Regarding cutoffs in IITB
The admission session has not yet started for IITB , but going through previous year's cutoff announcement on their webpage , we can make some idea. Here is the link : http://www1.iitb.ac.in/newacadhome/Cutofffiles/DeptMtechCutoff ... call then that would be a waste. So can someone please clarify , when they publish their cutoff score? Thanks
