- Most subjects have 100 marks in total. Science subjects have 70 theory marks, and many other subjects have 80 theory marks.
- You must pass theory and practical or internal marks separately. A high practical score cannot cover a weak theory paper.

Three Types of Questions in the Theory Paper
| Question Type | Weightage | What It Checks | Examples |
| Competency-Based | 50% | Understanding and use of concepts | Case studies, source-based, passage-based and assertion-reason questions |
| MCQs (Objective) | 20% | Facts, definitions and basic ideas | Choose the correct option |
| Short and Long Answers | 30% | Writing, explaining and solving step by step | Very short, short (2–3 marks) and long (4–6 marks) answers |
Insight: Only 30% of the paper needs long written answers. The other 70% is made of MCQs and competency-based questions. So reading and thinking skills now matter as much as writing skills.

Other Popular Subjects – Marks Guide
The sources checked for this article list the subjects above. The table below shows the usual split for some other subjects, as used in earlier CBSE schemes. Please confirm each one in the 2026-27 curriculum.
| Subject | Theory Marks | Practical / Internal Marks |
| History | 80 | 20 |
| Political Science | 80 | 20 |
| Geography | 70 | 30 |
| Computer Science | 70 | 30 |

What Is Inside the Practical and Internal Marks?
- Science (30 marks): Practical exams, experiments and viva.
- Commerce (20 marks): Project work and viva voce.
- Mathematics (20 marks): Internal assessment and Maths activities.
- English Core (20 marks): Listening 5 marks, Speaking 5 marks and Project 10 marks.
- Humanities: Projects, map work or practicals, depending on the subject.
Note: Internal marks are given by your school. Do not ignore them, because they are 20% to 30% of your total marks.
Passing Marks – What You Need to Clear
You must score at least 33% in the theory paper and at least 33% in the practical or internal part. Both are checked separately. The table below shows the approximate marks.
| Part | Maximum Marks | About 33% (Calculated) |
| Theory – Science subjects | 70 | About 23 |
| Practical – Science subjects | 30 | About 10 |
| Theory – Commerce, Maths, English | 80 | About 26 |
| Internal – Commerce, Maths, English | 20 | About 7 |
Note: The exact rounding is decided by CBSE rules. Use these numbers only as a guide.
Example: In Physics, a student gets 22 out of 70 in theory and 28 out of 30 in practical. The total is 50, but the theory marks are below the 33% mark. As per the separate-passing rule, the student will not clear the theory part. So do not depend on practical marks to save a weak paper.

How to Use the Sample Paper Properly

- Check your answers with the official marking scheme. Notice how marks are given for steps and key points.
- Make a list of the questions you lost marks on and the reason: concept, speed or carelessness.
- Revise those chapters and attempt the paper again after a few days.
Why Competency-Based Questions Need Special Practice
A normal question may say: “Define inflation.” A competency-based question gives you a short case about price changes in a market and asks you to explain the cause. You cannot answer it by rote learning. You must understand the idea and apply it.
- Case-based: Read the case slowly. Underline the key facts before you answer.
- Source-based: Use the data, picture or passage given in the question. Do not add outside facts unless asked.
- Assertion-reason: First decide if each statement is true. Then check whether the reason explains the assertion.
Subject-Wise Preparation Tips
- Physics, Chemistry and Biology: Learn diagrams and formulas, solve numericals daily and finish practical file work on time.
- Mathematics: Practise every chapter with steps written clearly. Revise formulas every week.
- Accountancy, Business Studies and Economics: Practise case studies and keep your project and viva answers ready.
- English Core: Read passages daily, practise writing formats and prepare for listening and speaking tasks.
- History, Political Science and Geography: Prepare short notes, practise map work and write answers in clear points.

| Part of the Paper | Marks | Suggested Time |
| MCQs | 16 | 25 minutes |
| Competency-Based Questions | 40 | 70 minutes |
| Short and Long Answers | 24 | 65 minutes |

Note: This is a simple time guide made for practice. Adjust it after you solve a few sample papers.
Month-Wise Study Plan Till the Board Exam

| October – November 2026 | Finish the full syllabus. Prepare notes and complete practical files and projects. |
| December 2026 | First full revision. Solve one sample paper every week for each main subject. |
