during the course and to serve as a record of competence.
1.2 A group of two/three students a steam may be allowed to work on one project.

2. Project content
2.1 Project for Class-XI can be selected from one of the topics given in event
programming.
2.2 Project for Class-XII should ensure the coverage of following areas of
curriculum:
a. Problem Solving
b. Data Structure
c. Programming in Python
d. Data File Handling
Theme of the project can be
· Any subsystem of a System Software or Tool
· Any Scientific or a fairly complex algorithmic situation
· Business oriented problems like Banking, Library in formation system.
Hotel or Hospital management system, Transport query system
· Quizzes/Games;
· Tutor/Computer Aided Learning Systems
2.3 The aim of the project is to highlight the abilities of algorithmic formulation,
modular programming, optimized code preparation, systematic documentation
and other associated aspects of Software Development.
