What is the Format of GCE O levels Additional Mathematics?


Additional Mathematics is a subject that extends and enhances the concepts taught in ordinary mathematics. It provides students with a deeper understanding of mathematical principles and their applications. In this article, we will explore the format of Additional Mathematics, including the assessment objectives, scheme of assessment, and subject content.

Assessment Objectives: The assessment for Additional Mathematics aims to test candidates’ abilities in three key areas:

  1. AO1: Use and apply standard techniques (35% weighting)
    • Recall and utilize facts, terminology, and notation.
    • Extract information from various sources such as tables, graphs, diagrams, and texts.
    • Perform routine mathematical procedures.
  2. AO2: Solve problems in a variety of contexts (50% weighting)
    • Interpret information to identify relevant mathematical concepts, rules, or formulas.
    • Translate information from one form to another.
    • Make connections across topics and subtopics.
    • Formulate problems into mathematical terms.
    • Analyze and select appropriate mathematical techniques to solve problems.
    • Interpret results within the given problem’s context.
  3. AO3: Reason and communicate mathematically (15% weighting)
    • Justify mathematical statements.
    • Provide explanations within the context of a given problem.
    • Write mathematical arguments and proofs.

Scheme of Assessment: The assessment for Additional Mathematics consists of two papers, namely Paper 1 and Paper 2. Here are the details:

  • Paper 1:
    • Duration: 2 hours 15 minutes
    • Description: Contains 12-14 questions of varying marks and lengths, with up to 10 marks per question.
    • Candidates are required to answer ALL questions.
    • Marks: 90
    • Weighting: 50%
  • Paper 2:
    • Duration: 2 hours 15 minutes
    • Description: Contains 9-11 questions of varying marks and lengths, with up to 12 marks per question.
    • Candidates are required to answer ALL questions.
    • Marks: 90
    • Weighting: 50%


  • Omission of essential working will result in mark deductions.
  • Relevant mathematical formulae will be provided.
  • Answers should be given to an appropriate level of accuracy as specified in the question.
  • SI units should be used for questions involving mass and measures.
  • Both the 12-hour and 24-hour clock may be used for quoting times of the day.
  • Compound units should be expressed using the solidus notation (e.g., 5 m/s for 5 meters per second).
  • Unless specified, the value of π should be taken as 3.142 or π = 3.142.
  • Each question paper provides space for working and answers.

Subject Content: The syllabus for Additional Mathematics covers various topics and subtopics. Here are some of the key areas:

  1. Algebra:
    • Quadratic functions
    • Equations and inequalities
    • Surds
    • Polynomials and partial fractions
    • Binomial expansions
    • Exponential and logarithmic functions
  2. Geometry and Trigonometry:
    • Trigonometric functions, identities, and equations
    • Coordinate geometry in two dimensions
    • Proofs in plane geometry
  3. Calculus:
    • Differentiation and integration
    • Applications of derivatives and integrals


Additional Mathematics follows a comprehensive format that assesses students’ abilities to apply standard techniques, solve problems, and reason mathematically. The subject covers various topics, including algebra, geometry, trigonometry, and calculus, providing students with a solid foundation in advanced mathematical concepts. By understanding the format and content of Additional Mathematics, students can prepare effectively and excel in their examinations.
