As Dee Leopold mentioned on the HBS blog, there is no advantage to applying before the Round One deadline. According to Leopold:
“Please keep in mind that… we only begin to review applications after the October 15 Round One deadline. The Admissions Board has no knowledge of whether you submitted your application today or in October. To put it another way, we consider applications in three distinct decision rounds; within rounds, it is not a ‘rolling’ admissions process.”
In other words, don’t needlessly scramble to get your application in early. By all means, resist the urge to prcrastinate and submit your application right at 5:00 PM on October 15, but there’s no reason to submit your application before it’s anything less than 100% perfect.
