NIT Rourkela is listed in top NITs and cuttoff for that is very high.According to Your Marks that is 120 marks your rank will be approx 70000-80000 and the closing rank for NIT Rourkela is arround 17000-18000 for the branches like bio technology or bio medical..
For home quota it may extend for some rank but it go only upto 20000 not more than that.
