PAPER 3: will be a practical test of 2 hour duration. It will consist of three skill-based questions out of which candidates will answer two for 90 marks.
A list of materials for the test shall be made available to schools not less than two weeks before the paper is taken for materials procurement and relevant preparations.
Alternative to Practical Work:
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 compulsory questions to be answered in 2 hours for 100 marks.
Industrial Attachment:
This should be done by the candidates during the long vacation between their SS II and SS III course. It will be supervised and assessed by their subject teachers. It will carry 10 marks.
