I'm currently preparing for the USMLE step 1.
I've heard that if you master physiology you can figure out a lot of questions.
That sounds like less studying time so that would be sweet. In an attempt to master physiology I've constructed some formula sheets for the big sections; Cardiac, Respiratory, and Renal.
I've decided to post them here for future reference.
Cardiac:
