Hi Vaibhavi,

For NIT Rourkela, homestate quota, considering the previous year's cut offs, food processing engineering closes at the highest rank of 52k followed by bio medical engineering at 48k. Whereas computer science closes at the least of 8k. 

So, if you want to have a seat in less famous branches, it is ok even if your rank is around 45k.

But if you want to have a seat in popular branches, make sure your rank is around 5k.

All the best
