Hello,

It would be difficult to tell you the exact about the qualify marks & admission possibilities as JEE Main is being conducted twice by NTA, and NTA Scores for both of the attempts will be taken into consideration and the best of the two attempts will be considered for ranking purposes.

Based on your score, your probable rank will be 290,928 - 330,928. 

NOTE: The Overall Rank Predicted is on the basis of the expected total number of students i.e. 1152650 appearing in the JEE Mains 2019.

Based on this score the chances seems less to get a seat in NITs, IIITs, GFTIs. You can also prefer the given below link to check the previous year cutoff of NITs, IIITs, GFTIs.
