Darden Application Deadlines

Note that Darden traditionally offers an Early Action (non-binding) round for applicants who are especially interested in the school. Darden has not yet released Early Action info for 2008-2009.
Also, the school has not yet released its 2008-2009 application essays, but see last year's Darden essays if you want to get a feel for what to expect in this year's application.
