Dear Ajith, requirements vary slightly. General requirements state that applicants must have completed high school with English as one of the subjects, must take IELTS or TOEFL. For admissions you must have a passport, medical certificate, financial evidence and any other requirement stated by the school. Mount Royal University, Fly Blue bird, Atlantic Flight College are some good ones.

Both are very niche and different with no correlation. Mba in IB has better and wide opportunity in imprt and export and foreign exchange. Aviation management invooves jobs in fleet management, Fuel Management, Cargo Handling, Airport management. Majority of international job are available.

If you do MS from top 10 universities in USA, it will make no difference whether you do MS in CSE or Aeronautical Engineering. Both will gave you similar opportunities.

Top Colleges for Aviation in India which are known for good faculty and high placement records are UEI Global Kerala, University of Petroleum and Energy Studies Dehradun, Patna Women College Patna,PES Institute of Technology Bangalore,Chitkara University Patiala & Hindustan University Chennai.

As a commerce student, after grad u can do mba(finance). U can join aviation industry as a steward boy/air hostress after class 12 only if u hv attractive personality, presentability and good communication skills. After grad, u may also possess mba(aviation management) to get managerial post. Try to get a good college. UPES university is good at aviation management. All the best. Thank you.

Both are different fields. BBA is Management line whereas BSc Nursing is Medical line. Choose as per your interest.
