This year's AMCAS application opens on May 4 at 9:30 AM EST, and candidates will be able to submit their AMCAS applications beginning on May 28 at 9:30 AM EST.
Because of rolling admissions, submitting a complete application early in the cycle has distinct advantages at many schools. That doesn't mean you should submit suboptimal written materials on the twenty-eighth; instead, you should start early enough that you're presenting your best work.Rolling admissions means that a school takes applications in the order in which they are received and makes decisions about interviews and then acceptances, accordingly. So, as time goes by, there are fewer interview and admissions offers remaining to be made. Think of an auditorium whose doors open to allow guests in. Those in the front of the line get the seats, and those who come later may not have a chair to sit in.
If your application is not complete, your candidacy may not be evaluated early when there are more opportunities for interviews and admissions. So, if you have not already, get started immediately. It could make a huge difference in your available opportunities.
