CBSE Class 12 Exam Pattern 2026-27

The Central Board of Secondary Education (CBSE) has set out the Class 12 examination pattern for the 2026-27 session in line with the National Education Policy (NEP) 2020. It is relevant to students preparing for CBSE Class 12 board examinations, as it describes the mix of question types and assessment components used in the pattern.

The theory-paper distribution described here comprises 50% competency-based questions, 20% multiple-choice questions and 30% short- and long-answer questions. Marks for theory and practical or internal assessment depend on the subject, and the listed subject groups have a three-hour exam duration. Students should confirm the current syllabus and marking scheme for each of their subjects through the official CBSE Academic website.

Subject-Wise Marks and Assessment

The theory and non-theory components are not identical across all subjects. Science subjects such as Physics, Chemistry and Biology include practical examinations, while Commerce subjects include project work and viva voce. Mathematics, languages and Humanities or Arts subjects have their own assessment arrangements.

This table gives the general pattern described for these subject groups; the exact allocation and assessment rules may differ between individual subjects. Check the latest CBSE subject-specific documents before relying on a particular marks split.

Theory Paper Question Types

The stated theory-paper breakdown combines questions that test application and understanding with objective questions and written responses. Together, the three categories account for the full theory-paper weighting.

Competency-Based Questions: 50%

Competency-based questions assess whether students understand a topic and can apply what they have learned. They may use case studies, passages, graphs, other source material or assertion-reasoning formats. A question may present a situation or information to analyse rather than simply ask for a definition recalled from memory.

Students can prepare by reading concepts carefully and practising questions that require them to interpret information, apply ideas and solve problems.

Multiple-Choice Questions: 20%

Multiple-choice questions provide answer options from which students select the correct response. They may test facts, definitions, basic concepts or the ability to understand and compare information. Read each question in full and check that the chosen option answers what is being asked. Textbooks and sample papers can help students practise this format.

Short- and Long-Answer Questions: 30%

These questions require students to write their own responses. Short answers may carry 2 or 3 marks, while long answers may carry 4 to 6 marks, depending on the subject and paper. Very short answer questions may also appear. Students should present explanations clearly, include the main points requested and show working steps for Mathematics or Science problems where needed.

Minimum Passing Marks

The stated minimum is 33% in the theory paper and 33% in the practical or internal assessment separately, wherever both components apply. For example, the listed Science pattern has separate theory and practical components, so students should check that they meet the requirement for each part rather than relying only on the combined total.

Passing requirements should be confirmed against the latest CBSE rules for the specific subject. The applicable assessment components and marks can vary by subject.

Where to Check the Syllabus and Marking Scheme

The CBSE Academic website provides academic documents, including syllabi, sample question papers and marking schemes when they are available. Students should select the documents that match their own subjects to check included topics, question formats and subject-wise marks.

Preparation Guidance

Start by reviewing the syllabus for each subject and planning time to cover its topics. Focus on understanding concepts, then practise case-based, source-based and assertion-reasoning questions alongside MCQs and written answers.

For Mathematics and Science, work through problems and show the required steps. For languages and other theory subjects, practise writing clear, relevant responses. Try sample papers within the three-hour duration listed for the subject groups, then review mistakes and revisit topics that need more work. Students should also prepare for any practicals, experiments, viva, project work, listening or speaking assessments, and map work included in their subjects.

Students preparing for the 2026-27 CBSE Class 12 examinations should use this general pattern as a guide and verify the latest subject-wise syllabus and marking rules on the CBSE Academic website.
