Auto Electrical Work WAEC Syllabus

Below is the WAEC Syllabus for this year; kindly make judicious use of it.

  1. PREAMBLE

This examination syllabus has been evolved from the Senior Secondary School Trade Curriculum. The examination syllabus does not replace the curriculum.
The syllabus has been arranged to subsume six themes: battery, starting, ignition, charging, lighting and auxiliary systems.
  1. OBJECTIVE

The objective of the syllabus is to test candidates’ knowledge, skills and attitude in the field of Auto Electrical Works. Specifically, candidates are to:
  • understand the concepts in auto electrical works;
  • use tools and equipment to carry out maintenance and repair on motor vehicles;
  • understand the safety practices and observe them in the work environment.
  1. EXAMINATION SCHEME

There will be three papers, Papers 1, 2 and 3, all of which are to be taken. Papers 1 and 2 shall be a composite paper to be taken at one sitting.
PAPER 1:      will consist of forty multiple-choice objective questions all of which are to be answered in 45 minutes for 40 marks.
PAPER 2:      will consist of six short-structured questions. Candidates will be required   to answer any four in 1 hour for 60 marks.
PAPER 3:      will be a practical test of 2 hours duration. It will consist of three skill-based questions out of which candidates will answer two for 90 marks.
A list of materials for the test shall be made available to schools not less than two weeks before the paper is taken for materials procurement and relevant preparations.
Alternative to Practical Test:
Alternatively, in the event that materials for the actual practical test cannot be acquired, the Council may consider testing theoretically, candidates’ level of acquisition of the practical skills prescribed in the syllabus. For this alternative test, there will be two compulsory essay questions to be answered in 2 hours for 100 marks.
Industrial Attachment
This should be done by the candidates during the long vacation between their SS II and SS III course. It will be supervised and assessed by their subject teachers. It will carry 10 marks.
