The Union HRD Minister did announce that the NEET syllabus for 2021 will be reduced as the academic year is going to be relatively lesser. While we do not know the exact syllabus, what we can suggest is prepare from NCERT books until the syllabus is officially released. It might be either released in December along with the online registration forms for NEET 2021 or it might be even released earlier. We need to wait to hear from either NTA or MHRD. Rest is all speculation.
