Hello, Case 4th year here. If I remember correctly, a typical day during preclinical years is as follows: MWF: IQ from 8-10, then lecture from 10-12. Free time after that. Tuesday morning from 8-10 there is a small-group seminar about social aspects of medicine / "Touchy Feely Tuesdays," followed by anatomy lab from 10-12. Thursday is review day and is entirely optional. Review lectures are recorded online and you can watch them later at your leisure or show up in person if you have questions.
Preclinical years are also a true P/F, i.e. there is no internal ranking system. If you pass, you're on equal footing with your classmates. AOA is determined by clinical grades (Honors, commendable, pass, fail). From what I understand, the top 25% of the class is invited to submit an anonymous CV to the AOA committee, who then elects the new AOA members, taking into account research, leadership, service, etc. in addition to clinical grades.
Congrats again on getting in!
