BBA in Aviation is good but if you will do it as a regular course. The distance learning or correspondence has very less value and also starting package and salary in aviation is very less. But, if you pursue as a regular course then you can get good placement assistance with good package also.

For high school teaching, you need to have post graduation. It also depends on what a particular school is looking for I.e the educational requirement.

No, for distance MBA there isn't entrance exam in most of the institute. If you want to do MBA from IGNOU, then you have OPENMAT. If you want to do it from Andhra Pradesh and Telangana and EAMCET and TANCET is there, but there isn't any entrance exam for Madras, Pondicherry, Kurukshetra and Bharati Vidyapeeth.
