Neet cutoff for bpt course 2025

The admission process and cutoff scores for the Bachelor of Physiotherapy (BPT) course in 2025 are distinct from those of MBBS and BDS, for which NEET is the primary entrance exam. While some BPT colleges might consider NEET scores, it is generally not the mandatory entrance examination for all BPT admissions across India.

The admission criteria for BPT courses typically involve your marks in the Class 12th board examinations, with Physics, Chemistry, and Biology as the main subjects. Many colleges admit students based on merit, considering the aggregate marks obtained in these subjects. A minimum aggregate score of 50% in PCB is a common eligibility criterion, although this can vary slightly between institutions. Some colleges might offer a relaxation of 5% for reserved categories like OBC, SC, and ST.

However, it's important to note that some universities and states do conduct their own entrance examinations for BPT admissions. Additionally, a few private colleges might consider NEET scores as part of their admission process, although it's usually not the sole criterion. State-level entrance exams might also be relevant for admissions to BPT colleges within a particular state. For example, in Maharashtra, the Maharashtra Common Entrance Test (MHT CET) has been used for BPT admissions.

Therefore, to ascertain the specific cutoff for a BPT course in 2025, you need to identify the particular colleges you are interested in. Then, you should check their individual admission criteria, which will be available on their official websites or admission brochures. These sources will provide the most accurate information regarding whether they consider NEET scores, conduct their own entrance tests, or admit students based solely on their Class 12th marks and the required cutoff percentages. Keep an eye on the admission notifications of your preferred colleges for the most up-to-date details.
