NEET Key Chapters You Can’t Afford to Miss

Understanding the key NEET chapters and the weight assigned to each chapter is crucial for passing the test. Now that you have a list of the key NEET chapters, you can concentrate more on them. You may determine chapter wise weightage and, therefore, more weight in the NEET exam by using the chapter-by-chapter weighting system. Therefore, avoid making the error of undervaluing or disregarding any of these crucial NEET chapters.

Chapter Weightage for NEET

Here is the chapter wise weightage on every subject for NEET. From this, you can determine which chapters are the most important. You can’t afford to miss those chapters.

1.   Chapter Wise Weightage for Biology

The Biology part accounts for 360 points or half of the 720 total points awarded on the NEET test. To further simplify, the 90 questions in the Biology part are divided into 45 questions about Botany and another 45 questions about Zoology.

Botany

Must-do Chapters	Low Weightage Chapters
Genetics and Evolution (25%)	Morphology of Flowering Plants (7%)
Ecology and Environment (16%)	Plant Anatomy (4%)
Plant Physiology (14%)	Bio-molecule (3%)

2.   Chapter Wise Weightage for Physics

In the case of chapter wise weightage, the most crucial chapters in this area include Thermodynamics, Current Electricity, Laws of Motion, The System of Particles and Rigid Bodies, and the Magnetic Effect of Current & Magnetism. Experts suggest devoting additional time to these chapters.   A candidate must concentrate on answering numerical-based problems in addition to learning from NCERT and other reference materials if they want to receive high results in physics. The NEET chapter-by-chapter weighting for Physics is displayed in the table below.

Must-do Chapters	Low Weightage Chapters
Laws of Motion (5%)	Centre of Mass (System of Particles and Rotational Motion) (2%)

Effective Preparation Strategy for NEET

Understanding the chapter weightage for NEET is just the beginning; having a clear action plan is crucial. Here’s a concise five-step strategy to guide your preparation:

1.   Prioritize Conceptual Understanding

Many students fall into the trap of memorizing formulas, which may work for some topics. However, NEET focuses heavily on concept-driven questions. Ensure that you grasp the underlying principles behind each formula. By solidifying your understanding of key concepts across major topics, you will establish a strong foundation early on.

2.   Identify Weaknesses Early

It’s important to pinpoint your areas of weakness as soon as possible. If you find certain chapters particularly challenging, don’t hesitate to seek assistance from teachers, and classmates, or even consider enrolling in a coaching program or online study group. Participating in mock tests can also help reveal these weak spots, allowing you to focus on them and minimize challenges during the exam.

3.   Take Regular Mock Tests and Analyze PYQs

Engaging in mock exams and reviewing previous years’ question papers (PYQs) is critical for success in NEET. These practices will enhance your speed, familiarize you with the exam format, and simulate real exam conditions. Analyzing PYQs will help you identify commonly tested subjects and question patterns. Ensure you take timed mock exams and review the results to identify areas for improvement.

4.   Manage Your Time and Revise Regularly

Create a study schedule that allocates ample time for revising critical chapters. Practicing previous years’ question papers and taking mock exams will help you develop effective time management skills for the actual test. Learning to manage your time efficiently during the exam, in addition to knowing the chapter weightage, is vital for success.

5.   Practice Diverse Problem Types

Your preparation should include tackling a range of problems with varying levels of difficulty. Especially for Biology and other subjects, consistent practice is key. While it’s important to master simpler problems, make sure to challenge yourself with complex questions that integrate multiple concepts.
