Dear Khushvi 

Generally NEET isn't used as the point of entry to bachelors in Physiotherapy (BPT) courses, however it will highly depend upon the college/state you are seeking admission in. For admissions to Bachelors in Physiotherapy courses, every college/state/university have their own rules. In most cases, the admission in BPT is done through different state level and university level entrance examinations. For instance, Indraprastha university conducts takes admission to Bachelors in Physiotherapy course through a Common Entrance Test (CET). In fact, there are some colleges/universities, which do not take admission to Bachelors in Physiotherapy through any entrance exam, rather only consider Class 12 marks, for instance Manipal University, et. al. 

If you are particularly talking about the state of Maharshtra, then yes. NEET UG 2018 marks and All India Rank will be used for admission to all health sciences courses in Maharshtra, including B.P.Th (Bachelors in Physiotherapy). Although, it wil not cover Deemed universities in Maharshtra under its perview, which means that they might conduct their own entrance exam for B.P.Th admission.

I advise you to check the web portal of the particular college you are seeking admission in. Besides this, check the link given below to see the notification released by DMER with regards to 2018 B.P.Th. admissions.
