When we were all done nursing school (20 years ago) our very cool hippie instructor told us to schedule our test asap, the night before go out and have a beverage (if we drank) and do not study for one minute after graduation. It was the best advice ever. Our uptight valedictorian had to take the test 4 times as she just kept cramming all sorts of information into her head and our group all passed the first time around..
