Yeah, though low, but chances are still there for you to secure BITS Goa Chemical with 247. Last Year, Last Iteration Cutoff for BITS Goa Chemical was 248. Hence you may need to wait till atleast 3rd Iteration. Other Good Options maybe, Civil/Chemical at BITS Hyderabad, Manufacturing at BITS Pilani (253 Lat Year Cutoff) or maybe M.Sc Chemistry at BITS Goa or Hyderabad.
