Hello aspirant.

With 318 marks, there are very few chances for you to grab a seat in private BAMS colleges through government quota as they require at least 550+ marks, even with reservation.

However, you might be able to get a seat in the following deemed Ayurveda colleges-

1. DY Patil Ayurveda College, Pune

2. Bharti Vidyapeeth College of Ayurveda, Pune

3. Mahatma Gandhi Ayurved College, Wardha

4. Padamshri DY Patil Ayurveda College, Navi Mumbai
