OMM shelf (COMAT OPP) shelf exam bank
One exam format. Forms are sampled to the published content outline, run as one timed block with the real exam tools (timer, flag, strike-out, lab values), and explanations stay locked until you finish. After each form you get a score report by presentation group and osteopathic domain, with lessons for your weak areas.
Start
Full-length forms and topic practice are part of Elite. Sign in if you already have it.
Fixed mock forms
Three fixed forms per format, built to the same blueprint with no question shared between them. Elite. Status and scores show on the Exams hub.
Practice by topic (tutor mode)
Questions you have not seen in an earlier full form are preferred, so a new form never repeats an old one unless the pool runs out; when it does, the form tells you how many items repeat. Misses go to your Missed Questions deck for daily review.
COMAT Osteopathic Principles and Practice blueprint
Official outline: www.nbome.org/assessments/comat/clinical-subjects · www.nbome.org/assessments/comat/clinical-subject-exams/osteopathic-principles-practice. Weights are paraphrased public ranges. Dimension 1 presentation groups set the area mix; Dimension 2 osteopathic domains are the task axis (matched by keyword rules, approximate).. Re-check the live outline before test day.

About these forms
Independent educational practice. Not an official NBME or NBOME exam, not affiliated with either, and not a score predictor. Questions are original. Bone Wizardry items are not equated to real forms, so the score report shows a percent-correct band and a rough percentile range marked as an estimate. The free sampler uses reviewed-only items.
