Preparing for the National Eligibility cum Entrance Test (NEET UG) without an intimate knowledge of the official syllabus is like setting sail without a compass.
Every year, over 24 lakh medical aspirants compete for approximately 1.05 lakh MBBS seats across government and private medical colleges in India. With competition intensifying and cutoff scores pushing higher, smart syllabus prioritization is the single biggest factor separating qualifiers from top rankers.
The NEET examination is conducted by the National Testing Agency (NTA) based on the medical curriculum prescribed by the National Medical Commission (NMC). The syllabus covers the core disciplines of Physics, Chemistry, and Biology (Botany & Zoology) across Classes 11 and 12.
This comprehensive guide details the complete, officially updated NEET subject-wise syllabus, chapter-wise weightage, exam pattern, and high-yield scoring priorities.

Frequently Asked Questions (FAQs)
Are state board textbooks enough, or is NCERT mandatory for NEET?
NCERT is strictly mandatory. More than 90% of questions in Biology and Inorganic Chemistry are framed word-for-word from NCERT textbooks. State board books can be used for extra numerical practice, but NCERT is the ultimate reference.
Did NTA delete topics from the NEET syllabus?
Yes, the NMC rationalized the NEET syllabus to align with the rationalized NCERT textbooks. Several rote-heavy chapters (like Solid State, Metallurgy, Surface Chemistry, States of Matter, Digestion and Absorption, Reproduction in Organisms) were removed, while specific practical skills were emphasized.
How much weightage is given to Class 11 vs. Class 12?
The distribution is almost evenly balanced:
- Class 11 Syllabus: Approximately 48% to 50%
- Class 12 Syllabus: Approximately 50% to 52% Do not neglect Class 11, as foundational chapters like Mechanics, GOC, Chemical Bonding, and Cell Biology form the building blocks for Class 12.
