Dear aspirant,

As you have mentioned that you have secured a rank of 2.7k rank in wbjee so let me tell it's a bit difficult to predict what would be the exact situation at the mop up round.

Various factors are considered while deciding the cut offs like number of candidates appearing in the counselling, number of vacant seats in college, previous years cut offs and difficulty level of the paper. You can expect a decent branch in iem.
