I see that you want to do BTech from CSE or EEE in NIT Rourkela. It's a good choice. 

But now everything depends on your rank how much rank you get. And are you eligible or not. You must have specified your category and whether you are hs or os.

I will take that you are general category and os.  Previous year closing rank in round 7 for CSE was around 3600 and that for EEE was around 9000.  So see this rank. If you are under this rank then you will get a seat in NIT Rourkela. If not , then try for other colleges or change your branch. 

Hope it helps.

Thank you.
