 recommendsTrustindex verifies that the original source of the review is Facebook. As an upper sec math student taught by Ms Celia Chia, I can indeed say that the tuition centre is well equipped in preparing students for their exams as well as their general knowledge and grasping of the subject. Mathematics is essentially about practice and Orion really provides ample and well planned out materials to ensure we are familiar with concepts of the subject. The flexible, affordable and well paced (with respect to schools) lessons ensure we are ready while the teachers are attentive and understanding of issues we face and really go the extra mile to ensure we do well instead of merely going through the process of narration.

 recommendsTrustindex verifies that the original source of the review is Facebook. Mr Anthony and Ms Agnes are passionate teachers who went out of their way to conduct extra sessions for my daughter to strengthen her foundation. My daughter comments that they were able to explain her misunderstandings to her clearly, and motivate concepts effectively as well. My daughter's confidence level has visibly increased after attending this tuition centre. With these in mind, I would strongly recommend this centre to others.

 recommendsTrustindex verifies that the original source of the review is Facebook. The Teachers here especially Mr Anthony (Maths and Physics) are extremely passionate and knowledge about the subject that they teach and are really encouraging.Mr Anthony is willing to go an extra mile to ensure that his students are crystal clear in their concepts. He also provides helpful resources (prepared by him)  which enables to understand and follow what is being taught. During the class hours,he answers every question that every student asks and also repeats himself until the student understands fully and he does not leave anyone behind during the class.Also the environment there is extremely conducive to study thanks to the provision of snacks and drinks . Overall I will strongly recommend this tuition to the students

 recommendsTrustindex verifies that the original source of the review is Facebook. We were very impressed with Mr Anthony when he taught my son H2 Maths for the past 2 years. He was able to motivate him. He is also very accommodating and always went the extra mile to help my boy whenever he needs help. Hopefully he will be able to help my girl next year when we enroll her for his class. Thank you Mr Anthony!

 Trustindex verifies that the original source of the review is Google. I was taught Amath by Ms Celia for 2 years. Initially I was struggling with the subject and I wasn't able to understand the concepts, hence I joined Orion for tuition. Ms Celia is a very kind and approachable teacher. She taught the concepts of the subject thoroughly and made sure I understood everything well. She gave us a lot of practices to ensure we become better at the subject. She also always encouraged us to send her questions from school that we couldn't answer or understand and she explained them and helped us solve them. Due to her teaching, I was able to improve greatly in both Amath and Emath and do very well for both of them!

 Trustindex verifies that the original source of the review is Google. At first before I joined, my math results were quite bad as my concepts were very weak. However, after joining the classes, my concepts slowly improved and my results had overall improved. Would highly recommend coming for classes as it was really enlightening.

O Level and G3 A Math tuition: Sec 3 and Sec 4 topics

A Math (Additional Mathematics, or A Maths) is a two-year subject, taught in Sec 3 and Sec 4. A lot of it links back to E Math, so in our A Math classes we also go through the related E Math topics, trigonometry for example. Here are the three main parts of A Math and what is in each one.

x²

Algebra for A Math

Algebra comes first, and the rest of A Math uses it all the time. Schools don’t all teach the algebra topics in the same order, so your child’s school may follow a different order from the list below.

Quadratic FunctionsEquations and InequalitiesSurdsPolynomials and Partial FractionsBinomial TheoremExponential and Logarithmic Functions

sin

Geometry and Trigonometry for A Math

This part is about graphs and angles. Trigonometry goes further than it did in E Math, and the topics follow on from each other, one after another.

Coordinate GeometryLinear LawTrigonometric Functions and GraphsTrigonometric Equations and IdentitiesProofs in Plane GeometryRelated E Math Trigonometry

∫

Calculus for A Math

Calculus is new in A Math, so this is the first time your child sees it. It starts with differentiation (how fast something changes), moves on to integration (areas), then uses both for problems about motion. Each topic follows from the one before.

Frequently Asked Questions

What is O Level A Math (Additional Mathematics) tuition at Orion?

Our A Math tuition is for Sec 3 and Sec 4 students taking O Level Additional Mathematics, including G3 students. Classes run at Toa Payoh and Yishun, and you can also join live online. We cover Algebra, Geometry and Trigonometry, and Calculus. Because A Math links closely to E Math, we also go through the related E Math topics, such as trigonometry.

How is Orion's A Math tuition different from other tuition centres?

Two things matter most: the tutors and the programme. Our tutors have strong skills, track records and experience. We also use many kinds of resources to keep lessons interesting: online video lectures, summary notes, Orion Pop Quizzes and revision assessments. Some of our materials are not available elsewhere.

Should my child start A Math tuition in Sec 3 or Sec 4?

Sec 3 is the better time, because A Math is a two-year subject and later topics depend on earlier ones. Sec 4 students can also join. New students join a new class rather than an existing one. Our Sec 4 lessons balance revision of Sec 3 topics with the new Sec 4 topics. Revision is done in phases, with harder questions each time.

My child's school teaches the A Math topics in a different order. Will Orion's classes still suit them?

Yes. Schools differ mainly in the order of the Algebra topics. Trigonometry and Calculus follow on from each other in the same order everywhere. Our tutors know these differences, and students may be re-grouped or given the option to join another group for the Algebra topics.

Can I see the A Math lesson plan?

We don’t publish lesson plans online, because each class is planned around how that class is doing. For example, if most of the class is comfortable with a topic, we spend less time on it so the others can catch up. In later revision we bring harder questions on that topic back for everyone.

Where and when are the A Math classes, and how much do they cost?

Classes are at Toa Payoh and Yishun, with the option to join live online. See the class schedule at the top of this page. The fee is $360 a month for 4 lessons, with GST absorbed and no deposits. You can try a class first: from November to March the first lesson is a trial, and the fee is waived if your child doesn’t continue. From April to October there is a 3-lesson trial pack.

Is there help outside A Math lesson time?

Our tutors like to go beyond the programme for their A Math students. We often stay back after class to clear doubts, and students are always welcome to approach us. When we can, we also clear doubts over Zoom and WhatsApp. Registered students also have access to the online bite-sized revision lessons with guided practice.
