On rotations, don't stress about your schedule. More effort is put into making the schedule for residents and attendings, students are sort of left by the wayside sometimes.
If no one tells you where or when to report, show up at 6 or earlier and introduce yourself to the team once you find them. I never really bothered paging the resident or fellow because they have so much going on already.
In medical training, life is easier if you just surrender and take your schedule the way it's served. There's not too much you can do to change things so just hang in there and remember it's temporary
