Hi, 

As per your score there is some chance for you to get a seat in government bams. Till last year a score above 300 was considered good for getting into bams. Your's is bit higher. Wait for the BAMS counselling to begin and see what comes up. Also you can get a seat in different state. But you need to be updated about admission procedure in those colleges in the respective state. So go through their websites on a regular basis. Hope for the best. 

Good Luck!
