NEET 2025 Brings Major Syllabus – The National Eligibility cum Entrance Test (NEET) 2025 is set to undergo one of its most significant transformations to date. The National Testing Agency (NTA) has officially announced major revisions in the Chemistry and Biology syllabi for NEET 2025, with the new format coming into effect from August 15, 2025. This update, as per NMC’s latest curriculum rationalization, aims to reduce academic burden, align NEET with the National Education Policy (NEP) 2020, and standardize content with NCERT textbooks.
These changes have sparked nationwide discussions among students, parents, teachers, and coaching institutes. The modifications are not limited to merely shuffling topics—they include full topic deletions, restructuring of important chapters, and clarity on what will no longer be asked in the competitive exam. Candidates appearing in NEET 2025 must thoroughly familiarize themselves with the updated syllabus to avoid studying outdated or irrelevant material.
With Biology contributing 50% of the total questions in NEET and Chemistry forming a critical component, understanding these updates is vital for every aspirant. Additionally, a few exam pattern updates regarding weightage and section divisions have also been hinted at, making it more important than ever for candidates to adapt their preparation strategies.
Below is a detailed breakdown of the syllabus updates, deleted topics, updated blueprint, and what students must do to succeed under the new format.
