JEE Main is being conducted twice ( Jan & April) in a year by NTA, You can apppear both of the session, The best attempt will be considered for the admission.

Based on your score your probable rank will be 580,134 - 645,134. The chances are very less to be eligible for JEE Advance so I would suggest you to appear for JEE Main April session & try to score well to scure a seat in NITs.

NOTE: Rank Predicted is on the basis of the expected total number of students i.e. 1152650 appearing in the JEE Mains April Session.

Good Luck!
