NEET 2025 Physics Weightage by NTA - PDF Download

NEET 2025 Physics Weightage: NEET stands for National Eligibility Entrance Test, is a qualifying examination for admission in medical courses such as MBBS & BDS in various medical and dental institutes in India. The National Testing Agency (NTA) administers this exam.

In order to apply for NEET 2025, you must have opted for the science stream in your 11th & 12th class. In particular, you must have passed Physics, Chemistry & Biology / Biotechnology as your compulsory subjects in your 11th & 12th class. Prior knowledge of the syllabus of each subject helps in preparing well for the NEET exam. NEET Physics section has always been considered as one of the most difficult sections of NEET exams by candidates due to the fact that it requires conceptual clarity and a good knowledge of the concepts of physics to apply the knowledge gained on numerical based questions. It is often said that this section is difficult as long as it requires calculations and reasoning. However, when you focus on the topics according to their importance analyzed from the previous trends, Physics becomes a cakewalk on the exam day. To help you in the same process, we have provided you the chapter-wise weightage for NEET Physics.
