The MBA program is probably one of the toughest area to get into if you're targeting good schools. AACSB  is probably the minimum accreditation you look at. I hope you've already taken GMAT and you have good GPA. To evaluate schools, go through the US News ranking schools.

Take a look at some BOTTOM part of TOP tier and Tier 3. Try to apply into at least 4- 5 schools out the list. 2-3 top schools (not taking about top 50 or so) and 2-3 Tier 3 schools. Look at their acceptance rate and tuition as well. You should have no problem in Tier 3 schools, but for the top tier, you really have to be competative.

I hope this will help... good luck!
