You haven't mention your course of which you have applied please specify that you get your answers more accurate.moreover, the selection is based on your entrance rank, let me tell you there are fixed number of seats for all the courses so you need to secure a good rank to get admission.there are more than 500 seats in each course and 30 seats in bsc particular branch each so you need to under rank 500 to get admission there.but sometimes students leave the course because they are selected somewhere else so there is chance that rank may increase.
