IIM Ahmedabad - Indian Institute of Management

If MBA in aviation is offered by MBA schools, I am not aware of that. But just comparing the above two, MBA in HR has better prospects since in aviation you are constraining yourself to one industry rather than a specific function.

Yes, you can. Please appear for PGPM entrance exams like CAT/XAT/IIFT/NMAT. By qualifying those and subsequent interviews, you can get admission to IIMs/XLRI/IIFT/NMIMS and likes to pursue your PGPM.

Since MBA is a masters degree, a bachelors degree is a prerequisite for studying at IIMs. Other than that you need to clear the bare minimum cutoffs of colleges which vary from institute to institute. Scores for IIMs vary from year to year. But a score above 97 percentile will get you calls from atleast new IIM's. The higher the percentile the better.
All the best!

Yes, of course. It is not necessary to have work experience to get admission into MBA colleges. There are many aspirants who apply for MBA colleges without work experience. Weightage of work experience is low at most IIMs.Good luck!

Yes, of-course. All you need to do is prepare well for CAT and at the same time do not screw your academics. IIM-A shortlists people with exceptional CAT score and stellar academics throughout. Just keep that in mind and you can make it to IIM-A too!
All the best!

No, there are no cut-offs as such, but they do take into consideration 10th/12th marks while shortlisting people based on their CVs.
