Revised Computer Science Syllabus 2024-25 for CBSE Class 12

In the revised syllabus for CBSE class 12 computer science 2024-25, the following topics have been removed from the syllabus of 2024-25:

Unit Number	Name of Unit	Topic Name
Unit I	Computational Thinking and Programming	Recursion Idea of efficiency Data-structures
Unit II	Computer Networks	Web Scripting Client-side Payment purchases via e-commerce using online banking, mobile banking, payment applications, and services.
Unit III	Database Management	CREATE TABLE DROP TABLE ALTER TABLE UPDATE SET INSERT DELETE

Class 12, the final, culminating year of a student’s school life, is the most rigorous year that there is. From the beginning of the year, the first thing we hear every day throughout class 12 is that we have our exams coming soon - first the midterms, then the final exams with the full syllabus, then the two sets of pre-boards, and then finally our board exams. It seems as though the exams never end once we reach Class 12 until we graduate and leave school to move on to college.

Understanding this, and especially understanding the rigour that Class 12 Computer Science students go through, Vedantu has put together the syllabus of Computer Science Class 12 on this page. This is alongside several other syllabi for other subjects, too, which can be found easily on the Vedantu website using a simple search. This has been done in the hopes that students will find the presence of the syllabus helpful and useful in their process of studying.

Syllabus of Computer Science Class 12

It is important to remember your concepts from Class 11 Computer Science well when diving into your Class 12 Computer Science Syllabus. This is because Class 11 Computer Science acts as a way for students to develop a base in the subject, and in Class 12, this base is built upon or carried forward.

The Following is What the Computer Science Syllabus for Class 12 CBSE looks like:

Unit 1: Programming and Computational Thinking - 2 (PCT-2)	Revising Python Functions File handling Using Python libraries Recursion Idea of efficiency Data visualisation using Pyplot Data structures
Unit 2: Computer Networks (CN)	Structure of a network Network devices Network stack IP addresses TCP Protocols Basic network tools Application layer
Unit 3: Data Management-2 (DM-2)	Writing a minimal Django based web application Interface Python with an SQL database SQL commands
Unit 4: Practical Component	Programming in Python Data Management in SQL and web-servers Project work (coding)
