Day 4
Exam
A four-hour Two-Part examination where:
- Part 1 of the examination comprises a number of Multiple-Choice questions (where only one answer is correct) and Multiple-Response questions (where, at most only two correct answers are possible). – The scoring for the Multiple Choice is one mark for a correct answer and no marks for an incorrect answer. – The scoring for the Multiple-Response questions is one mark for a correct answer and two marks are available for the two possible correct answers
- Part 2 contains 10 multiple-part questions. Three marks per question are available for a correct answer
Certificate No.
