Hi aspirant, since you have 34342 rank as your SC category rank so based on this let me clear you this thing that the cut off for SC as per AIR is approx 60000 but since you have 34342 rank as your SC category rank not AIR so it is not possible for you to get into the University but no need to feel low about this you can definitely try for other good colleges for this you may use Careers360 college predictor tool;
