Medical scientists usually need a doctorate degree in biological science. Some medical scientists have medical degrees. Medical scientists typically complete courses in biology, chemistry, physics, engineering, mathematics, and computer science.
Status: Medical Student (Accepted) AMCAS states that it usually takes ~4-6 weeks for verification to go through, but looking at the verification trend right now here: http://forums.studentdoctor.net/threads/2014-2015-verification-thread.1076112/ I would say you're looking at 3-4 weeks from the time of submission.
The following 2017 AMCAS application deadline dates were provided to AAMC as of April 2016. Applicants should check directly with medical schools or within the AMCAS application to verify, as these deadlines are subject to change. For combined degree programs (eg., MD/PhD, MD/MBA) deadline information, please refer to the website or the Medical Schools section inside the AMCAS application.
