There are three application rounds for most MBA programs, each of which has its deadlines. The deadline for the first round is in September/October. The second round is in December/January, and the third round’s deadline is in April/May. While it is possible to apply in any of the three rounds, we recommend submitting your application in round one or two. The probability of getting accepted decreases significantly as the rounds increase.
Business schools want to admit a group of students that is as balanced or diverse as possible, so there is a chance that applicants with similar professional and academic backgrounds may be chosen over you if you want until later rounds to submit your application. Make sure to check on your school’s website for their deadlines.
