ISC Class 12 Computer Science Syllabus
The CISCE will administer the Class 10 ICSE board examination (Council for the Indian School Certificate Examination). The ICSE board’s syllabus gives students practical information in every subject to improve their analytical skills. The ISC Computer Science Syllabus design pushes students to go beyond their textbooks, laboratory classes provide firsthand knowledge and understanding of the textual concepts taught in the classroom rather than simply memorising them.
Studying Computer Applications is a significant subject since it has many logical and functional components required to get good results. Students will need adequate guidance and support to prepare for this subject. Extramarks is one of the leading educational platforms that provides handson training material in the form of ISC Class 12 Computer Science Syllabus.
The best training material is available on the Extramarks platform for the ISC Class 12 Computer Science Syllabus. It provides an overview of the entire syllabus to the students so that they can plan and prepare in advance to complete their syllabus.

ISC Class 12 Computer Science Syllabus Paper pattern
Before students begin their exam preparation, they must familiarise themselves with ISC Class 12 Computer Science Syllabus, the marking scale, and the paper format. Extramarks provides the complete exam paper pattern of Computer Science for the academic year 20232024. Students can get a thorough understanding of the subject’s fundamental concepts with the help of the ISC Class 12 Computer Science Syllabus.
As per the recent upgrade in ISC Class 12 Computer Science Syllabus, the Computer Applications paper carries a total of 100 marks. There are two papers: Theory and Practical. Students are evaluated based on their overall performance on both exams..
According to ISC Class 12 Computer Science Syllabus, this examination consists of two papers: Paper I: Theory of 3 hours, 70 marks. PaperII is 30 marks, a 3hour practical exam. Two sections of Paper I. Compulsory short answer questions covering the whole syllabus are included in Part I, which carries a total of 20 marks.
Part II (50 marks) is divided into three Sections A, B, and C. Students must answer two out of three questions in all the three sections A, B and C. In each Section A and B carry 10 marks whereas Section C only has 5 marks. So, Part II there are a total of six questions that students need to answer.
The practical exam consists of 30 marks. This paper will be evaluated by a visiting examiner who has been appointed locally by the council. Candidates must attempt any one of the three programming problems during this exam.

ISC Computer Science Class 12 Syllabus
There are two papers in the subject: Paper I is Theory of 3 hours and 70 marks. Paper II is Practical of 3 hours and 30 marks. Paper I is divided into two parts. Part I (20 marks) consists of compulsory short answer questions, testing knowledge, application and skills relating to the entire syllabus.
Part II (50 marks) is divided into three Sections, A, B and C. You are required to answer two questions out of three from Section A (each carrying 10 marks) and two questions out of three from Section B (each carrying 10 marks) and two questions out of three from Section C (each carrying 5 marks). Therefore, a total of six questions are to be answered in Part II.
Section A
1. Boolean Algebra
(a) Propositional logic, well formed formulae, truth values and interpretation of well formed formulae (wff), truth tables, satisfiable, unsatisfiable and valid formulae. Equivalence laws and their use in simplifying wffs.
(b) Binary valued quantities; basic postulates of Boolean algebra; operations AND, OR and NOT; truth tables.
(c) Basic theorems of Boolean algebra (e.g. duality, idempotence, commutativity, associativity, distributivity, operations with 0 and 1, complements, absorption, involution); De Morgan’s theorem and its applications; reducing Boolean expressions to sum of products and product of sums forms; Karnaugh maps (up to four variables).

(b) Applications of Boolean algebra and logic gates to half adders, full adders, encoders, decoders, multiplexers, NAND, NOR as universal gates.
Section B
The programming element in the syllabus (Sections B and C) is aimed at algorithmic problem solving and not merely rote learning of Java syntax. The Java version used should be 5.0 or later.
For programming, the students can use any text editor and the javac and java programs or any other development environment: for example, BlueJ, Eclipse, NetBeans etc. BlueJ is strongly recommended for its simplicity, ease of use and because it is very well suited for an ‘objects first’ approach.
3. Implementation of algorithms to solve problems
The students are required to do lab assignments in the computer lab concurrently with the lectures. Programming assignments should be done such that each major topic is covered in at least one assignment. Assignment problems should be designed so that they are sufficiently challenging. Students must do algorithm design, address correctness issues, implement and execute the algorithm in Java and debug where necessary.
4. Programming in Java
(Review of Class XI Sections B and C)
Items 4 to 13 should be introduced almost simultaneously along with classes and their definitions. While reviewing, ensure that new higher order problems are solved using these constructs.

(b) Analysis of some realworld programming examples in terms of objects and classes.

FAQs (Frequently Asked Questions)
1. What criteria does the visiting examiner use to assess the practical exam?
The candidate’s choice of algorithm and implementation technique, documentation, and proper output on known inputs listed in the question paper all factor towards how well the candidate does on the programming task they were given. Programming assignments are of 5 marks completed during the year, and the computer programming problem answer carries 15 marks. The final 10 points are for internal assessment.
2. What should the preparation strategy for ISC Class 12 Computer Science Board exam be?
Creating a schedule is one of the most important aspects of preparing for the final exam. You can cover all the chapters and subjects. Analyse your performance by answering questions from previous years’ exams. Do not unnecessarily stress yourself; instead, take a break from studying to relax and rejuvenate with friends and family members. Keep your confidence level high by following your study schedule and leave nothing until the last minute except revision. Students will find it easier to crack the tests, and won’t be anxious or stressed before the exams.
