Is there any way you can reschedule your test? I'm assuming not since you're asking for help here, but thought I'd throw it out there just in case.
What were your weakest areas on the two NBMEs that you took? Pick the worst two or three and really focus on those between now and Monday, especially if they're heavily tested subjects like general path concepts, pharm, micro, physio, or biochem. Let the rest of it go. You don't need to ace every subject to pass the test. Best of

to you.
