Hello Devi,

Cutoffs are decided by the number of seats available, number of students applying for the seats , difficulty level of the paper, previous year cutoff trends,the state you belong to  etc.For general category students the to get government seat, the score should be minimum 450+. In your case since you are an SC candidate , it should be lesser than this . Your predicted percentile would be around 85.16 - 85.66 and the rank would be 205727 - 245877 . Hence, based on the previous cutoff trends , 300 to 340+ can be considered as a safe score.It may slightly vary depending on the factors mentioned above but do not worry , you seem to have a decent chance for govt. seat. Also when it comes to private colleges,  100-200+ is enough for good private BHMS seats.
