The ISC Class 12 Computer Science Syllabus for 2025-2026 covers programming, data structures, and algorithms. It includes a 70-mark theory exam and a 30-mark practical exam, aiming to develop problem-solving and coding skills for future studies in computer science.
Stay tuned for more updates and resources!
ISC COMPUTER SCIENCE SYLLABUS FOR CLASS 12
There will be two papers in Computer Science. Paper I Theory and Paper II Practical consisting of 3 hours each.
Paper I: Theory (70 marks)
Paper II: Practical (30 marks)
This paper of three hours duration will be evaluated by the Visiting Examiner appointed locally and approved by CISCE.
The paper shall consist of three programming problems from which a candidate has to attempt any one. The practical consists of two parts:
1. Planning Session
2. Examination Session
The total time to be spent on the Planning session and the Examination session is three hours. A maximum of 90 minutes is permitted for the Planning session and 90 minutes for the Examination session.
Candidates are to be permitted to proceed to the Examination Session only after the 90 minutes of the Planning Session are over.
The candidates will be required to prepare an algorithm and a hand written Java program to solve the problem.
The program handed in at the end of the Planning session shall be returned to the candidates. The candidates will be required to key-in and execute the Java program on seen and unseen inputs individually on the Computer and show execution to the Visiting Examiner. A printout of the program listing including output results should be attached to the answer script containing the algorithm and handwritten program. This should be returned to the examiner. The program should be sufficiently documented so that the algorithm, representation and development process is clear from reading the program. Large differences between the planned program and the printout will result in loss of marks. Teachers should maintain a record of all the assignments done as part of the practical work through the year and give it due credit at the time of cumulative evaluation at the end of the year. Students are expected to do a minimum of twenty-five assignments for the year.
Marks (out of a total of 30) should be distributed as given below:
Candidates will be required to submit a work file containing the practical work related to programming assignments done during the year.
Marks should be given for choice of algorithm and implementation strategy, documentation, correct output on known inputs mentioned in the question paper, and correct output for unknown inputs available only to the examiner.
NOTE:
Algorithm should be expressed clearly using any standard scheme such as a pseudo code.
• Any suitable Operating System can be used.
• JDK 6 or later.
• Documentation for the JDK version being used.
• A suitable text editor. A development environment with a debugger is preferred (e.g. BlueJ, Eclipse, NetBeans). BlueJ is recommended for its ease of use and simplicity.
Students who are enrolled in the ISC Class 12 2024-25 Academic session and have opted for computer Science are advised to go through the syllabus provided above in the form of a PDF and read it carefully. There has been slight modification in the syllabus so make sure you have the latest updated ISC Computer Science Syllabus Class 12 before you start preparing for the board exam.
