Studying everything equally is one of the most common and costly mistakes NEET aspirants make. Not all chapters carry the same weight — and knowing which ones do is the difference between a scattered preparation and a laser-focused one. This guide gives you the complete NEET 2026 syllabus with chapter-wise weightage for Physics, Chemistry, and Biology — based on analysis of the last 10 years of NEET papers. NTA has confirmed that the Re-NEET 2026 syllabus is unchanged. Combine this with the 5-Week Re-NEET 2026 Study Plan to build a preparation strategy grounded in data.
