Students preparing for NEET 2026 understand that Biology can make or break their medical entrance dreams. Covering 90 questions worth 360 marks, Biology makes up 50% of the total NEET score — an edge every candidate must maximize. Yet not all chapters carry the same weightage. Some consistently yield more questions and higher scores, making them priorities for focused preparation.

Here’s the data-driven approach every aspirant needs:

1. Human Physiology — 20% (18–20 questions)

This chapter is the backbone of NEET Biology, yielding roughly 80 marks. Its high weightage makes it a must‑master for every aspirant.

2. Genetics and Evolution — 18% (16–18 questions)

Genetics demands conceptual clarity and problem‑solving skills. It’s a differentiator for top scorers — a priority chapter yielding roughly 72 marks.

3. Diversity in the Living World — 14% (12–14 questions)

Direct factual questions dominate this chapter, making it ideal for memorization. Expect roughly 48–56 marks from this area.

4. Ecology and Environment — 12% (10–12 questions)

Combines theoretical knowledge with current environmental concerns. Mastering this chapter can secure 40–48 marks.

5. Structural Organisation in Animals and Plants — 9% (8–9 questions)

Foundational knowledge for understanding complex physiological processes. Expect roughly 32–36 marks.

6. Human Reproduction — 9% (7–9 questions)

A highly focused chapter yielding 28–36 marks, making it ideal for intensive preparation.

7. Plant Physiology — 6% (5–6 questions)

Tests deep conceptual understanding. This chapter can secure roughly 20–24 marks.

8. Cell Structure and Function — 5% (4–5 questions)

Although lower in weightage, it forms the foundation for many chapters. Expect roughly 16–20 marks.

9. Biology and Human Welfare — 4% (3–4 questions)

Connects biology with human health and disease, yielding roughly 12–16 marks.

10. Biotechnology and Its Applications — 3% (2–3 questions)

Modern and relevant, this chapter can secure roughly 8–12 marks. Its focused scope allows for quick, targeted preparation.
