 SCHEME OF EXAMINATION

 

There will be three papers, Papers 1, 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.

 

Paper 2:               will consist of five questions out of which candidates will be required to answer any four in 1½ hours for 60 marks.

 

Paper 3:               will be practical test of 3 hours, 10 minutes duration.  It will consist of one compulsory question for 100 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 material procurement and relevant preparations.

 

 ALTERNATIVE TO PRACTICAL TEST

 

The Council may consider testing candidates’ ability in practical work as prescribed in the syllabus in the event that materials for the actual practical test cannot be acquired.  For this alternative test there will be one question to be answered in 3 hours for 100 marks
