CBSE Class 11 Exam Pattern 2026-27: Marks, Typology and Practicals
The CBSE Class 11 exam pattern tells you how each subject's 100 marks are split between the theory paper and practical, project or internal assessment. Class 11 is a school-conducted exam, so your school sets the papers and dates, but CBSE's 2026-27 curriculum fixes the marks split, the question typology and the pass rules that every affiliated school follows.
This page gives the subject-wise marks split, the question typology for Physics, Chemistry and Mathematics, the practical and internal assessment components, and what all of it means for how you prepare. CBSE's curriculum says Class XI assessment should be similar to the Class XII board pattern, so practising in that format now pays off in Class 12.

Question paper design
CBSE groups theory marks by the type of thinking a question tests. The weightage below is from the 2026-27 subject documents. Schools may vary the internal distribution of questions, but the overall weightage stays the same.
Typology | Physics (70) | Chemistry (70) | Mathematics (80) |
|---|---|---|---|
Remembering and understanding | 27 (38%) | 28 (40%) | 44 (55%) |
Applying | 22 (32%) | 21 (30%) | 20 (25%) |
Analysing, evaluating and creating | 21 (30%) | 21 (30%) | 16 (20%) |
Total | 70 | 70 | 80 |
Internal choice: Chemistry and Mathematics papers carry no overall choice, but about 33% internal choice in all sections.
No chapter-wise weightage within a paper: All chapters must be covered; unit marks guide how many questions come from each unit.
Practical and internal assessment components
Physics practical (30 marks)
Component | Marks |
|---|---|
Two experiments, one from each section | 14 |
Practical record | 5 |
One activity | 3 |
Investigatory project | 3 |
Viva on experiments, activities and project | 5 |
Total | 30 |
Chemistry practical (30 marks)
Component | Marks |
|---|---|
Volumetric analysis | 8 |
Salt analysis | 8 |
Content-based experiment | 6 |
Project work | 4 |
Class record and viva | 4 |
Total | 30 |
Biology practical (30 marks)
Component | Marks |
|---|---|
One major experiment | 5 |
One minor experiment | 4 |
Slide preparation | 5 |
Spotting | 7 |
Practical record and viva | 4 |
Project record and viva | 5 |
Total | 30 |
Mathematics internal assessment (20 marks)
Component | Marks |
|---|---|
Periodic tests (best two of three, averaged) | 10 |
Mathematics activities | 10 |
Total | 20 |
English Core internal assessment (20 marks)
Listening carries 5 marks, speaking 5 marks and the project 10 marks (5 for the report and 5 for the viva).
What the pattern means for you
Theory carries most of the risk: In a 70-mark theory paper, each mark is about 1.4% of the subject. Two careless 3-mark answers can cost you a grade.
Practicals must be passed on their own: You need 33% in practical as well as in theory. A strong theory score does not cover a weak practical.
Analytical questions decide top grades: Physics and Chemistry give 30% of theory marks to analysing and evaluating. Practise case-based and assertion-reason questions, not only definitions.
No negative marking: Attempt every question. A partially correct method still earns step marks in numericals.
Grading scale
Marks | Grade |
|---|---|
91 to 100 | A1 |
81 to 90 | A2 |
71 to 80 | B1 |
61 to 70 | B2 |
51 to 60 | C1 |
41 to 50 | C2 |
33 to 40 | D |
32 and below | E (Essential Repeat) |
CBSE suggests absolute grading for Class XI. The pass and promotion rules are explained on the CBSE Class 11 passing marks and cut-off page.
Time management and exam-day strategy
Use the reading time well: Mark the questions you can answer fully and those that need more thought before you start writing.
Start with your strongest section: Securing easy marks early reduces pressure for the harder questions.
Budget about 2.3 minutes per mark: In a 3-hour, 70-mark paper, this leaves around 20 minutes to revise.
Show working in numericals: Write the formula, substitution and unit. Step marks add up.
Draw labelled diagrams: Biology, Physics and Geography answers score better with neat, labelled figures.
Older pages may still show earlier marks splits, so follow the 2026-27 subject curriculum on the CBSE Academic website.
