Is there anyone who has made it into top institutes like IIMs, FMS, SPJIMR, XLRI, etc. with average or below average scores in school and graduation?

Yes, if you have average percentage scores in 10th, 12th, and graduation, then also you can make your way to premier institutes like IIMs, XLRI, SPJIMR, etc. The academic score is not the only criteria for the selection of students in an MBA.

The points below give a brief overview of the categories that these institutes give stress in the selection process:

1. SP Jain Institute of Management and Research gives a lot of attention to the work experience. A good CAT/ XAT score is necessary for securing an interview call at this institute. Build your profile along with a stronger academics background, in order to convert your call.
2. FMS Delhi gives lot of preference is given to the CAT score itself. A very high weightage is given to the CAT score in the interviews of FMS too, which even increases the cut-off of the institute.

Different institutes have different requirements, as per the recruiters taking the interviews of students. This makes it evident that there are chances of students with low school and graduation percentages, but with a good entrance score and excellent work experience.
