Welcome to the official WAEC Syllabus for Auto Mechanical Work.This syllabus is drawn purposely for examination, hence the topics are not necessarily arranged in the order in which they should be taught.
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 two sections, Sections A and B to be answered in 2 hours 15 minutes for 80 marks.
Section A: will consist of ten short-structured questions to be answered in
30 minutes for 20 marks.
Section B: will consist of five essay questions. Candidates will be
required to answer any four in 1 hour 45 minutes for 60 marks.
Paper 3: will be a practical test of 2 hours 30 minutes duration. It will consist of
two compulsory questions for 80 marks.
A list of materials shall be made available to schools not less than two weeks before the paper is taken for material procurement and relevant preparation.
(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 sets of compulsory questions to be answered in 1½ hours for 80 marks.
