Cracking NEET requires two things:
- Knowing what to study, and
- Knowing what to study more.
That’s where chapter-wise weightage becomes a game-changer. While NEET follows the complete NCERT syllabus, some chapters consistently carry higher weightage, contain easier questions, or are simply more scoring.
Here is an easy-to-understand, subject-wise breakdown of the most scoring chapters in Biology, Physics, and Chemistry — based on trends from the last 10+ years of NEET papers.
✅ Biology Weightage (Zoology + Botany)
The most crucial subject — 90 questions, highest scoring, and heavily NCERT-based.
Since Biology accounts for 50% of NEET, mastering the right chapters dramatically boosts your score.
