IIM

I don't think you will receive GDPI call from IIMs with 82 percentile in CAT. You will have to do really well and score atleast 99.5 percentile to get GDPI calls from atleast few older IIMs. Please understand that on an average 2 lakh students appear for CAT and 82 percentile means there are 36,000 students who have scored more marks than you. Seats in all IIMs combined is not more than 2000.

IIMs are institutes of higher learning in the field of management. IIMs offer PGDM equivalent to MBA. No IIM offers BBA degree.

Yes you can think about it. Initially try to develop habit of reading English newspaper. Mug up word and then take guidance from coaching or friends.

As soon as you complete your second year you can start your preparation for CAT and focus on your English and mathematics.

You have to just focus on CAT and other related exams.

That is not true. However if you graduation percentage in engineering is 78 or 75, you are seriously disadvantaged and would need to do really well in CAT to compensate for that.

Fees of IIM is same irrespective of which major you choose. Also first year course curriculum is same for all and it is only in second year that you can choose HRM subjects. Having said that the fee of different IIMs are different. Fee of IIMA is around Rs.18 Lakhs for two years for IIMB it is close to Rs.20 Lakhs.

Eligibility criteria for CAT is graduation degree. You are eligible for IIM even with a drop year provided you have graduation degree from recognised universty.

You have to first score 50% or above in your degree. And if you want to go into IIMs, have to score above 95percentile in CAT.
