Last 60-Day Strategy Using NEET 2026 Chapter Weightage
With limited time before NEET 2026, aspirants should focus on chapters contributing nearly 60–70% of the paper. Prioritising high-weightage topics first, followed by medium-weightage chapters, ensures better score optimisation.
A structured revision plan including daily MCQ practice, weekly mock tests, and error analysis can significantly improve performance in the final months.
Focus first on chapters contributing the highest weightage in Biology, followed by high-return topics in Chemistry and scoring chapters in Physics. Avoid starting new low-weightage chapters during the final 30 days unless fundamentals are already strong.
How to Use NEET Chapter-Wise Weightage to Study Smart
Using NEET 2026 chapter-wise weightage correctly helps aspirants focus on high-scoring areas and avoid wasting time on low-return chapters.
Start preparation with NEET 2026 high-weightage chapters from Physics, Chemistry, and Biology
Give more revision cycles (3-4 times) to chapters that appear frequently in NEET
Use NEET previous year questions to understand how important topics are asked
Allocate study time based on weightage, difficulty level, and personal strengths
Practise NEET 2026 MCQs and numericals daily from high-impact chapters
Keep low-weightage chapters for final revision, not initial preparation
Revise NCERT diagrams, tables, and definitions for Biology and Inorganic Chemistry
Use mock tests to evaluate chapter-wise performance and adjust your study plan
Following a weightage-based strategy allows aspirants to study efficiently, improve accuracy, and maximise their NEET 2026 score.
Frequently Asked Questions (FAQs)
Q: Which subject has the highest weightage in NEET 2026?
A:
Biology has the highest weightage in NEET 2026, contributing 360 marks out of 720. Due to its NCERT-based questions and repeated topics, Biology is considered the most scoring subject for NEET aspirants.
Q: Should I prepare only high-weightage chapters for NEET 2026?
A:
While high-weightage chapters should be prioritised, low-weightage chapters should not be ignored completely. Once important chapters are well prepared, low-weightage topics can be revised to avoid losing easy marks.
Q: How many times should I revise high-weightage chapters before NEET?
A:
High-weightage chapters should be revised at least 3-4 times before the NEET exam. Regular revision, along with PYQ practice and mock tests, helps improve accuracy and long-term retention.
Q: Is NEET 2026 chapter weightage officially released by NTA?
A:
NTA does not release official chapter-wise weightage. The analysis is based on previous year question trends and subject-wise question distribution.
Q: Which chapters contribute 60–70% of NEET paper?
A:
High-weightage chapters from Biology such as Molecular Basis of Inheritance, Biotechnology, and Human Health & Disease, along with key chapters from Physics and Chemistry, together contribute nearly 60–70% of the total questions.
