Hi,
If you are aiming for IIM Ahmedabad and IIM Calcutta, then there is no such issue. You must get 99+ percentile, and perform extraordinarily in GD and personal interview, then you see yourself flying into the IIMs. Thank you. If further queries, you can always ask.

You will definitely get an internship opportunity as that is a mandate. Most people can expect to get a job in final placements, it is mostly subject to whether they want that that job or not. In the latter, people prefer applying off campus.

To get admission in IIM-Ahmedabad, you have to first complete your graduation with at least 50% marks. then you have to compete in Combined Admission Test (CAT) and after clearing CAT, you will get a call for the academic written test (AWT) and the final selection.
Good luck.

There are various scholarships that are available post seeking admission into IIM (A). One needs to score a minimum of 98+ percentile in CAT to get an invite for a PI (personal interview). Class 10th & 11th scores are not relevant here. You need at least 50% marks at your graduation level exams.
