Expected Number of Questions From NCERT in NEET 2025

Why is NCERT Important for NEET?

NCERT books are considered the best books to prepare for NEET because they:

• Include All Subjects in the Syllabus: NCERT properly follows the NEET syllabus designed by NTA. You won't miss a single important topic.
• Simple and Easy Language: Concepts are made simple and easy to understand and remember - especially helpful for Biology, Physics, and Chemistry.
• High Relevance to NEET: Most of the NEET questions (particularly in Biology) are directly or indirectly taken from NCERT lines, diagrams, or solved examples.
• Concise and Focused: No unnecessary or redundant information - this keeps you on target and saves time while revising.
• Strong Conceptual Base: NCERT develops your fundamental concepts, which is crucial to resolve tricky application-based NEET questions.
• Key Diagrams and Tables: Most NEET Biology questions are derived from NCERT diagrams, labels, and tables - these need to be memorised.
• Safe for Direct Q&A: Certain Physics and Chemistry numerical values and routine results are copied word-to-word from NCERT - accuracy is a must.
• Ideal for Last-Minute Revision: NCERT books are ideal for quick and thorough revision in the last couple of days leading up to the exam.
