WAEC Basic Electricity/Electronics Examination Scheme
EXAMINATION SCHEME There will be three papers, Papers 1, 2 and 3 all of which must be taken. Papers 1 and 2 will be a composite paper to be taken at one sitting.
PAPER 1 will consist of fifty multiple-choice objective questions to be answered in 1 hour for 50 marks.
PAPER 2 will consist of three sections: Sections A, B and C as follows:
Section A will be compulsory for all candidates. It will consist of four questions out of which candidates will be required to answer any three.
Section B will be for candidates in Ghana only. It will consist of three questions out of which candidates will be required to answer two.
Section C will be for candidates in Nigeria, Sierra Leone and The Gambia only. It will also consist of three questions out of which candidates will be required to answer two. Thus, candidates will be required to answer five questions in all. The paper will last 1 hour and carry 50 marks.
PAPER 3 will be a practical paper of two experiments both of which are to be carried out by candidates in 3 hours for 100 marks.
