WAEC Radio, Television and Electronics Works
This examination syllabus evolved from the Senior Secondary School curriculum for Trade Subjects.
It is intended to give candidates insight into the world of Radio, Television and Electronics Works; improve their attitude towards the maintenance and repairs of radio, television and electronic equipment and enable them to appreciate the relationship between science and technology.
The objective of the syllabus is to test the candidates’ knowledge and understanding of the following:
- Workshop Safety Rules and Regulations;
- Basic Electricity;
- Electronic Tools and Instruments;
- Electronic Devices and Circuits;
- Electronic Communication Systems;
- Workshop Practice and Maintenance;
- Entrepreneurship in Radio, Television and Electronics Works.
There will be three papers, Papers 1, 2 and 3, all of which must 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 hour 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 Work
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 questions to be answered in 2 hours for 100 marks.
This should be done by the candidates during the long vacation between their SS II and III course. It will be supervised and assessed by their subject teachers. It will carry 10 marks.
