hey,

most of the students enrolled in bschool dont have many years of work experience or sometimes they join right after completing graduation. if your academic score is not that good you can not get calls from iims as they shortlist candidates according to academic score and cat percentile. getting 99 percentile in cat does not assure you to get call from iim ahmedabad or kolkata. however you may get call from faculty of management studies delhi, pumba etc. see if you work hard , do some internship beside studies, you will definitely get good package, just dont loose confidence .
