## Introduction:

The General Certificate of Education (GCE) O Levels Additional Mathematics is an academic qualification offered to students in many countries, including Singapore and the United Kingdom. It is designed to provide students with a strong foundation in advanced mathematical concepts and problem-solving skills. In this article, we will explore the format of the GCE O Levels Additional Mathematics examination based on the provided syllabus and assessment objectives.

## Assessment Objectives:

The assessment objectives for GCE O Levels Additional Mathematics are divided into three categories:

AO1: Use and apply standard techniques

- Recall and use facts, terminology, and notation.
- Read and use information from tables, graphs, diagrams, and texts.
- Carry out routine mathematical procedures.

AO2: Solve problems in a variety of contexts

- Interpret information to identify relevant mathematical concepts, rules, or formulas.
- Translate information from one form to another.
- Make connections across topics/subtopics.
- Formulate problems into mathematical terms.
- Analyze and select relevant information to solve problems.
- Interpret results in the context of a given problem.

AO3: Reason and communicate mathematically

- Justify mathematical statements.
- Provide explanations in the context of a given problem.
- Write mathematical arguments and proofs.

Weightage of Assessment Objectives: The approximate weightings for the assessment objectives are as follows:

- AO1: 35%
- AO2: 50%
- AO3: 15%

Scheme of Assessment: The GCE O Levels Additional Mathematics examination consists of two papers: Paper 1 and Paper 2. The duration for each paper is 2 hours and 15 minutes. Both papers require candidates to answer all the questions.

Paper 1:

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

Additional Information:

- Omission of essential working will result in a loss of marks.
- Relevant mathematical formulae will be provided for candidates.
- Non-exact numerical answers should be correct to 3 significant figures or 1 decimal place for angles in degrees, unless specified otherwise.
- SI units will be used for questions involving mass and measures.
- The 12-hour and 24-hour clock may be used for quoting times of the day.
- The solidus notation (e.g., 5 m/s) should be used for expressing compound units.
- Unless specified, the value of π or π = 3.142 should be used.
- Spaces will be provided in each question paper for working and answers.
