ISC Class 12 Syllabus 2026-27

The ISC (Indian School Certificate) Class 12 syllabus for the academic session 2026-27 is prescribed by the Council for the Indian School Certificate Examinations (CISCE). The ISC is one of India's most respected senior secondary examinations, recognised by universities and professional institutions across the country and internationally. The curriculum spans a broad range of arts, science, commerce, and vocational streams, enabling students to build deep subject expertise in their chosen fields while maintaining a strong foundation in English communication.

Students in ISC Class 12 typically study five or six subjects, with English being compulsory for all candidates. The remaining subjects are chosen from three groups covering languages, sciences, and humanities or commerce disciplines. Examinations are conducted annually in February and March for all registered ISC schools across India.

This page provides a complete overview of the ISC Class 12 syllabus for 2026-27, including a subject-wise list with direct links to individual detailed syllabus pages, the full group structure, exam pattern, marking scheme breakdown, stream-wise subject highlights, and preparation strategies for ISC 2027 students.

Quick Facts: ISC Class 12 2026-27

ISC Class 12 Subject Group Structure

The ISC Class 12 curriculum is organised into four categories: a compulsory English component, and three subject groups from which students select their optional papers. Every candidate must sit the English examination. Beyond English, students typically choose four or five additional subjects drawn from Groups 1, 2, and 3 based on their chosen academic stream.

English (Compulsory for All Candidates)

English is the only subject that is compulsory for all ISC candidates. It is examined through two papers: Paper 1 (English Language) tests reading comprehension, formal writing, grammar, and composition. Paper 2 (Literature in English) assesses appreciation of prescribed prose, poetry, and drama texts from the CISCE anthology. The internal assessment for English contributes 20 marks toward the final English total.

Group 1: Languages

Students must offer at least one language from Group 1 in addition to English. Group 1 covers all major Indian regional languages, classical languages, and selected modern European languages. Each language subject follows a two-paper format (Language paper and Literature paper) similar in structure to the English examination.

Group 2: Science and Related Subjects

Group 2 covers the core science stream subjects, including Physics, Chemistry, Biology, Mathematics, and Computer Science, along with applied science disciplines. Students taking the science stream at ISC typically choose three or four subjects from this group. All science subjects are assessed through a theory paper and a school-conducted practical examination.

Group 3: Humanities, Commerce and Creative Arts

Group 3 covers humanities, social science, commerce, and creative disciplines. Students taking the humanities or commerce stream at ISC draw most or all of their optional subjects from this group. Subjects such as Economics, Accounts, History, Political Science, and Sociology are popular choices. Creative subjects like Art and Performing Arts have a significantly higher practical component than theory.

ISC Class 12 Streams: Science, Commerce and Humanities

While CISCE does not formally mandate fixed subject combinations, ISC schools typically guide students into three broad streams for Class 12 based on their Class 11 subject selection. The most common stream configurations are described below.

Science Stream

The Science stream at ISC is the most common path for students targeting engineering, medicine, research, or applied science careers. The typical subject combination includes Physics, Chemistry, and Biology (for the PCB track) or Physics, Chemistry, and Mathematics (for the PCM track), along with English and one language. Computer Science or Biotechnology can be taken as a fourth science elective. All science subjects carry a 70-mark theory paper and a 30-mark school-conducted practical examination.

Commerce Stream

The Commerce stream prepares students for careers in finance, business, accounting, economics, and management. The core commerce combination at ISC typically includes Accounts, Economics, and Commerce or Business Studies, with English and one language. Students may additionally opt for Mathematics or Computer Science as an elective within this stream, strengthening their quantitative ability for undergraduate business and finance programmes.

Humanities Stream

The Humanities stream at ISC covers a broad range of social sciences, languages, creative arts, and communication subjects. Students pursuing history, political science, psychology, sociology, geography, or media and communication careers typically select subjects from Group 3 along with English and a language from Group 1. This stream offers significant flexibility for students with interdisciplinary or creative interests.

ISC Class 12 Exam Pattern 2026-27

All ISC Class 12 examinations are written papers conducted by CISCE at registered school examination centres. Each theory paper follows a structured format, typically divided into a compulsory short-answer section (Section A) and a long-answer section (Section B) from which students choose a specified number of questions. Practical examinations and project assessments are conducted by each school under CISCE guidelines and submitted to the council.

ISC Class 12 Marking Scheme 2026-27

Every ISC subject is assessed out of a total of 100 marks. The split between theory and practical or internal marks varies by subject. The passing threshold for ISC is 40% in each individual subject, which is higher than the ICSE Class 10 threshold. Students who fail to clear 40% in any subject receive a fail in that subject on their ISC marksheet.

The ISC aggregate percentage is calculated using the marks obtained in the best four subjects other than English, combined with the English score. Universities and professional colleges use this aggregate for admission purposes. Students who appear for more than five subjects have their aggregate calculated using their best-performing combination.

ISC Class 12 Key Subject Highlights

The following sections provide a brief overview of what each major ISC subject area covers, helping students and parents understand the scope and depth of the 2026-27 curriculum before reviewing the full detailed syllabus pages.

English (Compulsory)

ISC English is assessed through two separate papers. Paper 1 (English Language) covers essay and composition writing, notice and report writing, reading comprehension of unseen passages, and grammar questions. Paper 2 (Literature in English) involves critical appreciation of prescribed prose, poetry, and drama texts including works from the CISCE Treasure Trove anthology and a prescribed drama. Both papers are three hours in duration and carry equal marks.

Science Stream: Physics, Chemistry, Biology, Mathematics

ISC science subjects are widely acknowledged for their comprehensive syllabus and depth of content. Physics covers mechanics, electrostatics, current electricity, optics, modern physics, and communication systems. Chemistry spans physical, organic, and inorganic chemistry, including electrochemistry, coordination compounds, and biomolecules. Biology includes reproduction, genetics, evolution, biotechnology, ecology, and human health. Mathematics covers relations and functions, calculus, algebra, probability, vectors, and three-dimensional geometry. Each science subject has a three-hour theory paper and a school-conducted practical examination contributing 30 marks.

Commerce Stream: Accounts, Economics, Commerce, Business Studies

ISC Commerce subjects are well-regarded for their alignment with undergraduate business and finance programmes. Accounts covers partnership firms, company accounts, cash flow statements, and financial statement analysis. Economics spans microeconomics (demand, supply, market structures) and macroeconomics (national income, banking, government budget, and balance of payments). Commerce covers trade, banking, insurance, warehousing, and business organisations. Business Studies focuses on management principles, financial management, and marketing.

Humanities: History, Political Science, Sociology, Psychology

ISC Humanities subjects develop critical thinking, analytical writing, and conceptual understanding of society, politics, and human behaviour. History covers Indian history from the early modern period through the contemporary era, as well as world history events in the twentieth century. Political Science spans Indian government and politics, international relations, and political theory. Sociology covers social institutions, stratification, change, and Indian social issues. Psychology covers biological basis of behaviour, cognitive processes, human development, and applied psychology.

Preparation Tips for ISC Class 12 Board Exam 2027

ISC Class 12 board examinations demand sustained effort, conceptual clarity, and strong written expression. Unlike purely objective assessments, ISC papers reward students who can articulate ideas clearly, apply concepts to new contexts, and demonstrate structured thinking across both short and long answers. The following strategies help students prepare effectively for ISC 2027.

Build Subject-Specific Study Plans Early

Each ISC subject has a distinct syllabus scope, question format, and preparation requirement. Students should create individual chapter-wise study plans for each subject at the start of the academic year rather than waiting for board exam term. Tracking completion of each chapter, completing NCERT and ISC reference materials in parallel, and scheduling regular subject-wise revision days ensures steady progress across all five or six papers simultaneously.

Prioritise English Throughout the Year

English Language and Literature are compulsory and contribute directly to the ISC aggregate. Consistent practice of formal essay writing, letter and report formats, and reference-to-context answers from prescribed literary texts is essential. Reading quality prose and literary criticism regularly improves both language fluency and the analytical writing required for the Literature paper. Students should aim to complete at least one timed writing practice per week throughout the academic year.

Master Practicals and Projects Concurrently with Theory

Science students often neglect practicals and projects until the exam term, which is a significant error. Practical skills require regular lab practice, and the 30-mark practical component is one of the most reliable scoring opportunities in the ISC science stream. Commerce and humanities students should begin project work early in the year to allow time for revisions, formatting, and a thorough understanding of project content before submission.

Solve CISCE Specimen Papers and Past Year ISC Papers

CISCE publishes official specimen papers for ISC that closely mirror the actual examination. Solving these papers under strict timed conditions reveals how questions are worded, which topics receive the highest weightage, and how marks are allocated within multi-part answers. Past year ISC papers from the preceding five to seven years, when analysed alongside official mark schemes, provide an excellent guide to examiner expectations across all subjects.

Focus on Answer Presentation and Word Limits

ISC examiners pay attention to the structure, precision, and completeness of answers. Long-answer questions reward students who present their responses with clear topic sentences, logical development, and a brief conclusion. In Mathematics and Science, showing all working steps is essential. In Language and Humanities papers, using subject-specific terminology correctly and maintaining appropriate word limits for essays and reports demonstrates command over the subject.

Frequently Asked Questions (FAQs)

What is ISC and who conducts it?

ISC stands for Indian School Certificate. It is a senior secondary (Class 12) examination conducted by the Council for the Indian School Certificate Examinations (CISCE), a private board of school education based in New Delhi. The ISC is equivalent to the Class 12 examinations conducted by CBSE, state boards, and other national boards.

Is English compulsory in ISC Class 12?

Yes. English is the only subject that is compulsory for all ISC Class 12 candidates without exception. All other subjects are selected based on the student's chosen stream and subject combination approved by the school.

How many subjects does an ISC student have to study?

ISC students must study a minimum of five subjects including English. Most students study five or six subjects. The maximum number of subjects a student may offer is typically determined by the school and CISCE guidelines. Students studying six subjects have their aggregate calculated on the best five performance scores, which can strategically benefit their final percentage.

What is the passing percentage for ISC Class 12?

Students must secure a minimum of 40% marks in each subject individually to pass. This is higher than the 33% requirement at ICSE Class 10. Failure to achieve 40% in any one subject results in a fail grade for that subject, which may affect eligibility for certain university programmes.

Does ISC have internal assessment?

Yes. Most ISC subjects include an internal or practical component worth 20 to 30 marks, which is assessed and submitted by the school throughout the academic year. This component is included in the final out of 100 marks for each subject. Science subjects have school-conducted lab practicals, while most other subjects have project-based internal assessment.

When are the ISC Class 12 board exams conducted?

The ISC Class 12 board examinations are conducted annually in February and March. For the 2026-27 academic session, the ISC 2027 examinations are expected to be held in February-March 2027. The official timetable is released by CISCE on www.cisce.org several months in advance of the examination period.

Is ISC recognised by universities across India and abroad?

Yes.
