Yes, definitely you have fair chances of securing a place among IIMs, having a somewhat good academic record as well as a strong current scorecard at VIT. Just focus on CAT Preparation and target none less than 99 Percentile, being from General Category or perhaps even higher incase youre targeting the Top 6 IIMs. You must even apply for other Management Examinations like XAT, NMAT, SNAP, which too are gateways to some of the Good Management Institutes.
