Hi candidate! In PGCET exam, on scoring marks around 40 one can expect a rank around 1000 or above. So a score of 42 can you fetch you a rank around 1200 according to previous data. This rank can get you to take admission in some decent colleges. This is the link for previous year cutoff for mba http://kea.kar.nic.in/pgcet_2018/r1_cutoff_mba.pdf . Hope this will help.All the best!

Thank You!
