Most students preparing for NEET study the entire syllabus equally. Big mistake.
Some chapters are worth 9% of your marks. Others? Less than 1%. Spending equal time on both is like making a foul to give penalties in football, completely self-inflicted!
The good news? Understanding NEET 11th and 12th weightage lets you study smarter, not just harder. You can allocate your time proportionally and hit maximum marks with minimum effort.
This is exactly what NEET toppers do. It’s not rocket science, it’s just strategy. Now, let’s look at NEET 11th and 12th weightage.
How Are Marks Distributed Between Class 11 and Class 12?
Class 11 and Class 12 are not weighted in the same way, as most of the coaching centres say. Based on the NEET analysis that has been done within the past three years, the weight of NEET in the 11th and 12th is at about 45 per cent and 55 per cent, respectively.
This has been a similar distribution over the past years, see Class 12 having a little higher weightage in comparison with Class 11.
| Subject | Class 11 Questions | Class 12 Questions | Total Questions | Total Marks |
| Physics | 20–21 | 24–25 | 45 | 180 |
| Chemistry | 19–21 | 24–26 | 45 | 180 |
| Biology (Zoology + Botany) | 44 | 46 | 90 | 360 |
| Total | 85 | 95 | 180 | 720 |
Chapter Wise Weightage for NEET 11
Class 11 may have fewer questions, though it includes some of the groundwork chapters that are repeated in several units. What makes them expensive to leave unaddressed is that some Class 12 topics are directly based on these foundations. The plan here is obvious: master the basics, not just surface-level knowledge. Let’s look at the chapter wise weightage for NEET 11 for each subject.

Conclusion
NEET 11th and 12th weightage isn’t just numbers; it’s a smart study roadmap. The high achievers do not just study a lot; they study what is important. Pay a lot of emphasis on high weight age parts, keep the level of preparation constant on medium weight age parts, and do not neglect low weight age parts.
Apply NEET 11th and 12th weightage to use time efficiently, score 80-90 per cent in high-weightage subjects, and use your limited time in activities that have the highest effect.
FAQs
Q: Is Class 11 or Class 12 more important for NEET?
Both matter, but Class 12 has slightly higher weightage. Still, Class 11 builds the base for many Class 12 topics. Don’t treat it as revision; study both smartly, guided by NEET 11th and 12th weightage.
Q: Which Biology chapters have the highest weightage in NEET?
The Biology chapters with high weightage include Cell Cycle & Cell Division, and Genetics. Along with Human Physiology topics, they together contribute a large chunk of Biology marks and should be a top priority.
Q: Can I skip low-weightage chapters like The Living World or Neural Coordination?
Skipping completely is risky. Even low-weightage chapters can fetch 1–2 questions. Study them lightly; they act as score insurance.
