It will be difficult for u to get in new IIMs but you can try for some top Institutes like SP Jain SIMSREE Great Lakes KJ Somaiya

Close to 97%. But those who got through with 97% had a great profile and work experience. So the minimum target should be 99% actually, if you ask!
For the second part of the question, you do stand a chance if you score well in CAT. MBA is not just about marks, there are many other things taken into consideration, such as extra-curricular activities, communication skills, aptitude and knowledge.

Different B-Schools have different percentile cutoffs. To get into an IIM, you will need to score at least 99 percentile. Also you will need to clear the individual subject cutoff which typically is around 95 percentile. For others like FMS you will need 98.5 percentile. For new IIMs these could be 95-96 percentile. I would suggest you contact alums/students of the school you are targeting to get an accurate answer.

IIMs usually do not disclose the marks, however they do disclose percentile for each candidates. To get into an IIM, you will need to score at least 99 percentile. Also you will need to clear the individual subject cutoff which typically is around 95 percentile.

No, you have to prepare for Quant, Data Interpretation, Logical Reasoning and Verbal Ability separately. It doesn't associate with B.Com or BBA.

Yes you should prepare in your final year itslef. nevertheless, aftter Bcom it is always good. So keep putting 8hrs of hardwork daily and give minimum of 10mocktests bfore CAT final exam.

There is no caste discrimination at JIIT, Noida. You could get sector 128, JIIT Noida on the basis of your 92 marks only!

CAT PGDM cutoff last year was around 70 percentile.

Another angle to the point is that the Tag of a top B-school will boost your starting grade at a great cooperate which otherwise you'll need to work up the ladder.
