Preparing for class 10 science without knowing the exact paper pattern is like revising without a map. You may study hard. But you may not study smart.
For the academic year 2025–26, the class 10 science paper pattern 2026 defined by CBSE is clear, structured, and highly application-driven. If you understand the marks distribution, unit-wise weightage, and question typology, you can align your preparation precisely with the cbse syllabus for class 10 science.
At Aakash Institute, we always tell students: Don’t just finish chapters. Decode the pattern.
So, let’s break it down for you.
CBSE Class 10 Science Paper Pattern 2026 (Theory + Internal)
The CBSE Board follows a dual evaluation structure:
- Theory Paper: 80 Marks
- Internal Assessment: 20 Marks
Total: 100 Marks
Theory Paper Structure (80 Marks)
| Section | Type of Questions | No. of Questions | Marks per Question | Total Marks |
| Section A | MCQs (Q1–Q20) | 20 | 1 | 20 |
| Section B | Very Short Answer | 6 | 2 | 12 |
| Section C | Short Answer | 7 | 3 | 21 |
| Section D | Long Answer | 3 | 5 | 15 |
| Section E | Case-Based Questions | 3 | 4 | 12 |
Duration: 3 Hours
There is no overall choice. However, internal choices are provided in select questions.
This format makes the cbse class 10 science question paper heavily balanced. It tests recall, clarity, logic, and application.
Section-Wise Strategy for Class 10 Science
Here is a section-wise approach:
Section A: MCQs (20 Marks)
Objective but tricky.
These questions test conceptual clarity from across Physics, Chemistry, and Biology. Many students underestimate MCQs. They shouldn’t.
Focus on:
- Definitions with precision
- Diagrams
- Units and formula-based reasoning
- Concept-based elimination
Practising important questions for class 10 science from MCQ format is critical here.

Section B & C: Short Answer Questions (33 Marks Combined)
These sections demand structured writing. For 2-mark answers:
- Write crisp definitions.
- Avoid over-explanation.
- Include key terms from NCERT.
For 3-mark answers:
- Add labelled diagrams where required.
- Mention laws or principles explicitly.
- Use stepwise explanations.
Students often write “almost correct” answers. That costs half marks. Precision matters in class 10 science.
Section D: Long Answer Questions (15 Marks)
These are your scoring anchors. 5-mark questions usually come from:
- Chemical reactions and mechanisms
- Electricity numericals
- Life processes explanations
- Heredity diagrams
Structure long answers in parts. Use subheadings if needed. Examiners appreciate clarity.
Section E: Case-Based Questions (12 Marks)
Application-focused. You may get:
- Experimental data
- Real-life scenarios
- Graphs
- Short passages
This section checks analytical thinking. Students who only memorise struggle here. Those who understand concepts score full marks.

CBSE Class 10 Science Marks Weightage (Unit-Wise)
Understanding weightage helps prioritise revision according to the cbse syllabus for class 10 science.
Unit I: Chemical Substances – Nature and Behaviour (Approx. 31.25%)
Highest weightage.
Chapters include:
- Chemical Reactions and Equations
- Acids, Bases and Salts
- Metals and Non-Metals
- Carbon and its Compounds
Metals and Non-Metals is concept-heavy. Carbon compounds require clarity in bonding and properties. This unit alone can decide your grade.
Unit II: World of Living (Approx. 31.25%)
Biology dominance. Key chapters:
Life Processes carries maximum marks here.
Diagrams = marks. Flowcharts = clarity. Revise from NCERT line by line.
Unit III: Natural Phenomena (Approx. 15%)
Includes:
Ray diagrams are compulsory practice. Even small errors reduce marks.
Unit IV: Effects of Current (Approx. 16.5%)
Electricity and Magnetic Effects. Numericals must include:
- Given
- Formula
- Substitution
- Final answer with unit
Presentation matters here.
Unit V: Natural Resources (Approx. 6%)
Lower weightage but scoring. Questions are direct and theory-based. Do not ignore it.
Internal Assessment (20 Marks)
Internal marks often decide rank differences. Break-up:
| Component | Marks |
| Periodic Assessment | 5 + 5 |
| Portfolio | 5 |
| Subject Enrichment (Lab Activities) | 5 |
Maintain practical files properly. Many students lose easy marks here.
