IIM Ahmedabad - Indian Institute of Management

For general category student, I don't think you get interview call from any good MBA college. Also because of your low graduation percentage, you will find it difficult to get a call from good college. I would suggest that you prepare well and try again next year. Please keep in mind that you will need to score really good in CAT to get an interview call.

Almost all IIMs have already released their shortlist and I believe interviews for the same would start next week. So, if you haven't received call from any of the IIMs, I don't think you will receive any call from IIMs. Also I don't think 88 percentile would get you calls from other good institutes like FMS etc. You should try again next year and you should prepare well for the same.

To get into IIM-A, you must hold a bachelor's degree with at least 50% marks or equivalent CGPA.
After that you need to give CAT exam. Performance in CAT is an important input in the admission process. You should note that it is important to perform well in each section of the test. In addition to the performance in CAT, IIMA uses academic background for short-listing for AWT & PI.

If you want to take admission in IIMA then you need to do graduation first with more than 55%. After that you need to clear the MBA entrance exam- CAT and score 99 percentile then only you can get admission in IIMA. But it's good to see your dedication. All the best!

Pursuing further management education along with being financial independent is always a desired option. A person pursues MBA keeping in mind ones current work profile and future career aspirations. Since you are into exports, you could also check for institutes that offer MBA in export Management, foreign trade, CRM.
An MBA degree from a good institute will help you in your career. You can check on the institutes that offer part time MBA course and keeping in mind their admission process, apply for the same.

You can, but you will have to perform extraordinarily in the CAT. You will need to score more than 99.8 percentile in CAT to get calls from old IIMs.

Yes, you can definitely get a call from IIM-A if you do really well in CAT. It is important that you score really well in CAT to offset the effect of low marks in graduation.

WIth these percentage it is very difficult to get into IIMs. All the IIMs assign some weight to your pest academic performance. However those aren't strict binding criteria. If you do really well in CAT then you can offset the effects of past academic performance. Also whether or not you have work-experience is not at all a deciding criteria, but if you have some work-experience then it definitely helps a little.
