NEET Deleted Syllabus: The National Medical Commission (NMC) has officially released the NEET UG 2025 syllabus on its website, nmc.org.in. However, the syllabus for 2025 has not undergone significant changes, and it is available for download.
Further, the NMC has made revisions to the NEET UG 2025 syllabus by removing, adding, and modifying certain topics and chapters in the subjects of physics, chemistry, and biology. Meanwhile, the streamlined syllabus emphasizes essential areas to assist candidates in their preparation for the medical entrance examination. Additionally, it provides chapter-wise weightage, indicating the significance of each topic for achieving high scores. Candidates can access the NTA NEET 2025 syllabus PDF for further information, including details on the topics that have been removed and other relevant updates in the comprehensive article.
The NMC has unveiled the reduced syllabus for NEET 2025, encompassing physics, chemistry as well as biology. Likewise, candidates preparing for the medical entrance examination can consult the table below for information on the deleted topics. The date for the NEET 2025 exam will be announced by the NTA.
