In this blog post, we will explore the aims and objectives of the Dyeing and Bleaching syllabus, the exam format, and the topics you should focus on.
Objectives
The Dyeing and Bleaching examination aims to assess candidates’ knowledge and practical skills in working with dyes and chemicals on fabrics.
It also evaluates their creative abilities in visual representation and their capacity to produce finished fabric designs for economic value.
Furthermore, the exam emphasizes candidates’ understanding of safety measures involved in dyeing and bleaching processes.
Scheme of Examination
The Dyeing and Bleaching examination consists of three papers:
Papers 1, 2, and 3. Candidates are required to take all three papers. Papers 1 and 2 are combined into a composite paper, which should be completed within 45 minutes.
Paper 1 includes forty multiple-choice questions from the entire syllabus, totaling 40 marks.
Paper 2 comprises six essay-type questions, out of which candidates must answer any four, with a time limit of 1 hour and 40 minutes and a total of 60 marks.
Paper 3 evaluates candidates’ practical skills in tie-dye, batik, and printing.
It offers three alternatives
Tie-dye, Batik (Wax or Starch Resist), and Printing.
Candidates must choose and answer the questions corresponding to their chosen alternative.
Each alternative carries 100 marks, and candidates have 30 minutes for preparation, followed by a four-hour test conducted and assessed by a visiting Examiner appointed by WAEC.
