Hello Pankaj,

It would be difficult to tell you the exact as JEE MAin is being conducted twice by NTA for the first time. Based on your score, You might have the chance to get NIT Patna but chances seems less to get the core branches. You can also use JEE Main college Predictor tool to know your other chances.
