i have less than 50% in graduation can i do mba from iim?

• As per the official information the minimum requirement to study MBA you should have at-least AVG 60% of marks ,( atleast 55 % in open category 50% in reserved category )
• Sorry to inform you that you are not qualified for MBA courses , even your CAT score is really high there is no chance of admission with less than 50% marks in graduation  you can repeat the graduation course or improve your score if option available and try for MBA so that you can get into some reputed colleges so that you get job easily.
• Still if you want to continue to join some colleges that takes students for MBA even with less marks please go through the website of the colleges to confirm their credibility and value of certificate they provide

while checking I found this site

Kindly go through the site of these colleges to ensure the credibility and decide , if to join or not

Hope this information helped you

best wishes for your future

Mostly older IIM's focus on the academic record of students including CAT Score , all have different criteria for consideration. But if you are thinking of older IIM's like A/B/C then 50% marks in graduation is not sufficient even if you have a 100 percentile in CAT . However there are other good colleges also for doing MBA like Symboisis , IIFT , IMT , SPJIMR and many other , you can think of them.
