IIM

For admission to IIM for MBA the UG course is not the criterion. You can do your graduation in any subject. For IIM you will have to give a separate exam (CAT). However, personally speaking I would advise to opt for CSE instead of agriculture engineering.

Besides a great peer group and tested IIM pedagogy, it has a small batch size which makes us more of a close knitted family. Also the campus is situated in the erstwhile summer palace of the Mayurbhanj kings of Orissa. It is situated at a hill station having the most beautiful of seasons and weather.

You can check the eligibility criteria in the IIM Shillong website http://www.iimshillong.ac.in/admissions/pgp-admissions/#w349 . All the details are mentioned in the wesite.

Hi Damini,
It depends on your category if general 99+ would be enough. However, percentile is not the only criteria.IIMs look for overall performance and potential of a candidate apart from academics, there is a significant shift in the selection process from academic-centric to overall performance and capabilities of the students. The Cutoff percentile is different for different IIMs and it changes every year, you can get the report on official websites of respective IIMs.

The chances are good, but it would also depend on your academics and qualifications.

Yes, but you need to have minimum 50% marks in graduation to be eligible for it.

Determination, continuity and hard work in your preparation. Solve the problems in less time, practice as much as possible.

It was around 80 percentile for most IIMs.

To get admission in legacy IIMs is quite tougher in comparison to public sector Banks PO examination as competition is very high for legacy IIMs. But, toughness and competition will be similar for new IIMs and PO examination.
