IIM

Hello Akash,
To get a call from IIMs, your board exam marks or Bachelor's degree score is not important. But you need to have at least 50-60% in the Bachelor's degree.
You need to have a good percentile in CAT (Common Admission Test) exam. For top IIMs, your percentile should be atleast 90 and above.
Your profile also plays a major role.

You can't get into IIMs after 12th.

All most all students from legacy IIMs ( Ahmadabad, Bangalore, Calcutta, Lucknow and Indore) are able to get job in campus placement with reasonably high salary.

Only IIM, Indore has 5-years integrated programme in Management (IPM). You may appear in the entrance examination for IPM conducted by IIM Indore.

Hello Tanya,
The difficulty level of a What, GD and PI of any B-school depends directly upon the preparation for the same. So if you have prepared and practised well, then you should not face much difficulties in clearing these interview rounds. Good luck!

Hello Siddhant,
Pumba is a better option than IIM Bodh Gaya as it is more established, better ranked and offers good placements than the IIM. Also the ROI is not an issue for Pumba.

You are advised to appear for CAT to seek admission in PGP in IIMs.

In Pune, there are many colleges, who offer a good salary package.
And, Symbiosis which is international recognised and good placement in a good company.
