Hey,
You should always aim to score high in your 12th because all the good colleges require good percentage. However,for Scheduled Caste the percentage required is less as compared to Unreserved category which can be as low as 80-85 percent(for first cutoff) or less depending upon the course. The University declares around five to six cutoffs every year.
