🔍 Key Observations from 20 Years of NEET Papers
-
1. Most Repeated Topics:
- Human Physiology (14 Q/year) → Nephron, ECG, Hormones.
- Genetics (12 Q/year) → Mendel's laws, DNA replication.
- Ecology (7 Q/year) → Energy flow, Greenhouse effect.
-
2. NCERT Dependency:
- 90% of questions are directly from NCERT diagrams/text.
- Examples:
- 2024: Diagram of Nephron (Excretion).
- 2023: Lac operon (Genetics).
-
3. Cyclic Trends:
- Photosynthesis (C4 pathway) → Appears every 2–3 years.
- Animal Kingdom (Non-chordates) → 2020, 2023.
-
4. High-Yield Diagrams:
- Chloroplast (5 times in 10 years).
- Brain parts (4 times).
🚀 Final Strategy for NEET 2025
-
1. Priority Order:
- Human Physiology > Genetics > Plant Physiology > Ecology.
-
2. Must-Revise Topics:
- 5+ questions/year: Nephron, Photosynthesis, Mendel's laws.
- 3–4 questions/year: Biomolecules, Ecosystem, Microbes.
-
3. Avoid Low-Yield Topics:
- <1 question/year: Lichens, Frog morphology.
