Online A-Math Tuition in Singapore: One-to-One and Small-Group Tutors for Sec 3 and Sec 4

A-Math is the upper secondary elective that brings in calculus, logarithms and trigonometric identities, and it lays the ground for H2 Maths in JC. onlinetuition.sg matches Sec 3 and Sec 4 students with A-Math tutors for live online lessons, one-to-one or in small groups, at G3 or G2.

About the A-Math Exam (G3 Additional Mathematics)

From 2027, A-Math is examined in the SEC as G3 Additional Mathematics (K341), with the same content and papers as O-Level Additional Mathematics (4049), which students sat until 2026. It assumes the whole G3 Mathematics syllabus.

Syllabus
G3 Additional Mathematics (K341) from 2027; O-Level Additional Mathematics (4049) until 2026
Paper 1
2 h 15 min, 12 to 14 questions of up to 10 marks each, 90 marks (50%)
Paper 2
2 h 15 min, 9 to 11 questions of up to 12 marks each, 90 marks (50%)
Calculators and formulae
An approved calculator for both papers; the relevant formulae are provided
What is assessed
About 35% standard techniques, 50% solving problems and 15% reasoning, including proofs
G2 Additional Mathematics (K232)
Two papers of 1 h 45 min and 70 marks each, written to prepare students for G3 Additional Mathematics

E-Math content is not tested directly, but the syllabus says it may be needed in questions on other topics, so a weak E-Math topic can cost marks in A-Math.

Common Challenges A-Math Students Face

A Big Step Up From E-Math

A-Math moves quickly from familiar quadratics to surds, polynomials, partial fractions and logarithms.

Trigonometric Identities and Proofs

Six trigonometric functions, the addition and double-angle formulae, and proving identities line by line.

Calculus From the Start

Differentiation rules, connected rates of change and areas under curves, none of which E-Math covers.

Proofs in Plane Geometry

Writing a full proof with the midpoint theorem or the tangent-chord theorem, with a reason for every line.

Curves Turned Into Straight Lines

Rewriting a relationship in linear form, then reading its unknown constants from a straight-line graph.

Long, Multi-Part Questions

Paper 2 questions carry up to 12 marks each, and an early slip can cost the parts that follow.

How Our Online A-Math Tutors Help

Algebra Foundations First

Surds, indices and factorisation brought up to speed before the harder topics build on them.

Identities Proved Step by Step

Each line of a proof written out on the whiteboard, with the identity or formula it uses.

Calculus With Clear Methods

The chain, product and quotient rules practised until they are routine, then applied to tangents, normals and maxima.

Graphs Sketched Live

Trigonometric, exponential and logarithmic graphs drawn on screen, so amplitude, period and symmetry are easy to see.

Technique for Long Questions

Reading every part before starting, and carrying exact values through to the end.

A Head Start for H2 Maths

Secure A-Math skills, which the H2 Mathematics syllabus lists as assumed knowledge for JC.

A-Math Topics Covered by Our Tutors

G3 Additional Mathematics topics in the syllabus's own words, under its three strands. The syllabus does not split them by school year.

Algebra

  • Quadratic functions
  • Equations and inequalities, including conditions for real roots and quadratic inequalities
  • Surds
  • Polynomials and partial fractions
  • Binomial expansions
  • Exponential and logarithmic functions

Online E-Math tuition

Geometry and Trigonometry

  • Trigonometric functions, identities and equations
  • Coordinate geometry in two dimensions, including the equation of a circle and relationships turned into linear form
  • Proofs in plane geometry

Calculus

  • Differentiation and integration, applied to tangents and normals, rates of change, maxima and minima, areas, and a particle moving in a straight line

Online H2 Maths tuition

G2 Additional Mathematics

G2 Additional Mathematics (K232) covers quadratics, surds, polynomials, trigonometry, coordinate geometry and the calculus of powers of x. Among the G3 topics it leaves out are binomial expansions, exponentials and logarithms, plane geometry proofs, and the calculus of trigonometric and exponential functions.

Frequently Asked Questions About A-Math Tuition

Thinking of A-Math Tuition?

Is A-Math Much Harder Than E-Math?

It is more abstract. A-Math adds calculus, logarithms and trigonometric proofs, and its questions are longer, with up to 12 marks each in Paper 2.

Should My Child Take A-Math?

The syllabus is written for students with an aptitude and interest in maths, especially those heading for the sciences or H2 Maths. Your child's school will advise on subject choices too.

When Should My Child Start A-Math Tuition?

Early in Sec 3, when A-Math begins, or as soon as test marks dip. The topics build quickly, so gaps are easier to close early.

Can One Tutor Help With E-Math and A-Math?

Yes, where possible. A-Math relies on E-Math algebra, so one tutor can strengthen both; tick both subjects in your request.

Does A-Math Matter for JC?

For H2 Maths, yes: the H2 Mathematics syllabus lists O-Level Additional Mathematics content as assumed knowledge.
