In this long-form guide, we will dissect everything you need to know about COMSAE Form 108: what it tests, how it compares to other forms (106, 107, 109, 110), its predictive value, common pitfalls, and a strategic study plan to conquer it. COMSAE (Comprehensive Osteopathic Medical Self-Assessment Examination) is a series of practice exams offered by the NBOME. Unlike third-party resources (TrueLearn, UWorld, Bootcamp), COMSAE is the official assessment. The questions are written by the same people who write the real COMLEX.
Student A scored 465 on COMSAE 108 (failing threshold at her school). She delayed COMLEX by 3 weeks, hammered OMM and biostats, and scored 510 on the real exam. Part 5: Common Pitfalls & "Trick Questions" on Form 108 Form 108 is notorious for specific "weed-out" questions. Watch out for these traps:
Frequently Asked Questions (FAQ) Q: Is COMSAE 108 harder than COMLEX? A: Subjectively, yes. Many students find it harder because it has no experimental questions. Objectively, the topics are identical.
A: There is no official "pass" for a practice exam, but most COMLEX-gated schools require >450 to sit for Level 1.
A: Once. NBOME does not allow retakes of the same form. If you need another assessment, buy Form 109.
If you are a student at a College of Osteopathic Medicine (COM), you have likely heard the whispered warnings and anxious chatter in group chats: “Have you taken Form 108 yet?” or “How predictive is COMSAE 108, really?”
