questions amidst his busy schedule. His lessons are very enjoyable. He also puts in a lot of effort to make his lessons interesting and thus every lesson is very enjoyable and always filled with joy and laughter 🙂 Mr Ang is also a very tech savvy person!! The way he incorporates technology with math has helped me view math in a totally different light. Like which math teacher would literally draw out a 3 dimensional plane, painstakingly plotting out all the points, just to aid your visual learning?!?! You only get this at numberskill Math Tuition.

Although it has only been a few months since I have joined Numberskill’s Chemistry tuition class, I am really glad that the lessons have helped to raise my confidence in the subject and I have also seen a significant improvement in my test results! Thank you, Mrs Ang, for being such a caring teacher who makes Chemistry lessons so enjoyable and beneficial for us! Now, I am able to grasp Chemistry concepts much better and the extra worksheets we do in class provide great practice! Chemistry has become one of my favourite subjects through attending the classes, and I am really thankful for Mrs Ang’s guidance and help!

Effective and helpful tutor

Mr Ang is a dedicated teacher who will readily help you, even after class, with any math question you’ve faced while revising. Before attending Mr Ang’s lesson, I have always doubted the effectiveness of a class tuition. However, i was wrong after attending his lesson. Mr Ang usually keeps his class size small to ensure that each student will comprehend the concepts extensively. His notes includes questions of varying difficulties for greater exposure. Also, every lesson is recorded and uploaded for the convenience of students who wish to re-visit a certain concept. With his guidance, my math has improved greatly. Thank you Mr Ang!

From zero to A1 and A2 in “O” levels

Before I came here, I was really bad at math. I got zero for E math and A math at the start of the year and I was at a loss of what to do. That was when my friend referred me to numberskill. Before the first lesson, I had the impression that math tuition would be dry and boring. I though it would be difficult to catch up on my math grades with only 8 months left before my “O” levels. In Mr Ang’s class, it is also possible to have fun while working hard. All in all, if you go for Mr Ang’s class and you put in the effort, nothing is impossible. If there were any math tutor I would refer people to, even if I were asked 1000 times, I would recommend Mr Ang’s class. From zero to A1 and A2 in “O” levels, I’m not joking.

Having struggled in Chemistry in school, I am glad to say that under Mrs Ang’s tutelage, I have seen an improvement in my test results!
Even though it’s only been a few months since I joined Mrs Ang’s Chemistry tuition class, I am clearer with my concepts and have gained skills on how to apply this knowledge to score for my paper. Thank you Mrs Ang for decoding Chemistry for me and never failing to make every class fun!

Notes are succinct and easy to understand

Mr Ang’s lessons had always helped me to understand each topic fully. His notes are succinct and easy to understand, even for the difficult topics. Hence, Mr Ang’s notes were always on hand right before I enter the examination hall, to help me remember the skills I needed for the math paper. The board that Mr Ang uses goes a long way in helping me visualise some concepts. The fact that all his lessons are recorded for me to watch them again also helped me in my topical revision closer to A levels. In addition, his lessons were always a joy to attend, as his jokes and friendly personality makes the class atmosphere light. This also made me feel more comfortable to ask questions and clear any doubt I had. With the materials Mr Ang gives and his passion for teaching, it’s hard not to be more confident in my ability in Math.

Mr Ang is an extremely dedicated and patient teacher

Mr Ang is an extremely dedicated and patient teacher who constantly extends tuition sessions just to make sure we cover more content. It is rare to witness such selflessness where a teacher extends lessons up to even an additional of 2 hours without complaint or cost. Every lesson he teaches testifies to his sincere desire for each student to do well. He does not turn anyone down regardless of how “silly” a question might seem and he would share challenging questions with us if he does come across any so as to better the class’ standards as a whole. I am very grateful to be under Mr Ang’s guidance and care as he is not only dedicated but proficient in teaching math. What makes a good teacher is not only his qualifications but his ability to teach and Mr Ang certainly has both qualities. Mr Ang has a dearth of resources for practice and each topic is taught in a structured way which helps students cover the entire syllabus with ease. Furthermore his classes are always taught in an enjoyable and relatable manner; we as students look forward to going to tuition with him as he never fails to cause an eruption of laughter in class while acquiring the necessary skills and knowledge for math. I have certainly improved by leaps and bounds under Mr Ang and 10/10 I would recommend students weaker in math to join Mr Ang’s classes 🙂

Your math lesson has greatly improved my understanding of mathematics! Even though I joined pretty late, I can feel the improvement in my mathematic. I’m now more confident in doing math questions and I got a B for math! I was a straight U or S student for math throughout JC… Thanks a lot for your guidance!

Improvement in math

I joined Mr Ang’s class when I was in secondary three. I was not even passing my math examinations in school and I really felt that I had no hope for math and that I was not a math person at all. However, after joining his class, I slowly felt more comfortable towards doing maths. This is all thanks to Mr Ang who is always willing to help in and out of class whenever I have any questions.

For our on-site classes, we make sure to deliver our lessons in a structured and engaging way to ensure effective learning. With every session, you can expect a small class size as we make sure that each student’s learning needs are met. Our tutors employ various teaching strategies to cater to different learning styles and abilities, making certain that no student is left behind. For our online Math and Science tuition, you can watch our livestream through Microsoft Teams and get video recordings of past sessions. Notes will also be available to them on OneNote. Should you have doubts or questions about certain topics, you can schedule a one-on-one lesson with our tutors.
