How to Make Sense of the SEC G3 Additional Mathematics Syllabus in Singapore

The SEC G3 Additional Mathematics syllabus (K341) is the official SEAB document that sets out what students in Singapore are examined on in G3 Additional Mathematics. This guide explains how the syllabus is organised, how the two papers work, what the examiners look for and how families can use the document well.

What this quick-reference guide does: Use this short reference for the official K341 paper specification and assessment objectives. The primary G3 Additional Mathematics guide gives deeper worked explanations of functions, trigonometry, calculus and further-study choices. Match revision materials to the actual SEAB subject code, not merely to a broad Science or Mathematics label.

The K341 syllabus is official.

It is also precise and dense.

It is easy to glance at it once and put it away.

Once you know how it is organised, it becomes a useful map.

This guide is useful for families who need to:

understand what the two K341 papers look like;
check which topics are included and which are left out;
plan revision around the three content strands; or
make sense of the assessment objectives and the formula list.

At eduKateSG, we start from the syllabus document when we plan Additional Mathematics lessons, so that practice matches what is examined.

This guide is based on the SEAB syllabus document examined in 2027. SEAB can update syllabuses, so always check the latest version on the SEAB website.

What the Syllabus Is For

The syllabus is written for students who have an aptitude and interest in mathematics.

It has four aims:

build concepts and skills for higher studies in mathematics, and support other subjects, especially the sciences;
develop thinking, reasoning, communication, application and metacognitive skills through problem-solving;
connect ideas within mathematics, and between mathematics and the sciences; and
appreciate the abstract nature and power of mathematics.

Before it comes G3 Mathematics. The syllabus assumes that knowledge. It is not tested directly, but it may be needed inside questions on other topics.

After it comes A-Level H2 Mathematics. The introduction says K341 prepares students for H2 Mathematics, where strong algebraic manipulation and reasoning skills are needed.

How the Examination Is Structured

K341 has two written papers. The scheme of assessment lists no other component.

Paper 1

Duration: 2 hours 15 minutes
Marks: 90
Weighting: 50%
Questions: 12 to 14 questions of varying marks and lengths
Maximum per question: 10 marks
Choice: none, as candidates answer all questions

Paper 2

Duration: 2 hours 15 minutes
Marks: 90
Weighting: 50%
Questions: 9 to 11 questions of varying marks and lengths
Maximum per question: 12 marks
Choice: none, as candidates answer all questions

Both papers carry equal weight. Paper 2 has fewer questions for the same 90 marks, so each question tends to carry more marks.

The syllabus also states that leaving out essential working will cost marks.

What the Syllabus Covers

The content is organised into three strands, with ten topics in all.

Algebra

quadratic functions, including maximum and minimum values and when a quadratic is always positive or always negative;
equations and inequalities, including the nature of roots and whether a line meets, touches or misses a curve;
surds;
polynomials and partial fractions, including the remainder and factor theorems;
binomial expansions; and
exponential and logarithmic functions, including their graphs and use as models.

Geometry and Trigonometry

trigonometric functions, identities and equations, in degrees or radians;
coordinate geometry in two dimensions, including circles and changing relationships to linear form; and
proofs in plane geometry, using results such as the midpoint theorem and the tangent-chord theorem.

Calculus

differentiation, including the chain rule, products and quotients, stationary points and rates of change;
integration as the reverse of differentiation, and the definite integral as area under a curve; and
applications to displacement, velocity and acceleration.

The syllabus also marks some exclusions, such as the general solution of trigonometric equations, problems involving two circles and the area between two curves.

The strands connect. AO2 asks students to make and use connections across topics.

What the Examiners Are Looking For

The syllabus lists three assessment objectives, with approximate weightings.

AO1: Use and Apply Standard Techniques (35%)

Recall facts, terminology and notation, read information from tables, graphs, diagrams and texts, and carry out routine procedures.

AO2: Solve Problems in a Variety of Contexts (50%)

Choose the right concept, rule or formula, translate information between forms, connect topics, set problems up in mathematical terms and interpret results in context.

AO3: Reason and Communicate Mathematically (15%)

Justify statements, explain answers in context, and write mathematical arguments and proofs.

Half the weighting sits on problem-solving.

Fluent technique is needed, but it is not enough on its own.

How to Read the Syllabus Document

The document follows a clear order. Read it in that order once.

Introduction: what the syllabus prepares students for, the three strands and the G3 Mathematics assumption
Aims: the purpose of the subject, in four points
Assessment Objectives: AO1 to AO3 and their approximate weightings
Scheme of Assessment: the two papers, timings, marks and notes on working, formulae, accuracy and units
Use of Calculators: a single line on approved calculators
Subject Content: the ten topics by strand, including what is excluded
Mathematical Formulae: the formulae listed for candidates, so you can see what is given and what must be learnt
Mathematical Notation: the symbols used in Cambridge mathematics papers

Common Misunderstandings

“G3 Mathematics topics no longer matter.”

The syllabus assumes G3 Mathematics knowledge. It is not tested directly, but it may be required inside other questions, and some properties used in plane geometry proofs are marked as learnt in G3 Mathematics.

“Paper 1 and Paper 2 test different topics.”

The syllabus does not assign topics to a particular paper. The two papers share the same time, marks and weighting, and differ in the number of questions and the maximum marks per question.

“Only the final answer counts.”

The syllabus states that omitting essential working loses marks. AO3 also rewards justification, explanation and proof.

“Every formula will be given.”

The formula list covers the quadratic formula, the binomial expansion, trigonometric identities and triangle formulae. It has no formulae for logarithms, differentiation or integration.

How Students Can Use the Syllabus

1. Make a topic checklist

List the ten topics, A1 to A6, G1 to G3 and C1, and rate your confidence in each one.

2. Mark the exclusions

Note what is left out, so revision time goes to what is examined.

3. Know the formula list

Practise with the formulae that are given, and learn the rest thoroughly.

4. Write full working

Show each essential step, even when you can do it in your head.

5. Practise to time

Work through full papers in 2 hours 15 minutes each.

6. Sort your mistakes by objective

Ask whether an error was about technique, problem-solving or reasoning, then practise that.

How Parents Can Help

download the syllabus and keep a copy at home;
ask to see the topic checklist once in a while;
check that revision covers all three strands, not only the favourite ones;
make sure your child practises with the calculator they will use in the examination;
encourage full working, even when the answer is right; and
keep conversations about Additional Mathematics calm and specific.

How eduKateSG Uses the Additional Mathematics Syllabus

we map lessons to the K341 topic list, strand by strand;
we check G3 Mathematics foundations, since the syllabus assumes them;
we teach clear, complete working, because essential working carries marks;
we use the assessment objectives to see whether a mistake is about technique, problem-solving or reasoning; and
we practise under the timing of the two papers.

How many papers are there in SEC G3 Additional Mathematics?

There are two written papers. Each lasts 2 hours 15 minutes, carries 90 marks and is worth 50% of the total.

Is a calculator allowed in K341?

Yes. The syllabus states that an approved calculator may be used in both Paper 1 and Paper 2.

Are formulae given in the examination?

Yes. The syllabus states that relevant mathematical formulae will be provided, and the formula list is printed in the syllabus document. It does not include formulae for logarithms, differentiation or integration.

Is K341 the same as the earlier Additional Mathematics syllabus 4049?

The SEAB listing page shows 4049 as the subject code for reference for 2026 and earlier. The K341 document itself does not describe any changes, so check the 2027 PDF directly rather than relying on older notes.

Does my child need G3 Mathematics for Additional Mathematics?

The syllabus assumes knowledge of G3 Mathematics. That content is not tested directly, but it may be needed in questions on other topics.

Where do I download the K341 syllabus?

It is on the SEAB page for 2027 SEC G3 syllabuses. Check that you are using the latest version.
