Now a days many colleges are accepting the JEE main marks as a certificate of giving admission, so you will get a college for sure .

If your rank seems to be quite good to get a seat in a government college. Kindly wait till the last round and do the counselling wisely.

I also wanted you to see the previous year cut off ranks of different nit and other colleges so you can make your prediction much better . Kindly take wise decision.

If you are a fresher kindly wait a year I am sure you will get a IIT next year .

Hey,
Yes, you can definitely get them. As it is easier as compared to IITs and NITs. But it all depends upon your marks in the exam.
Thank you.

Yes you can for that you will need only board marks and they are very easiy to get as compared to NIT or IIT etc.
