# NEET 2024 Physics Syllabus Updated

(Higher Secondary Stage)

NEET (National Eligibility cum Entrance Test) Physics Syllabus for the medical entrance examination. Physics NEET Syllabus will help candidates to prepare for the exam thoroughly and to score more marks in NEET Examination. The syllabus is the most significant part as it aids all the candidates to know about the various topics/subjects on which they must work upon for the examination.

The National Medical Commission of India (NMC) recommends the following syllabus for admission to MBBS/BDS/BAMS/BSMS/BUMS/BHMS courses across the country, after review of various State syllabi as well as those prepared by NCERT, and COBSE (Council of Boards of School Education in India). NEET Physics Syllabus covers topics of both classes 11 and 12.
