CBSE Class 10 Exam Pattern 2027: Key Highlights

CBSE Class 10 Marking Scheme 2026-27: Theory and Internal Assessment

The CBSE Class 10 assessment scheme divides the total marks into two major components: the annual written examination and internal assessment conducted by schools.

Students will have to appear for an 80-mark theory examination in each applicable subject. The remaining 20 marks will be awarded through school-based assessment activities. This structure ensures that students are evaluated on both their written examination performance and their academic progress throughout the year.

What is included in CBSE Class 10 Internal Assessment?

Internal assessment is an important part of the CBSE Class 10 examination system. It allows schools to evaluate students through activities conducted during the academic session rather than depending entirely on the final board examination.

Depending on the subject, internal assessment may include periodic tests, multiple assessment activities, practical or laboratory work, subject enrichment activities and portfolio evaluation.

For subjects such as Science, practical activities and laboratory-based learning help students understand scientific concepts through experiments. Similarly, language subjects may include listening, speaking, reading and writing activities to evaluate communication skills.

CBSE Class 10 Subject-Wise Exam Pattern 2026-27

CBSE has released separate sample question papers for Mathematics Basic, Mathematics Standard, Science, Social Science, English Language and Literature, English Communicative, Hindi A and Hindi B. The subject-wise examination pattern differs according to the syllabus and learning objectives. Here is a detailed breakdown of the major subjects.

1. CBSE Class 10 Mathematics Exam Pattern 2026-27

The CBSE Class 10 Mathematics examination is conducted in two levels: Mathematics Basic (241) and Mathematics Standard (041). Both examinations carry 80 marks and have a duration of three hours.

The two papers follow the same broad question paper structure, but their difficulty levels differ. Mathematics Standard is intended for students who wish to continue studying Mathematics at the senior secondary level, while Mathematics Basic is designed for students who prefer a comparatively less challenging level.

According to the 2026-27 sample question paper, the Mathematics examination consists of 38 compulsory questions divided into five sections.

CBSE Class 10 Maths Question Paper Structure

Detailed explanation of Mathematics sections:

• Section A: This section contains 18 multiple-choice questions and two assertion-reason questions. Each question carries one mark. Students need to select the correct option based on their understanding of mathematical concepts.

• Section B: It contains five very short-answer questions carrying two marks each. Students are expected to solve questions involving calculations, formulas and basic mathematical reasoning.

• Section C: This section includes six short-answer questions of three marks each. Students may need to show calculation steps and explain the method used to reach the answer.

• Section D: It consists of four long-answer questions carrying five marks each. These questions generally require detailed calculations, appropriate formula application and logical steps.

• Section E: The final section includes three case study-based questions carrying four marks each. Each question is divided into sub-parts carrying 1, 1 and 2 marks.

The sample paper provides internal choices in selected questions in Sections B, C and D. Students also get choices in the two-mark sub-parts of the case study section. The use of calculators is not permitted.

Algebra carries the highest weightage, followed by Geometry and Trigonometry. Students should not ignore any unit, as questions can be asked from all prescribed areas of the syllabus.

CBSE offers two Hindi courses at the secondary level: Hindi Course A and Hindi Course B. Both subjects carry 80 marks for the written examination, while the remaining 20 marks are allocated to internal assessment.

The two courses have separate syllabi, sample papers and marking schemes. Therefore, students should prepare according to the course selected by their school.

The Hindi examinations generally assess students through the following areas:

• Reading Comprehension: Questions based on unseen passages to evaluate reading and interpretation skills.
• Grammar: Questions covering prescribed grammatical concepts and language usage.
• Writing Skills: Questions based on creative and formal writing formats.
• Literature: Questions from prescribed prose, poetry and other literary texts.

CBSE Class 10 Exam Pattern 2026-27: Competency-Based Questions

One of the important features of the CBSE examination framework is its focus on competency-based learning. Students are expected to demonstrate conceptual understanding and apply their knowledge to different situations instead of relying entirely on memorisation.

The question papers include different formats to evaluate students' analytical thinking, reasoning, comprehension and problem-solving abilities.

The major question types students should prepare for include:

1. Multiple-Choice Questions (MCQs): MCQs carry one mark each in the relevant sections. Students have to select the correct answer from the given options. These questions may test factual knowledge, conceptual understanding, calculations and application of concepts.

2. Assertion-Reason Questions: These questions contain two statements: Assertion (A) and Reason (R). Students need to determine whether both statements are correct and whether the reason appropriately explains the assertion.

3. Case Study-Based Questions: Case-based questions provide a passage, situation, experiment, data set or real-life example followed by multiple sub-questions. Students must analyse the information and apply their subject knowledge to answer the questions.

4. Source-Based Questions: These questions are particularly relevant to Social Science and may also appear in other subject formats. Students are required to interpret a given source, passage, image or information and answer questions based on it.

5. Short and Long Answer Questions: Descriptive questions evaluate students' ability to explain concepts, present logical arguments, solve problems and provide relevant examples. Students should write answers according to the marks allotted to each question.

6. Diagram and Map-Based Questions: Science examinations may include diagram-based and experimental questions, while Social Science includes map-based questions. Students should practise drawing and labelling diagrams and identifying important geographical and historical locations.

CBSE Class 10 Exam Pattern 2026-27: Important Preparation Tips

Understanding the marking scheme is only the first step towards preparing for the CBSE Class 10 Board Examination 2027. Students should also develop a subject-wise preparation strategy based on the question paper structure.

Here are some important preparation tips:

1. Download the latest sample papers: Practise the official 2026-27 sample papers to understand the question formats, section-wise distribution and examination instructions.

2. Understand the marking scheme: Refer to the official marking schemes to learn how marks are awarded for different answers, calculations, diagrams and explanations.

3. Practise competency-based questions: Solve case studies, assertion-reason questions, source-based questions and application-based problems regularly.

4. Focus on NCERT textbooks: Students should thoroughly revise the prescribed NCERT textbooks and exercises, as they form an important foundation for board examination preparation.

5. Improve time management: Attempt full-length mock tests within the three-hour examination duration to develop speed and accuracy.

6. Revise important diagrams and maps: Science diagrams and Social Science map work should be practised regularly to avoid losing marks in these sections.

7. Complete internal assessment work: Students should submit practical files, assignments, projects and portfolios within the deadlines provided by their schools.

CBSE Class 10 Passing Marks 2026-27
