108 | Comsae Form
Form 108 adheres strictly to the weightage guidelines published by the NBOME. While every test is slightly different, students who have taken Form 108 report a consistent distribution across the following domains:
Autonomic pharmacology, antimicrobial mechanisms of action, and classic "buzzword" presentations of infectious diseases.
: Form 108 often features shorter question stems than the actual COMLEX, which can lead to timing discrepancies during the real exam if students don't practice with a manual timer. comsae form 108
Form 108 is directionally predictive, but not absolute. A passing score = you are safe. A borderline score (420-440) = significant risk of failure.
Viscerosomatic reflexes are heavily tested. Memorize the T1–L2 sympathetic levels for all major organs (e.g., T1–T4 for the heart, T5–T9 for the upper GI tract). Form 108 adheres strictly to the weightage guidelines
To maximize the value of Form 108, it should not be taken in isolation. The NBOME advises using your COMSAE result alongside other markers of academic performance, such as your COM curricular program and COMAT examination scores. To that end, the best way to prepare for the COMSAE is by using dedicated COMLEX resources like question banks (e.g., COMQUEST, COMBANK) and other study materials. Effective preparation involves several key strategies:
However, research provides a more nuanced picture. A 2025 study published in the Journal of Osteopathic Medicine found that a student's . This study established a predictive model where the average clinical subject COMAT scores, first-time COMSAE Phase 2, preclerkship examination mean, and COMLEX Level 1 pass/fail status explained a substantial 73.9% of the variance in Level 2-CE performance. Form 108 is directionally predictive, but not absolute
Some students have observed that newer COMSAE forms may be more challenging as the form numbers increase. The NBOME has clarified that COMSAE forms are designed to reflect the current COMLEX-USA content and difficulty level, not to create a progressive difficulty scale.
If you are studying concurrently for the USMLE Step 1 using resources like UWorld, navigating Form 108 requires a minor shift in mindset.
