Second Paper
Nine questions to be set. Five questions to be answered. Short answer type questions are recommended. There may be several parts in a question and different units may be mixed in questions. While setting questions the entire syllabus may be covered as far as practicable. Two questions to be answered from group 'A' and three questions to be answered from group 'B'
