Chapter-wise CBSE Class 12 Computer Science Deleted Syllabus 2023-24

When preparing for the board exams, students must notice the syllabus reduced by the CBSE Board. For Class 12 Computer Science, students will not have to study web scripting, payment apps, database management. Check the details below according to the chapters.

Chapter - Computational Thinking and Programming 

  • Recursion – simple algorithms with recursion: print a message forever, the sum of first n natural numbers, factorial, Fibonacci numbers, recursion on arrays: binary search
  • Idea of efficiency: performance measurement in terms of the number of operations
  • Data structures: Lists as covered in Class XI, Stacks – Push, Pop using a list, Queues – Insert, Delete using a list. (One of the data structures is Stack or Queue. While setting the question paper a student will have an option between Stack and Queue.)

Chapter - Computer Networks

  • Web Scripting Client side (VB Script, Java Script, PHP) and Server side (ASP, JSP, PHP), Web 2.0 (for social networking)
  • E-commerce payment transactions using online banking, mobile banking, payment apps, and services

Chapter - Database Management

Create table, drop table, alter table, update,.set, insert, delete.
