Hello Yuvraj,

With a rank of 37,616 and category rank as 9390 you might not get NIT Raipur if you are not using a state quota. In 2018 in CSE the closing rank for general rank(with state quota) was 25196 and OBC rank(with state quota) was 12740. So you could get a CSE seat with OBC category rank and state quota. 

But without state quota the closing rank of general was around 12k and for OBC it was around 7k for CSE. So on the basis of 2018's data you can get into NIT Raipur with CS if you use your state quota and OBC rank. 

All the best.
