The schedule they put us on at the UofC was super helpful and kept me sane in the end. This is my adaptation of their schedule.
December:
Decide on how you are going to study for the April MCAT - if you choose a prep course, register for that course, if you choose self study, buy your books/materials.

Complete Draft of AMCAS Personal Statement
Register for April MCAT
March:
Request LORs
Last days to register for April MCAT

Take the April MCAT
Check to see which LORs have been sent in
Choose study method for August MCAT if applicable
May:
Begin filling out AMCAS / AACOM application
Check again to see which LORs have been sent in - put pressure on any recommenders who have not turned in letters
