Hello aspirant, 

Well usually the cutoffs for BAMS colleges is:

420+ for government college 

360+ for semi government college 

119-280 for private colleges 

(for general category students)

So if you belong to general category it might be a difficult task. 

Well this score may vary for different institutions. Also some colleges conduct a separate entrance exam or give admission on the basis of 10+2 score. 

Hope it helps 

Thank you
