Frequently Asked Questions

Q1. What is the official exam structure and marking scheme for Class 10 Science?

Total Marks: 80 (theory) + 20 (internal assessment) Duration: 3 hours

Subject-wise weightage: Physics (25 marks), Chemistry (25 marks), Biology (30 marks)

Internal assessment includes practical work, project work, and periodic assessments.

Q2. How should I manage time between Physics, Chemistry, and Biology in the exam?

Allocate time based on marking weightage: spend approximately 60-65 minutes on Biology (30 marks), 50-55 minutes each on Physics and Chemistry (25 marks each), with remaining time for revision. Practice section-wise timing during sample paper attempts to develop efficient time management strategies.

Q3. Which are the most important topics for Class 10 Science based on official weightage?

High-yield topics as per official pattern:

• Physics: Light (Reflection & Refraction), Electricity, and Magnetic Effects of Electric Current
• Chemistry: Acids Bases and Salts, Carbon and its Compounds, and Metals and Non-metals
• Biology: Life Processes, Control and Coordination, and How do Organisms Reproduce

These topics consistently appear in board exams with higher weightage.

Q4. How many official sample papers should I solve for Science preparation?

Solve the official CBSE sample paper multiple times (at least 4-5 attempts) plus 6-8 additional practice papers covering Physics, Chemistry, and Biology comprehensively. Begin intensive practice 2 months before board exams after completing the entire syllabus to focus on integration of concepts, time management, and thorough revision.

Q5. How should I approach case study questions in Science effectively?

Read carefully: Analyze the given scientific scenario or data thoroughly before attempting sub-questions. Connect concepts: Link the case study to theoretical concepts from Physics, Chemistry, or Biology. Use scientific terminology: Apply proper scientific language and reasoning in your responses. Practice regularly: Solve case studies from various scientific contexts to build familiarity with different question patterns and real-world applications.
