NEET Deleted Syllabus 2025: Subject-Wise Deleted Topics and Chapters

The NEET Deleted Syllabus 2025 comprises topics from chapters such as Kinematics, Rotational Motion, Laws of Motion, Thermodynamics, etc. The deleted topics are taken from all three sections of Physics, Chemistry, and Biology in the NEET syllabus 2025. 

The NEET Deleted Syllabus 2025 comprises the list of topics that have been reduced by the National Medical Commission (NMC) in the revised syllabus of NEET UG. The changes in the entrance exam syllabus were introduced in 2024 to meet the demands of the changing times. Several topics from the chapters like Kinematics, Rotational Motion, Laws of Motion, Thermodynamics, and many more have been removed in the NEET reduced syllabus 2025.

The NEET 2025 Exam is set to be conducted on May 4, 2025. While there have been no major changes in the NEET Syllabus 2025 PDF, the chapters previously removed in the reduced syllabus from Physics, Chemistry, and Biology remain unchanged. To balance out the exam curriculum, a few major topics were also included in the previous year’s syllabus. Read the article further for an in-depth discussion on the revised syllabus for the upcoming NEET exam.
