NEET CLASS XIIth/XIth 2021 UPDATED SYLLABUS OR DELETED ITEMS IN SYLLABUS !! (PDF ALSO GIVEN).
As we all know about covid-19 pandemic it creates a total destruction and mess for the education system, economy and many more things !!
As students are unable to take classes or proper tuitions or we can say due to lack of resources because of covid-19 they are unable to prepare a huge amount of syllabus in a short span of time without help of anyone !!
So Authorities decided to reduce the syllabus of NEET-2021,so that student can't feel a burden of doing a huge amount of syllabus without any proper guidance as coaching and institutions are also closed !!
So Today We Are Going To Update You Through The Updated Syllabus Of NEET 2021 -
Physics Updated Syllabus 2021 (PDF Also Given)
