With September nearly upon us, we’ve compiled a list of Round 1 deadlines at the top U.S. and international business schools. Most MBA programs have three rounds: Round 1 in the fall, Round 2 in winter, and Round 3 in spring.

Though it’s generally not recommended to apply during Round 3, there are exceptions to this rule. Some students believe that Round 1 gives them the best chance of admission, but this is not always the case. Many admissions representatives claim that the difference is negligible. However, if you want to get a jump on your applications, make sure you finish up before the fall deadlines.

But for those who want to submit their application as early as possible, below are the Round 1 admissions deadlines for the top MBA programs.
