Studying the Technical Drawing 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.
Ensure you begin your exam preparations using the syllabus.
This post contains the Technical Drawing and recommended textbooks of the West African Examination Council (WAEC).
WAEC Technical Drawing
SCHEME OF EXAMINATION
There will be three papers, Papers1, 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 forty multiple-choice objective questions all of which are to be answered in 1 hour for 40 marks. The paper will consist of two sections, Sections A and B as follows:
Section A will consist of thirty questions drawn from the general principles, techniques and uses of plane and solid geometry.
Section B will consist of ten questions in each of two alternative parts: Part I (Building Drawing) and Part II (Mechanical Drawing). Candidates will be required to answer questions in one part only.
PAPER 2: will consist of five essay questions on plane, solid and vector geometry. Candidates will be required to answer any three of the questions in1¾ hours for 60 marks.
PAPER 3: will consist of two sections, Sections A and B to be taken in 2¾ hours for 100 marks.
Section A will consist of three questions requiring sketches of objects, components, symbols and tools used in the Building and Mechanical industries. One of the questions will be compulsory.
Candidates will be required to answer the compulsory question for 20 marks and one of the other questions for 10 marks. The section will require 45 minutes.
Section B will consist of two questions: one on Building Drawing and the other, on Mechanical Drawing. Candidates will be required to answer only one of the questions in 2 hours for 70 marks.
