Yes, HODs do teach in droppers batch. There are four houses in dropper coarse V,X,Y,W . V house consist of students who have completed their 12th from Vibrant Academy and X house consists of students who have completed their 12th from various other coaching institutes. While Y and W mostly consist of students who are preparing for the very first time for the JEE .

HODs teach in batches like V1 and X1.
