WAEC syllabus 90/WAEC-Technical-Drawing
WAEC Technical Drawing

SCHEME OF EXAMINATION

The examination shall consist of three papers, Papers1, 2 and 3; all of which must be taken. Papers 1 and 2 shall composite and shall be taken at one sitting.

Paper 1: This shall consist of forty compulsory multiple choice objective questions for 40 marks and will last for 1 hour. The paper will be in two sections, Sections A and B.

Section A will contain Questions1 to 30 and will be on the general principles, techniques and uses of plane and solid geometry aspects of the syllabus.

Section B will be in two parts, Part I on Building Drawing and Part II on

Mechanical Drawing. Each part will contain ten questions, Questions 31 to 40.

Candidates may answer questions in one part only.

Paper 2: This shall consist of five essay questions on plane, solid and vector geometry out of which candidates shall be required to answer three questions only within 1¾ hours for 60 marks.

Paper 3: This shall consist of two sections, Sections A and B which will last for 2¾ hours and carry 100 marks.

Section A shall consist of a compulsory question and others requiring sketches of objects, components, symbols and tools used in the Building and Mechanical industries. Candidates shall be required to answer the compulsory question for 20 marks and one of the other questions for 10 marks, making a total of 30 marks. The section will last for 45 minutes.

Section B shall consist of two questions, one on Building Drawing and the other on Mechanical Drawing. Candidates will be required to answer either of the two questions in 2 hours for 70 marks.
