IIM Ahmedabad - Indian Institute of Management Vastrapur Answered Questions

Do understand that each institute have separate selection criteria to shortlist students and finally offer them admission to their MBA courses. Having said that, with decent academic credentials and average WAT-PI with any percentile around 99 you should get admission to top B-Schools. This is again my personal view & cannot be validated with data.

Admission to IIMs is via a common entrance examination called CAT. After clearing the entrance examination, based on your score, past academics and relevant work experience IIMs shortlist students for written ability test & PI where they will gauge your interest for pursuing MBA. After clearing the same, one gets admission to any of the IIMs.

There is no hard and fast rule and usually depends on the overall performance of applicant and selection criteria of IIM A of that admission year. As a rule of thumb, 90%+ in 10th/12th and 85% in graduation (read engineering) would require upwards of 99.6 percentile in CAT. The lower the academics, the more the CAT score to compensate. Academic diversity do allow some slack in CAT percentile.

I think you need to clear the interview stage cut-off for IIM A to get a call and do well in the interview to convert the interview call. It is not a question of how you completed your degree, but how your composite score (as calculated by IIM A; the process is given on the website) compares with others and whether it makes the cut or not. In the interview, it is likely that this question regarding the completion of your degree would come up, but it is a matter of how well you handle the situation that determines your chances.

Since you have completed a 3-year degree in 5 years, I am assuming you have not-that-great academics. If that's the case then getting admission to IIM-A will be difficult even after getting a high percentile as IIM-A gives substantial weightage to academics.
