As I mentioned above: We get the applications in big downloads (hundreds at a time) and they are not necessarily in the order they were sent to AMCAS. Secondaries come back at different times. We distribute them among the reviewers and some will get them back soon, others take their time. Institutional actions need reviewing, something is missing, etc so that mixes the order they get reviewed. An application submitted in July will be reviewed before the one in September, but they one submitted July 1st and Aug 1st, not so much.
