WAEC Syllabus for Basic Electronics 2022/2023

The WAEC syllabus for Basic Electronics is the topic you must study to sit for the examination. It contains the aims and objectives, notes and format for the Basic Electronics exam.

Studying the Basic Electronics syllabus is necessary for your exam preparation. It will serve as a guide for you to know the topics to read. There are also notes on concepts you should pay attention to learning.

Exam preparations without using the Basic Electronics syllabus are like going to the farm without your agricultural tools. You will end up not being productive.

Ensure you begin your exam preparations using the syllabus.

This post contains the Basic Electronics syllabus and recommended textbooks of the West African Examination Council (WAEC).

WAEC Basic Electronics

The syllabus is intended to equip candidates with a broad understanding of the technology of manufacturing, maintenance and repair of domestic and industrial equipment.

It will also offer candidates sufficient knowledge and skills to form a valuable foundation for an electronics-related vocation or pursue further educational qualifications.

Candidates will be expected to cover all the topics.

Objectives

The objective of the syllabus is to test candidates’

  • knowledge and understanding of the basic concepts and principles of electronics;
  • ability to use simple electronic devices to build and  test simple electronic systems;
  • problem-solving skills through the use of the design  process;
  • preparedness for further work in electronics;
  • knowledge in entrepreneurial skills and work ethics.

Scheme of Examination

There will be three papers, Papers 1, 2 and 3, all of which must be taken. Papers 1 and 2 shall be composite papers to be taken in one sitting.

PAPER 1: Will consist of fifty multiple-choice objective questions all of which are to be answered in 1 hour for 50 marks.

PAPER 2: will consist of seven short-structured questions. Candidates will be required to answer any five in 1 hour for 50 marks.

PAPER 3: This will be a practical paper on two experiments both of which are to be carried out by candidates in 3 hours for 100 marks.

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 questions to be answered within 2 hours for 100 marks.
