NCERT textbooks act as the base to complete the syllabus and develop conceptual clarity and understanding of the topics and chapters. However, for practice purposes, students may refer to other books and resources as well. It is advised that while starting the NEET preparation, candidates refer to the NCERT books and move towards other books and advanced resources after that.

How to Prepare for NEET 2026 Chapter-wise Weightage?
While students are primarily advised to complete the NEET syllabus thoroughly, the next level would include the proper allocation of time, energy and resources to focus on the high weightage topics of NEET. To achieve that, experts suggest the following tips:
- Compare previous years' NEET question papers: Make a list of topics which were covered in each subject for the past five to six years. This will give you an idea of the NEET chapters with high weightage over a consistent period. Prioritise those topics while preparing.
- Take sectional mock tests: Students are advised to take full-length mock tests once they complete the entire syllabus of NEET 2026. But to gain expertise over these areas, taking section-wise NEET mock tests comes in handy as it gives exposure to varied question types. Moreover, after each sectional mock test, they should get it analysed by their teachers to understand and mitigate common mistakes, as well as deduce a more effective question-solving method.
- Select the right Books: While there are a plethora of NEET books available, one must select those which have quality content with the latest syllabus, proper description and explanation as well as practice questions.
- Regular revision: Regular revision is the key to any exam preparation. To ace NEET chapters with high weightage, students must regularly revise those topics and solve as many questions as possible so that they do not go out of touch with these areas.
Now that students are aware of the high-weightage chapters for NEET 2026, it is time to devise the preparation strategy in terms of time to be allotted for each section, practice, revision, etc. While taking NEET mock tests or solving previous year question papers, they should decide on the test-taking strategy. Based on the chapter-wise weightage for NEET, aspirants can decide which questions to attempt and which to skip. However, students must note that the chapter-wise weightage for NEET provided above is based on last year and this year, it may not be the same. Hence, they should be prepared for every possibility.
In India, only NEET is the entrance test for admission in undergraduate medical courses in India. All of the top medical institutes in India, including AIIMS and JIPMER, will consider the NEET 2026 score. With such a high level of competition, and only those who have prepared for the examination seriously can clear it. Being the only way of getting admission to MBBS/ BDS and other medical and paramedical courses in India, the need to stay focused has increased. Moreover, with the removal of the upper age limit from the NEET eligibility criteria. The exam is even more competitive. In order to clear the NEET 2026 exam, students must work with a very strong NEET preparation strategy so that they can stay motivated throughout the preparation phase.
