Hi, You should start your CAT preparation atleast 6 months before if you are good at your studies or else 1 year if you are an average student.

Chances are very good. Most probably, you will get a call.

Yes, you are eligible to take admission in JIMS, Rohini.

No, the score is too low, apply for ATMA and MAT of April and May attempt fetch scores above 95% because both of these exams are easy and you can get admission on the basis of that.

You might not be able to get into the top Iims like Ahmedabad, Bangalore, where the minimum requirement is 99 percentile in the CAT exam. You have a fair chance to receive calls from other Iims like:
IIM-Calcutta
IIM-Lucknow
IIM-Kozhikode
IIM-Indore
IIM-Tiruchirappalli
IIM-Raipur
IIM-Udaipur
IIM-Rohtak
IIM-

It's a pretty hard task with 54 percentile and with a non agricultural background but as MANAGE selection is leaned on GD/PI to an equal weightage, you still stand a chance if you can perform exceptionally good in GD/PI.
