FAQs on CBSE Science Past Year Paper with Solutions - 2024 (Set - 1)

1. What are the most important topics that usually come in CBSE Class 10 Science board exams?
Ans. CBSE Class 10 Science board exams focus on core topics including chemical reactions, heredity and evolution, electricity, magnetism, light refraction, acids and bases, and human physiology. Past year papers consistently emphasise practical applications and numerical problems alongside theoretical concepts. Reviewing previous year questions helps identify recurring themes and weightage patterns across different units.
2. How can I use past year papers to prepare better for my Class 10 Science board exam?
Ans. Past year question papers serve as authentic practice material that mirror actual exam patterns, difficulty levels, and time constraints. Students should attempt papers under timed conditions, identify frequently asked topics, and note the distribution of marks across short-answer and long-answer questions. This strategy reveals which concepts require deeper revision and helps build exam confidence through familiarity.
3. What's the difference between answering 1-mark and 5-mark questions in CBSE Science exams?
Ans. One-mark questions test direct factual recall and require concise, definition-based answers. Five-mark questions demand detailed explanations, diagrams, step-by-step reasoning, or experimental procedures with proper justification. Practising both question types from past papers reveals how to modulate answer length and depth, maximising marks allocation without unnecessary elaboration or incomplete responses.
4. Why do certain Science topics repeat across multiple years in CBSE board exams?
Ans. Topics like photosynthesis, refraction of light, and periodic classification appear repeatedly because they form foundational concepts linking multiple chapters and assess critical thinking skills. Examiners prioritise concepts with real-world applications and broader conceptual importance. Analysing past year solutions reveals these core, frequently tested areas worth extra revision focus and comprehensive practice.
5. How should I tackle numerical problems in CBSE Class 10 Science past year papers?
Ans. Numerical problems in electricity, light, and motion require clear identification of given values, relevant formulae, and systematic working. Students should practise unit conversions, draw labelled diagrams, and show calculations step-by-step using past paper solutions as reference guides. Referring to mind maps and flashcards helps consolidate formula applications and common numerical patterns across different topics efficiently.
