A-Math Tuition Singapore
Additional Mathematics (A-Math, syllabus 4049) is the O-Level subject that decides whether a student can take H2 Math at JC. The Annexe Project’s Amath tuition is a live, small-group online class for Sec 3 and Sec 4 students, taught by founder Mr Alvin Yeo for 1.5 hours a week. 77.5% of the 2025 cohort scored A1 or A2. Fees are SGD 260 per block of four weekly sessions, notes and recordings included.
★★★★★ Rated 5.0 on Google from 45 reviews · Founded 2008 · Taught by Mr Alvin Yeo
- Full O-Level Additional Mathematics syllabus (4049): algebra, trigonometry, geometry proofs and calculus
- Methods made simple and repeatable under exam pressure, with every marking-scheme step shown
- Recorded, downloadable lectures plus free consultations between classes
- Weekly practice and homework reviewed by the tutor; timed drills before the O-Level
Who this class is for
- Sec 3 students meeting A-Math for the first time and finding the pace faster than E-Math
- Sec 4 students sitting the O-Level this year who need the A1/A2 that opens H2 Math at JC
- Students who have failed or scored C5–C6 in a school A-Math paper and need a method reset (see Keith’s story below)
- IP and international-school students preparing for the Cambridge 4049 paper
Syllabus topics covered (4049)
Algebra
- Quadratic functions, equations and inequalities
- Surds and indices
- Polynomials, remainder and factor theorems, partial fractions
- Binomial theorem
- Exponential and logarithmic functions
Geometry & Trigonometry
- Trigonometric functions, identities and equations
- R-formula and further identities
- Coordinate geometry, including circles
- Proofs in plane geometry
Calculus
- Differentiation: chain, product and quotient rules
- Tangents, normals, stationary points and rates of change
- Integration and areas under curves

What a lesson looks like
- Notes arrive before class. Structured lecture notes curated by Mr Yeo, so nobody scrambles to copy from the screen.
- Live working on a digital whiteboard. Every question is solved line by line in the marking-scheme format, and students ask questions out loud or in the chat.
- Weekly homework, reviewed. Practice during the lesson plus a homework set marked by the tutor, so gaps show up early.
- Recording and consultations. The lecture recording is downloadable for the whole course, and free consultations outside class have been the academy’s culture since 2008.

Common questions
How much does A-Math tuition cost?
SGD 260 per block of four weekly sessions of 1.5 hours (SGD 65 per session), with structured notes, homework review and lecture recordings included. Trial lessons are available before you commit.
Who should take A-Math tuition?
Sec 3 and Sec 4 students taking O-Level Additional Mathematics — especially those aiming for the A1/A2 needed to take H2 Mathematics comfortably at JC, and those whose school grades have slipped to C5 or below.
Can a student who is failing A-Math still get an A1?
Yes, with a method reset and weekly practice. Keith Ng came to us failing A-Math and scored A1 at the O-Level after a few weeks of intensive lessons; the class rebuilds each topic from the question types that appear in the paper.
What is the difference between A-Math and E-Math?
E-Math (4052) is the compulsory O-Level mathematics paper; A-Math (4049) is the additional, more abstract paper covering calculus, trigonometric identities and proofs. A strong A-Math grade is what JCs expect from students who want to read H2 Math.
Are A-Math classes online?
Yes — live over Zoom in small groups, so the tutor sees your working and corrects it on the spot. Notes are sent before each class.
What happens if I miss a lesson?
Every lesson is recorded and downloadable, and free consultations outside class time are always available.
How is the O-Level A-Math paper structured?
Two papers, each 2 hours 15 minutes and worth 90 marks. Paper 1 and Paper 2 both draw on the full syllabus, so the class covers every topic before moving to timed practice.
Should my child start A-Math tuition in Sec 3 or Sec 4?
Sec 3, if possible: the topics build on each other (surds and indices feed logarithms; trigonometry feeds calculus). Sec 4 students can still join — they receive recordings for earlier topics and a consultation to catch up.
