CBSE Class 10 Science 2026-27 Exam Analysis
The CBSE Class 10 Science Board Exam 2026 was held on 25th February (First Board Exam) and 18th May (Second Board Exam/Improvement). Subject experts and students have shared their feedback analysis after the exam. Here is what they’ve shared:
- Overall Difficulty: Easy to moderate in both attempts, with no out-of-syllabus questions reported.
- Biology: It was the easiest section. This involved mostly direct, NCERT-based, diagram and reasoning questions.
- Chemistry: Easy to moderate section – standard reactions & NCERT-based concepts.
- Physics: Numericals from Electricity and ray diagram questions from Light made this section the toughest, requiring careful formula application.
- Question Typologies: The paper combined MCQs, Assertion-Reason (True/False), competency-based, and case-study questions, which made it feel longer. While some students found the individual questions challenging to solve, others felt the difficulty level moderate and manageable.
This pattern (moderate overall, Physics as differentiator) has remained consistent across the last few years. It would be useful as a reference point when practising Class 10 Science Previous Year Papers for the next attempt.

Why Solve Class 10 Science Previous Year Papers?
Previous Year Papers are the actual board papers that reflect the same blueprint, question style, difficulty level, and answer format as the actual board examination. Solving them alongside Class 10 Science sample papers helps you understand how NCERT concepts turn into board-level questions.
This improves your ability in diagram accuracy, chemical equation balancing, and numerical presentation skills in a way examiners specifically award marks for. Additionally, it helps reduce exam anxiety and boost confidence to write the exam.
How to Solve Class 10 Science PYQs for Best Practice?
Practising thoroughly with PYQs can strengthen concept understanding across the Class 10 Science syllabus for 2027 Science board exams. But practising through these papers requires a strategy which can actually lead to real improvement.
Follow this simple strategy:
- Step 1: Solve the complete Science paper within 3 hours under exam-like conditions.
- Step 2: Compare your answers with the official CBSE marking scheme. Give special attention to scientific keywords, labelled diagrams, balanced chemical equations, and step-wise numerical solutions.
- Step 3: Revise the concepts where you lost marks. Focus on concepts, reactions, diagrams, formulae, and frequently confused topics. Use Class 10 science notes.
- Step 4: Move on to another year's Science paper and repeat the same process.
This strategy will help you identify the most frequently tested concepts, improve answer writing and surely build speed and accuracy.
FAQs
Q1. Was the CBSE Class 10 Science 2026-27 paper easy or tough?
Ans. Experts and students found both February and May 2026 attempts easy to moderate. Biology was the easiest, Chemistry was easy to moderate, and Physics was the most difficult within the prescribed syllabus.
Q2. What is the weightage of Physics, Chemistry and Biology in the CBSE Class 10 Science paper?
Ans. As per the current blueprint, Biology and Chemistry carry 25 marks each (Total 50) in the units "World of Living" and "Chemical Substances", while Physics carry 25 marks for the unit "Natural Phenomena" and 5 marks for the unit "Effects of Current" with total of 25 marks.
Q3. Should I solve previous year papers and sample papers first before the Science exam? Ans. First, complete your NCERT textbook. Once you have learned the concepts, start with past papers, then practice solving sample papers. This helps develop speed and handle the paper with a mix of MCQ, case studies, and L.A. questions in a timed environment.
Q4. What are the highest weightage chapters in Class 10 Science?
Ans. The highest-weightage chapters that mostly appear in multiple years' papers are Metals and Non-Metals (10 marks), Light - Reflection and Refraction (10 marks) and Life Processes (9 marks).
Q5. Where can I find CBSE Class 10 Science PYQ with solution PDF for free?
Ans. You can download the Class 10 Science Board Paper PDF with the official marking scheme from the table above for 2026-27 (including the 2nd/improvement attempt).
