CBSE Class 10 Science Sample Papers 2026-27
Prepare for the Science board exam with three free sample papers from Future Topper, built for the CBSE Class 10 2026-27 session. Each paper is designed by experienced Physics, Chemistry and Biology teachers to reflect the current exam pattern, covering numericals, diagram-based questions, assertion-reason and case-based questions exactly as they appear in the actual board question paper. These are practice papers created by Future Topper and are not official CBSE sample papers, though they closely follow the CBSE syllabus and marking scheme for the year.
Every paper can be downloaded for free as a PDF and comes with a complete answer key and marking scheme, so students can check their own work and understand exactly where marks are gained or lost.
CBSE Class 10 Science Exam Pattern 2026-27
The Science theory paper (code 086) carries 80 marks, spread across five sections ranging from objective type questions to case-based questions, with a further 20 marks awarded through internal assessment, which includes practical work. The table below shows the typical section wise distribution followed in the Future Topper sample papers.
Section | Question Type | Marks |
Section A | 20 objective/MCQ questions (1 mark each) | 20 marks |
Section B | 6 very short answer questions (2 marks each) | 12 marks |
Section C | 7 short answer questions (3 marks each) | 21 marks |
Section D | 3 long answer questions (5 marks each) | 15 marks |
Section E | 3 case-based/source-based questions (4 marks each) | 12 marks |
Internal Assessment | Periodic test, multiple assessment, portfolio, practical work | 20 marks |
Download CBSE Class 10 Science Sample Papers
Three separate papers are available below, arranged in a suggested order of use. Each includes a full answer key.
Paper | Best Used For | Download |
Sample Paper 1 | Balanced difficulty, good starting point for early revision | |
Sample Paper 2 | Slightly higher difficulty, useful for mid-term practice | |
Sample Paper 3 | Full length mock test, ideal for final revision |
Syllabus Covered in These Sample Papers
The sample papers cover all five units of the Science syllabus, combining Physics, Chemistry and Biology in the same proportion prescribed by CBSE. Topics include chemical reactions and equations, acids bases and salts, metals and non-metals, carbon and its compounds, periodic classification of elements, life processes, control and coordination, how organisms reproduce, heredity, light and the human eye, electricity, magnetic effects of electric current, sources of energy and our environment.
Unit | Marks | Broad Topics |
Chemical Substances - Nature and Behaviour | 25 marks | Chemistry |
World of Living | 25 marks | Biology |
Natural Phenomena | 12 marks | Physics |
Effects of Current | 13 marks | Physics |
Natural Resources | 5 marks | Biology/Environment |
How to Prepare Using These Sample Papers
• Attempt numerical problems on electricity, refraction and reflection under timed conditions, showing complete step wise working for full marks.
• Practise labelled diagrams for topics like the human eye, heart, nephron and electric circuits, since diagram-based questions are frequently asked.
• Revise balanced chemical equations and their types before attempting questions from the chemistry section.
• For case-based and assertion-reason questions, read the passage or statements carefully before selecting an answer, rather than relying on guesswork.
• After finishing each paper, compare your answers with the marking scheme and note recurring mistakes to focus on during revision.
Tips to Score Well in the Science Board Exam
• Learn the exact definitions and laws (such as the laws of reflection or refraction) word for word, since examiners look for precise terminology.
• Practise drawing neat, labelled diagrams with a pencil and scale, as presentation carries weight in diagram-based questions.
• Show all steps in numerical problems, including formulas and units, since partial marks are awarded for correct method even if the final answer is wrong.
• Revise the periodic table trends and NCERT in-text and exercise questions thoroughly, as many board questions are adapted directly from them.
Frequently Asked Questions
Are these Science sample papers official CBSE papers?
No, they are prepared by the Future Topper academic team based on the CBSE syllabus and exam pattern for 2026-27, and are not published by CBSE.
Are the sample papers free to download?
Yes, all three sample papers are available as free PDF downloads, along with their answer keys.
Do these papers cover Physics, Chemistry and Biology equally?
Each paper covers all three disciplines in the same broad proportion prescribed by CBSE, so students get balanced practice across the entire syllabus.
Will these papers help with numerical and diagram-based questions?
Yes, each paper includes numerical problems from Physics along with diagram-based questions from Biology and Physics, matching the current exam trend.
How important is the internal assessment for Science?
Internal assessment carries 20 marks out of 100 and includes periodic tests, practical work and a portfolio, so consistent lab work and class tests through the year matter alongside board exam preparation.
