CBSE Class 10 Science Sample Papers 2026-27
This is a comprehensive practice resource for students preparing for the CBSE Class X Science Board Examination (Subject Code 086). It contains 20 original sample papers, each carrying 80 marks and designed to be completed in 3 hours — matching the format of board examinations.
What's Inside:
The 20 papers are spread across three difficulty levels — Easy, Medium, and Hard — allowing students to build their confidence progressively. Each paper contains 39 questions divided into three sections:
Section A – Biology (approx. 25 marks): Topics include photosynthesis, reproduction, genetics, the nervous system, ecosystems, evolution, and more.
Section B – Chemistry (approx. 25 marks): Topics include chemical reactions, acids & bases, metals, carbon compounds, electrochemistry, and industrial processes.
Section C – Physics (approx. 30 marks): Topics include light (mirrors & lenses), electricity, magnetism, electromagnetic induction, and circuits.
Key Features:
All questions are stated to be original, created exclusively for this publication by Team Future Topper.
Diagram-based questions are included, matching the style expected in board examinations.
Every paper is followed by a comprehensive answer key with step-wise solutions aligned to the marking scheme.
Full syllabus coverage across all CBSE Class X Science units: Chemical Substances, World of Living, Natural Phenomena, Effects of Current, and Natural Resources.
Question types include MCQs, Assertion–Reason, short answer, and long answer questions — mirroring actual board paper patterns.
Who It's For:
Students of Class X appearing for the CBSE Science Board Exam who want structured, timed practice across varying difficulty levels.

Reviews
The question quality and marking-scheme solutions are genuinely strong and I improved my Science preparation significantly. The overall visual design and layout feel quite plain. Content quality makes it a clear recommendation regardless.
Homologous series, functional groups, isomers and important reactions like saponification appear with good question variety. Chemistry chapters that need application-level practice get it here.
Many students lose marks on diagram questions because they don't practice them enough. Having these in every paper built the habit of drawing accurate, labelled diagrams under time pressure.
The harder papers are at a difficulty level above what most students practice with. That additional challenge directly contributed to my ability to handle the actual board paper comfortably.
Concave and convex mirrors, refraction through lenses, human eye and atmospheric refraction questions span all formats from MCQ to long answer. Complete practice for a high-weightage chapter.
Sexual and asexual reproduction, human reproductive system and plant reproduction questions appear across papers. A chapter where students sometimes underestimate the analytical question types.
Natural selection, speciation and evidence of evolution questions in the harder papers go beyond simple definitions. Good preparation for a chapter with surprisingly analytical board questions.
Resistance in series-parallel combinations, power calculation and Joule's heating questions appear at varying difficulty. Good reinforcement of calculation skills for the Physics section.
For Science board exams every step matters. The answer keys show full working aligned to the marking scheme. Learning how to present solutions is as important as getting the answer right.
Inheritance of traits, sex-linked characters and evolution linkage questions in the harder papers require genuine conceptual understanding. Excellent practice for a conceptually rich chapter.
