Which are colleges offering part time/Evening class MBA program?

Answer 1

There are hundreds of these. In which country are you looking? If in the U.S., Business Week (www.businessweek.com) does separate rankings of full-time and part-time MBA programs. There are more part-time than full-time programs, because almost all schools which have a full-time program also have a part-time program, but the reverse is not true (just because a school has a part-time program doesn't mean that it will have a full-time program).
