A5-R3: STRUCTURED SYSTEM ANALYSIS AND DESIGN

NOTE:
1. There are 2 PARTS in this Module/paper. PART 1 contains 4 ques. and PART 2 contains 4 ques..

2. PART 1 is to be answered in the TEAR-OFFANSWER SHEET only, attached to the ques. paper, as per the instructions contained therein. PART 1 is NOT to be answered in the ans book.

3. Maximum time allotted for PART 1 is 1 HOUR. ans book for PART 2 will be supplied at the table when the ans sheet for PART 1 is returned. However, candidates who complete PART 1 earlier than 1 hour, can collect the ans book for PART 2 immediately after handing over the ans sheet for PART ONE.
TOTAL TIME: three HOURS TOTAL MARKS: 100
(PART ONE-40; PART 2 – 60)

PART ONE
