NBME CBSSA study guide

NBME CBSSA · Work through your exam, one topic at a time.

NBME® Self-Assessments are a family of practice assessments published by the National Board of Medical Examiners, described on the NBME site as tools to "evaluate your readiness and practice" for the USMLE®, an NBME Subject Exam, or the International Foundations of Medicine® (IFOM®) Exam. They are not a credential and confer no license; they are readiness checks taken before a high-stakes exam. The NBME CBSSA study guide has 5 sections and about 1,595 words.

01

USMLE Step 1 Preparation

USMLE Step 1 preparation focuses on the integrated basic sciences that explain clinical vignettes: anatomy, physiology, biochemistry, immunology, microbiology, pathology, pharmacology, biostatistics, and behavioral science. The CBSSA is a timed self-assessment that uses Step 1-style items and a performance profile, so practice should emphasize mechanism-to-phenotype reasoning rather than isolated recall.

USMLE Step 2 CK Preparation

USMLE Step 2 CK preparation tests clinical knowledge and decision-making: diagnosis, initial management, preventive care, ethics, quality improvement, and patient safety. Items often ask for the next best step in a stable or deteriorating patient, so the task is to choose the action that changes management or prevents harm.

USMLE Step 3 Preparation

USMLE Step 3 preparation assesses independent practice: day 1 Foundations of Independent Practice (FIP) and day 2 Advanced Clinical Medicine (ACM), including computer-based case simulations (CCS). Content spans diagnosis and management across settings, biostatistics and epidemiology, drug advertisements, abstract interpretation, patient safety, and quality improvement.

NBME Clinical Science Subject Exam Preparation

NBME Clinical Science Subject Exam preparation targets the shelf examinations that follow core clerkships. Each exam samples discipline-specific clinical science-internal medicine, surgery, pediatrics, obstetrics and gynecology, psychiatry, family medicine, or neurology-using vignettes that ask for diagnosis, mechanism, or next step.

IFOM Clinical Science Exam Preparation

IFOM Clinical Science Exam preparation addresses the International Foundations of Medicine Clinical Science Exam, an NBME-developed, computer-based multiple-choice test used by medical schools and international medical graduates to benchmark clinical knowledge. It samples internal medicine, surgery, pediatrics, obstetrics and gynecology, psychiatry, public health, and ethics through clinical vignettes, with emphasis on diagnosis and initial management.
