NEET 2022 Physics Syllabus For Class 11th 

This page is providing  Physics Syllabus For Class 11th of year 2022. Read carefully to get it right preparation for NEET 2022 in Physics class 11th.

For National Eligibility-cum-Entrance Test NEET (UG)-2022, 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 CBSE, NCERT, and COBSE. 

This is to establish uniformity across the country, keeping in view the relevance of different areas in medical education.
