As above, i cant stress enough the need to relax and not study the day before the test, as counter intuative as it seems, there is no way that one extra day of studies will affect your score and the relaxation will be needed if you've put the time in.
As far as relaxing now...for the last couple of days, even out your schedule if you havent allready. Wake up the same time you will on test day, study for set hours, get good sleep, you can try ambien if you got it but there are memory effects if you limit your sleep hours which I think most med students tend to do... I wouldnt take it.
The WORST thing you can do is panic, if you are doing well on Q bank or other practice things, do those and let yourself know you're the ****. If you're not doing well STOP taking them now, again, no amount of information taken from 200 more questions will help your test score if your too freaked out to function. Confidence is a HUGE portion of this test and if you think you can't remember anything it will be a self fulfilling prophecy. Good luck.
