DO student here, had about 7 weeks of dedicated, used USMLERx, UWorld, Pathoma (did ~2/3 of it...), Sketchy (did all of micro and ~1/3 of pharm), and First Aid for reference. A little Anki towards the last 3 weeks that consisted entirely of my own cards made up of UWorld misses.
Real exam: 256
UWorld first and only pass: 76%
NBME 15 (8 wks out): 230
NBME 16 (4 wks out): 223
NBME 17 (3wks out): 232
UWSA 1 (2.5 wks out): 264
NBME 19 (1.5 wks out): 248
Free 120 (1 wk out): 87%
NBME 18 (4 days out): 252
UWSA 2 (3 days out): 258
NBME 18 and UWSA2 were the most predictive, and I took those within a few days of the real thing, so I guess that makes sense.
I don't have any secrets, or tricks, or great tips. But, as a DO student, don't get psyched out by people saying how hard it is compared to COMLEX or that its way more difficult than what we learn in class, and any other stuff. Just study hard. Best of luck to those waiting.
