  • Hollywood/Hangman: A word guessing game
  • Cows ‘N Bulls: A word/number Guessing game
  • Random Number Guessing Game (High\Low)
  • A game to check whether a word does not use any of the forbidden letters
  • Cross‘N knots game: A regular tic-tac –toe game.ORSimilar projects may be undertaken in other domains. (As mentioned in general guidelines for project, given at the end of the curriculum in a group of 2-4 students)

* Collaboration and Presentation of the project

3. Practical File 5+1*

  1. Record of the configuration of computer system used by the student in the computer lab (by exploring inside computer system in the first 2 lab classes).
  2. Must have minimum 20 programs from the topics covered in class XI course.
