Master these high-weightage Do or Die chapters to score 340+ in NEET Biology. Complete analysis of most important chapters with guaranteed questions every year.
Remember these points for your NEET preparation
Not all chapters are created equal in NEET. Some chapters consistently contribute 8-10 questions while others give just 1-2. This guide identifies the "Do or Die" chapters that you MUST master to score 340+ in Biology.
| Criteria | Importance |
|---|---|
| High Weightage | 5+ questions every year |
| Predictable Pattern | Similar questions repeated |
| NCERT-Heavy | Direct questions from textbook |
| Scoring Potential | Easy to moderate difficulty |
| Time Efficiency | High marks for time invested |
These chapters give 35-40 questions EVERY year. Missing these = missing NEET.
Why It's Do or Die:
Must-Know Topics:
| Topic | Question Type | Difficulty |
|---|---|---|
| Mendel's Laws | Ratios, Crosses | Easy |

"Focus on the 15 Do or Die chapters for first 80% of your preparation. The remaining 20% time can cover everything else. This ensures you never score below 300 in Biology." — Dr. Shekhar, AIIMS Faculty
| Mastery Level | Expected Score |
|---|---|
| All 15 chapters mastered | 320-350 |
| 10 chapters mastered | 260-290 |
| 5 chapters mastered | 180-220 |
These chapters contribute 70-75 questions. Mastering them guarantees 280-300 marks. For 340+, you need basic coverage of remaining chapters too, but priority should be these 15.
Start with Human Physiology - it's the largest contributor and relatively easy to understand. Then move to Genetics.
For these 15 chapters, study NCERT line by line. Every sentence can become a question. Don't skip any example or diagram.
Genetics is non-negotiable for NEET. Take extra time, solve 100+ numericals, watch video explanations. It's worth the investment.
