Rejections Timeline

Harvard: March (along with the other non-rolling schools)
Hopkins: a couple waves throughout the year
Stanford: a couple waves throughout the year

You can be rejected from some schools as early as August and as late as the next August (if you're on a waitlist).

 

Final rejection letters for a current class that started orientation last week went out first week of this August. You can also get a last minute waitlist into a school up until orientation begins; even up until actual classes start.
