Okay Anand on a serious note. Your GPA is not the only criterion for shortlisting candidates. In fact I think its the least considered because diff schools have diff syllabi and diff resources and the benchmarks are not the same. For academics there is more weightage given to GMAT something you have cracked big time.
Besides take the time out and go thru the profiles of candidates admitted to the ISB 2008 or 2007 batch and check out their profiles. Few are as prolific as yours. FOr a candidate with above 5 years of work ex obviously more attention would be paid to the workex and not academics which is a guage of the candidate as a kid.
So dont worry I'd say. Make a good application. YOu will definitely be called for the interview and once you get there its all in your hands then. Just be yourself, be confident, be prepared and I think that should be it. YOu will be in your dream school.
Cheers,
Jose.
