The first available day to submit the 2019 American Medical College Service (AMCAS) applications is May 31st! I hope to submit mine as soon as it opens because of the rolling admissions policy that most medical schools adhere to. Rolling submission means that schools start accepting applicants as soon as they start receiving applications. So, the sooner the submission, the better the chance of acceptance is.
After AMCAS is submitted, I can wait to receive invites to complete secondary applications, then interviews, and finally acceptance!
