Hello Raymon,

JEE Main is being conducted twice by NTA for the first time so it is difficult to predict about the admission possibilities 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.

However As per the previous year, The Closing rank was around 30322 for CSE branch other state quota as a General Category. You can check the other branches cutoff with the given below link.
