WAEC Syllabus for Metal Work 2023/2024

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

Studying the Metal Work subject 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 Metal Work 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 Metal Work and recommended textbooks of the West African Examination Council (WAEC).

WAEC Metal Work

PREAMBLE

The examination is designed to test candidate’s skills in basic design, practical work and entrepreneurship.

It will also assess their knowledge of tools, equipment and materials and understanding of those areas of creative thinking which can be expressed and developed through planning and working primarily on metals as part of general education.

The test will also assess candidate’s competency in the fundamentals of manufacturing to pursue higher education in science and technology.

AIM

The aim of the syllabus is to test candidates’ acquisition of the requisite knowledge and skills needed to pursue further education and self-development in science and technology.

OBJECTIVES

Candidates will be expected to

  • observe safe working practices in the workshop;
  • demonstrate knowledge and understanding of tools, materials and equipment;
  • apply basic processes for the care and maintenance of hand and machine tools;
  • have the ability in identifying, analysing and evaluating a problem;
  • apply their knowledge of processes and materials to the solution of problems;
  • demonstrate basic skills of good craftsmanship;
  • apply knowledge of career opportunities in metalwork;
  • have the ability to translate an idea into a project design.

SCHEME OF EXAMINATION

The examination shall consist of three papers, Papers 1, 2 and 3, all of which must be taken. Papers 1 and 2 will be composite paper to be taken at one sitting.

Paper 1:  Will consist of forty compulsory multiple choice objective questions.  Candidates will be allowed 1 hour to answer the questions.  The paper will carry 40 marks.

Paper 2: Will consist of five questions out of which candidates will be expected to answer  four  in 1½ hours.  The paper will carry 60 marks.  All questions will carry equal marks.

Paper 3: Will be a practical test of 3 hours.  10 minutes shall be given prior to the commencement of the examination for the study of the drawings.  

The paper will consist of two questions out of which candidates will be expected to answer one.

They will be required to make a test piece for which the appropriate drawings will be supplied. The paper will carry 100 marks. Schools will be required to supply materials that will be needed for the practical test.
