FAQs on CBSE Science Past Year Paper with Solutions - 2024 (Set - 3)

1. What are the most important topics that appeared in CBSE Science Class 10 board exams 2024?
Ans. The 2024 CBSE Science board exam covered key topics including photosynthesis and respiration, heredity and evolution, electricity and magnetism, chemical reactions, and the human nervous system. Students should focus on these high-weightage areas when revising past year papers, as they consistently appear across multiple question sets. Refer to mind maps and flashcards on EduRev to identify frequently tested concepts quickly.
2. How do I identify which questions from past year papers are most likely to repeat in upcoming CBSE exams?
Ans. Certain question patterns repeat consistently-particularly on carbon cycle, Ohm's law applications, and refraction of light through lenses. By analysing multiple past year question papers from 2024 onwards, students can spot these recurring themes. Examine the distribution of short-answer and long-answer questions across sets to predict exam structure and prioritise revision accordingly for maximum marks.
3. What's the difference between the question types asked in CBSE Science 2024 Set 1, Set 2, and Set 3 papers?
Ans. The three sets from 2024 maintain similar difficulty levels and question distribution but vary in specific scenarios and numerical examples used. Set 3 emphasises application-based problems and real-world connections more heavily than purely conceptual recall. All sets follow identical marking schemes and weightage patterns, so solving all three strengthens problem-solving versatility rather than introducing fundamentally different topics.
4. Why do I keep making calculation mistakes in CBSE Science numerical questions on electricity and magnetism?
Ans. Common errors occur from misidentifying resistance values, forgetting unit conversions (ohms to kilohms), or applying incorrect formulas for series versus parallel circuits. Students often confuse current direction with conventional flow, leading to sign errors. Practise numerical problems systematically using past year papers while noting down formula applications step-by-step to build accuracy and catch mistakes before final submission.
5. Which topics in CBSE Science Class 10 have the highest chance of appearing as long-answer questions worth 5 marks?
Ans. Topics like photosynthesis mechanisms, human reproduction processes, and electromagnetic induction consistently appear as 5-mark long-answer questions requiring explanatory depth. Respiration pathways, evolution evidence, and circuit analysis also feature prominently in extended-response formats. Study past year question papers to recognise the exact depth required-focus on cause-and-effect relationships, labelled diagrams, and step-by-step biological processes for comprehensive answers that secure full marks.
