Hi

This is a bit difficult to predict the rank required in to get a seat as cut off  keeps changing every year  depending upon various factors like  number of students that appeared in the jee advanced exam, kind of marks obtained by them , toughness level of the examination , number of seats available for the branch you want etc.

When we go through previous year trend then ,

In round 6 of josaa counselling  , 5227 obc  rank in jee advanced for obc category  closing rank for gender neutral in IIT madras  and it was for Biological Sciences (5 Years, Bachelor of Science and Master of Science (Dual Degree))

You can check the same at
