COMSAE BSA 107 (often specifically referenced as COMSAE Phase 1 Form 107 or BSA 107) is a self-assessment exam designed by the to help osteopathic medical students prepare for the COMLEX-USA Level 1
. Unlike previous versions, student-purchased forms now include answer keys
delivered with the score report to facilitate focused study. High-Yield Content & Topics
Student reviews and study resources highlight several recurring "must-know" topics for Form 107: Pharmacology & Toxins:
Focus on heavy metal presentations (lead, arsenic, mercury) and substances like benzene. Osteopathic Manipulative Medicine (OMM): Innominate rotations:
Understand that anterior innominate rotation involves tight hamstrings. Techniques:
Distinguish between direct vs. indirect and active vs. passive (e.g., FPR is indirect and passive). Specifics: Review cranial, sacral, and pubic symphysis dysfunctions. Biomedical Sciences: Endocrine:
PTH production in chief cells, its inhibition of phosphate reabsorption in the proximal tubule, and its role in increasing calcium resorption in the DCT. Microbiology:
Differentiation between PSGN (2 weeks post-URI) and Berger’s disease (2 days post-URI). Biostatistics:
Sensitivity equations and study types (cohort vs. cross-sectional). Specialties:
Review pediatric developmental milestones, vaccines, and high-yield OBGYN topics. Exam Structure Total Questions 176 single-best-answer items 4 sections of 44 questions each Time Limit Typically 4 hours comsae bsa 107 answers work

COMSAE (Comprehensive Osteopathic Medical Self-Assessment Examination)
(also known as Phase 1, Form 107) is a common self-assessment tool used by osteopathic medical students to prepare for COMLEX-USA Level 1. Does it come with an answer key? Yes. As of early 2024, the
provides an answer key with the score report for all student-purchased COMSAE forms. This allows you to review which questions you got wrong and verify the correct answers immediately after finishing. Commonly Tested Topics on Form 107 Based on student feedback from platforms like
, the following high-yield topics frequently appear on this specific form: OMM/Osteopathic Principles
Anterior innominate rotations (e.g., tight hamstrings vs. hip flexors). Thoracic Chapman points and Sacral/Cranial OMM basics. Parasympathetic vs. sympathetic innervation. Medical Knowledge Pharmacology
: Teratogenic effects of ACE inhibitors/ARBs (fetal renal agenesis). Infectious Disease
: Cellulitis causes (Strep pyogenes/Staph aureus) and Anthrax/Botulism. : Brain bleeds and multiple sclerosis. : Reproductive tumors and menopause transitions. Stats & Ethics

Renal/Teratogens: ACE inhibitors and ARBs are frequently tested for their teratogenic effect—specifically fetal renal agenesis. Endocrinology: Calcium and PTH regulation is a major focus.
Hypercalcemia/Hyperparathyroidism mnemonic: "Stones, bones, groans, moans, psych overtones".
PTH Action: Inhibits phosphate reabsorption in the proximal tubule and increases calcium resorption in the distal convoluted tubule (DCT).
Thyroid: Hashimoto’s involves antibodies against thyroid peroxidase or antithyroglobulin. Pathology & Microbiology:
Cellulitis: Most commonly caused by Streptococcus pyogenes or Staphylococcus aureus.
Paget's Disease of Bone: High-yield complication is osteosarcoma.
Meckel’s Diverticulum: Remnant of the vitelline duct; can contain ectopic gastric or pancreatic tissue. Toxicology & Pharmacology:
Heavy metal exposures (lead, arsenic, mercury) and bioterrorism agents (anthrax, botulism) are reported as appearing multiple times. Licensure or certification : Comsae Bsa 107 might
Probenecid: Inhibits uric acid reabsorption in the PCT and inhibits penicillin secretion. Osteopathic Principles (OMM)
Innominates: An anterior innominate rotation involves tightness in the hamstring extensors.
Thoracic: High-yield somatic dysfunction patterns often include E SaRa (Extended, Sidebent, and Rotated same side).
Techniques: Be prepared for questions on the descriptions of Balanced Ligamentous Tension (BLT) and differentiating between direct and indirect OMM techniques. Breakdown of Additional Topics Specific High-Yield Topics to Review Heme/Onc

Feedback from examinees suggests that COMSAE 107 can be under-predictive of actual COMLEX performance. Scores on this form have been reported as significantly lower (up to 100 points) than the student's final board score. Effective study resources for bridging this gap include the M3 Anki deck for COMATs and comprehensive review of First Aid for the USMLE Step 1.
However, I'm here to guide you on how to approach studying and understanding the material rather than providing direct answers. The COMLEX series, including Comsae exams, is designed to assess an individual's knowledge, skills, and abilities essential for the practice of osteopathic medicine.
Let’s be brutally honest. Medical school is hard, and board prep is exhausting. The temptation to find a key is real. But here are three reasons this approach fails:
The primary purpose of Comsae Bsa 107 is to evaluate the knowledge, skills, and competencies of medical professionals, likely in a specific area of practice. This assessment may be used for various purposes, such as:
