Concepts, Question Trends & How to Score 90+ in 2025 Examination
Detailed analysis of Dr. Homi Bhabha Exam 2023 & 2024 for Class 6 and 9. Explore question patterns, important topics, paper trends, and expert preparation strategies to score 90+ in 2025.
Introduction
The Dr. Homi Bhabha Balvaidnyanik Competition is one of the most respected science exams in Maharashtra, designed to test a student’s grasp of real-world science concepts.
After analyzing both 2023 and 2024 Test papers for Class 6 and Class 9, this blog presents a detailed breakdown — covering topic-wise trends, difficulty levels, and winning preparation strategies for the 2025 exam.
CLASS 6 PAPER ANALYSIS (2023 & 2024)
Biology
- 2023 focused on plants and nutrition.
- 2024 emphasized human systems — especially digestion and respiration.
- Key topics: Photosynthesis, transpiration, balanced diet, deficiency diseases.
📖 Tip: Practice diagrams of leaf, flower, and digestive system with proper labeling.
Chemistry
- Everyday science questions like dissolving, evaporation, and filtration dominated both papers.
- Separation techniques, solubility, and acids-bases were frequent topics.
📖 Tip: Understand processes like evaporation vs boiling — questions were mostly reasoning-based.
Physics
- 2024 included more numericals (speed, motion).
- Light, sound, and friction were tested consistently both years.
📖 Tip: Remember units and conversions (1 km/hr = 5/18 m/s).
Environment & GK
- Topics on pollution control, renewable energy, and ISRO missions (Aditya-L1, Chandrayaan-3) featured prominently.
📖 Tip: Read one science news article daily for updated awareness.
Question Pattern
| Year | Conceptual | Numerical | Diagram-Based | GK |
|---|---|---|---|---|
| 2023 | 60% | 10% | 15% | 15% |
| 2024 | 75% | 15% | 20% | 10% |
Class 6 — Key Takeaways
- More reasoning and application-based questions in 2024.
- Focus on daily-life science — e.g., “Why does curd form faster in summer?”
- Diagrams and one-line definitions carry 10–12 easy marks.
Prep Tip: Revise “Changes Around Us”, “Plants”, and “Body Movements” chapters from Class 6 NCERT and State Board book..
CLASS 9 PAPER ANALYSIS (2023 & 2024)
Physics
- Core focus: Motion, Laws of Motion, Energy, Light, Electricity.
- 2024 had more numericals; 2023 was more conceptual.
- Frequent topics: Acceleration, Ohm’s Law, Work & Power, Refraction.
📖 Tip: Keep a formula card handy — V = IR, Work = Force × Distance, Power = Work/Time.
Chemistry
- Both years covered Chemical Reactions, Acids/Bases, and Metals/Non-Metals.
- 2024 highlighted real-world connections — rusting, neutralization, acid rain.
📖 Tip: Learn reaction types and examples — Combination, Decomposition, Double Displacement.
Biology
- Concept weightage increased in 2024 (Cell, Tissues, Life Processes).
- Function-based questions like “Why does the heart have valves?” replaced pure definitions.
📖 Tip: Revise cell organelles, diagrams, and human systems (digestive, respiratory, circulatory).
Environment & GK
- Questions on ISRO missions, pollution control, and climate awareness were frequent.
- 2024 also touched on renewable energy and sustainability.
📖 Tip: Remember 2–3 ISRO missions with their launch year and purpose.
Question Pattern
| Year | Conceptual | Numerical | GK/Current Science |
|---|---|---|---|
| 2023 | 65% | 15% | 20% |
| 2024 | 80% | 20% | 10% |
Class 9 — Key Takeaways
- Shift from memory-based to applied science questions.
- Expect multi-step reasoning or “match the process” type items.
- Master numericals, equations, and logic-based reasoning for 2025.
📘 Prep Tip: Revise core NCERT/State chapters — Motion, Force & Laws, Work & Energy, Atoms & Molecules, Cell & Tissues.
Final Recommendations for 2025
- Study conceptually, not memorization-based.
- Focus on why/how explanations (applied reasoning).
- Revise diagrams & definitions daily.
- Solve previous year papers & mock tests weekly.
- Practice with Neev Concept Sheets for final 3-day revision.
Conclusion
The 2023 and 2024 Dr. Homi Bhabha Exams clearly show a move toward real-world science application and concept-based testing.
Students with strong fundamentals, consistent practice, and logical reasoning easily cross 90+ marks.
🎯 “It’s not about memorizing answers — it’s about understanding how science works.”
