Hey,

In josaa counseling categories rank is considered, if you belongs to obc-ncl categories then your category rank is considered in josaa counseling. You can get Nit colleges on the basis of their categories rank in josaa counseling. But when you go through csab counseling then your crl rank is considered and on the basis of crl rank you will get a seat in csab counseling.

If you have good categories ranks then definitely you will get good Nits.

Here I'm mentioning some links for jee main predictor by which you can predict your college on the basis of your rank.

Hope you will get it.

Thank you!
