I just received my exam results and I felt like I should share my experience. I have visited the forums throughout my study experience and felt like I should contribute as well.
UWorld - 72% (Random, timed, first-pass, 95% finished only)
NBME 5 - 230 (45 days before)
NBME 6 - 220 (16 days before...freaked out a bit
Simulated exam at prometric center - 81% (8 days before)
UWSA - 256 (3 days before)
REAL DEAL = 242
I used only UWorld and reviewing every single detail.
