hello, 

first of all i would like to bring this to your notice that private colleges donot participate in all India quota counselling. these do participate in the state counselling. you have not mentioned any specific college. so its difficult to come up with any information. cutoffs are subject to change. these vary from college to college. 

keeping the genral trends in mind and just to give you an idea, its always better to score 350+, even if you are an sc candidate. since the cutoffs are unpredictable. this year the cutoffs have gone way higher than before. 

neet 1st round of  ouncelling is already done. the se ond round of counselling is about to hault. the last phase of  ouncelling is the mop up round. as of now make sure that you keep yourself updated about all the necessary information regarding counselling schedule. 

good luck

good luck
