IIM

You may refer to following link to have an idea about IIMC PGP GDPI cut off for batch 2017-19: https://www.iimcal.ac.in/programs/pgp/admission/admission-policy/admission-procedure-for-domestic-candidates.

Nothing is difficult if you really want it. CAT is a little bit difficult but not that much and level of CAT in every section is very high (especially in English). So, you have to do advanced preparation for the same.

You can target other IIMs except ABC. But if you are a general engineer then it will be difficult.

For getting a call you must get 99 percentile.

Hello Sindhan,
As far as my opinion is concerned, unlike IIT's, IIM's are autonomous institutions which means they have to take care of their expenses and they will not get much funding from the government.
They have to give salaries to the very well qualified faculty team. They need to maintain the infrastructure. And they also need to conduct CAT every year.
So, they get all this money from students who join the institution.

Hello Manav,
That depends upon the cutoff and how much percentile you manage to score in CAT.
Go through Shiksha's IIM Call Predictor.

You will get to know how much you need to score to crack any IIM call.
Good luck!

Hello Prasanna,
Undoubtedly IIM would be the best choice, and for that you will have to prepare hard.
If you are in your final year, you can choose to go for CAT 2018.
CAT has three sections:
1.Reading Comprehension and Verbal Ability.
2.Logical Reasoning and Data Interpretation.
3.Quantitative Aptitude
You can find the complete syllabus online.
Go through it.
Go through previous year question papers.
You can join coaching classes if you want to.
Good luck!
