Hi, you cannot get all the NIT, IIIT , GFTI at a time you can avail any one. Now on the basis of your ST category rank i.e. 5947 you can definately get into NIT and IIIT. As well as you can also opt your desired branch in your chosen college. Let me tell you that you may get into NIT, Tadepalligudem with this rank as it's cutoff of previous in ST- Female in CSE  was 1016, for ECE it was 1759 and for IT it was may be under 2000 approx.
