Admission into an MBA program is much more demanding than seeking admission into an undergraduate program. Many good colleges and universities will require that you present a record of good performance and consistency in your grades. This will be able to convince the panel that you are ready for the work load that shall come with the program. It is a situation that is rather tricky and unless you are able to prove beyond any reasonable doubt that you certainly deserve to be considered for the few places that might be available, you are likely to end up settling for less than what you truly deserve.
