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.
2. 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:
(i) understand the concepts in auto electrical works;
(ii) use tools and equipment to carry out maintenance and repair on motor vehicles;
(iii) understand the safety practices and observe them in the work environment.
There will be three papers, Papers 1, 2 and 3, all of which are to be taken. Papers 1 and 2 shall be composite paper to be taken at one sitting.
PAPER 1: will consist of forty multiple-choice objective questions, all which are to be answered in 45 minutes for 40 marks.
PAPER 2: will consist of six structured short-answer questions. Candidates will be required to answer any four of them in 1 hour for 60 marks.
PAPER 3: will be a practical test of 2 hour duration. It will consist of three skill-based questions out of which candidates will be required to answer two for 100 marks.
A list of materials for the test shall be made available to schools not less than two weeks
1
before the taking of the paper for procurement and relevant preparation for the test to be made.
Alternatively, the Council may consider testing candidates’ familiarity with the practical work prescribed in their syllabus in the event that the materials for the actual practical test cannot be acquired. For this test, two compulsory essay questions will be set. Candidates will be given 2 hours to answer them for 100 marks.
2
This should be done by the candidates during the long vacation between their SS II and SS III courses. It will be supervised and assessed by their subject teachers. It will carry
10 marks.
