NEET Exam 2025 Topics with Solutions: Is the NEET syllabus vast and time for preparation less? Well, many fail to complete the syllabus on time, and the reasons can be manifold. In such cases, one can resort to covering the high-weightage chapters, i.e., NEET important topics and then move on to the low-weightage chapters. These topics have a higher chance of appearing in the exam, helping you fetch good marks.
You can also create a study plan based on the weightage of chapters in NEET. A well-articulated study plan will help you cover the NEET syllabus based on what is more important, and you will also be able to manage time effectively. Dive into the article to know the subject-wise Important Chapters for NEET, the Weightage of Chapters in NEET, and more.
