MBA in USA

You don't need to appear for GRE unless you are planning for MS in the US. What matters the most is GMAT. However, as far I know there is no exemption as such in US universities for GMAT which Means you must need to score good marks in GMAT (it actually differs for every university). Additionally, you also need to have a good band score in IELTS or TOEFL (if the medium of instruction in your last attended university is not English).
Hope this helps.
Good luck.

Hi,
For MBA in aviation management, you surely need to have work experience. The can have industrial or academic experience. For e.g., if you have worked as a flight engineer or project manager, research assistant, analyst, etc. These experience will sound towards your profile. You just need to present your experience in a relevant manner. Hope this helps.

Hi,You may approach these universities, University of California at Los Angeles (Anderson). Columbia University. University of Chicago (Booth).

Yes, you can but firstly, you have to give IELTS Exam. On the basis of your IELTS score, admission will be decided, minimum 6.5 band is required.

Hi Mayank,
If you see (or search on the website of top US Colleges), you will find that there are very few colleges in the USA or UK, who provide integrated courses. Second thing is, there is no such thing as B.Com rather you will do B.A. (Economics) or Bachelors in administration or B.Sc. In Finance etc. However, I'd recommend you to go for B.Com or BBA first in India and then apply for MBA abroad.

Hi, since you don't have work experience, I doubt you will find options. 2 years minimum experience is required for MBA abroad applicants. You must also have a good GMAT score.

Marymount California University, Trine University, Lewis University, Westcliff University.

I think so. Since top b-schools in USA such as Harvard Business School, Stanford Graduate School of Business and others may have a higher cutoff percentage; just look at the criteria and all others terms and conditions related to it. Top B-Schools in USA are Harvard Business School, Stanford Graduate School Of Business, Columbus Business School etc. are top b-schools in USA.
