It would be difficult to predict the exact qualifying marks or rank and admission possibilities as JEE Main is being conducted twice by NTA for the first time and rank will be based on NTA percentile score which will be decleared in the month of April.
Based on this score Your probable rank will be 91,295 - 98,795, With this rank the chances are less to get the core branches in NITs.
I would suggest you to appear for April Session & try to score well to get into your desired NIT & branch and To get admission in Government colleges of West Bengal you can apply for the state level entrance Exam of West Bengal (WBJEE) if you belong to West Bengal.
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!
