will be given. A number as the answer should be entered using the virtual keyboard on the monitor. 
	
2. Questions Q.1 – Q.25 carry 1mark each. Questions Q.26 – Q.55 carry 2marks each. The 2marks 
questions include two pairs of common data questions and two pairs of linked answer questions. The 
answer to the second question of the linked answer questions depends on the answer to the first 
question of the pair. If the first question in the linked pair is wrongly answered or is not attempted, 
then the answer to the second question in the pair will not be evaluated.

will result in NEGATIVE marks.  For all 1 mark questions, ? mark will be deducted for each wrong 
answer. For all 2 marks questions, ? mark will be deducted for each wrong answer.  However, in the 
case of the linked answer question pair, there will be negative marks only for wrong answer to the 
first question and no negative marks for wrong answer to the second question. There is no negative 
marking for questions of numerical answer type.
