Dear,

This is not your actual rank. The vacant seats reserved for SC, ST candidates which do not get filled during counselling will be alloted to candidates of respective categories for admission into a preparatory course. In this preparatory course you will be prepared and trained in the respective institute for 1 year and after that you will be declared as pass or fail according to which you will get a direct admission in ug course of that institute from the next year.

So, rank you have is different from the normal rank everyone usually gets! Hope it helps! Good luck!
