In order to get Good NIT's through JEE mains, yu have to score around 96-98 percentile score in JEE mains and the equivalent rank can be within 40k for SC category in order to get Good colleges through JEE Mains.

Further, the above is only a prediction as the JEE mains cutoff keep varying every year and it depends on various factors like : difficulty level of the paper, previous year Cutoff trends, number of aspirants appearing, etc.
