  1. Complete Basic Sciences - Finish first two years of medical school curriculum covering anatomy, pathology, and pharmacology.
  2. Pass USMLE Step 1 - Take the NBME Step 1 exam (Pass/Fail) typically after the second year.
  3. Clinical Rotations - Complete core rotations (Internal Medicine, Surgery, etc.) and pass NBME shelf exams.
  4. Take USMLE Step 2 CK - Assess clinical knowledge and skills application, usually early in the fourth year.
  5. Graduate Medical School - Earn your MD or DO degree.
  6. Begin Residency - Start your residency training program.
  7. Pass USMLE Step 3 - Complete the final NBME exam for independent medical licensure, usually during intern year.

PLAB and NBME: How These Medical Licensing Exams Compare

The PLAB (Professional and Linguistic Assessments Board) exam is the UK equivalent of the USMLE, and many international medical graduates prepare for both PLAB and NBME-style assessments simultaneously. NBME shelf exams and self-assessments use a similar multiple-choice clinical vignette format that builds the same diagnostic reasoning skills tested on PLAB Part 1. Practicing with NBME question banks strengthens the clinical knowledge base needed for both US and UK licensing pathways.

NBME Subject Exam Score Prediction with SSPO

The SSPO (Subject Score Performance Overview) is a diagnostic tool provided by the NBME that breaks down your shelf exam performance by discipline and content area. Reviewing your SSPO report after each NBME subject exam helps identify specific weak areas in pathophysiology, pharmacology, or clinical management that need targeted review. Students who systematically track their SSPO results across multiple shelf exams can measure improvement over time and adjust their study plans before Step 2 CK.

Sample NBME Practice Questions

Try these questions from our free NBME practice tests. The correct answer and an explanation follow each question.

  1. A 16-year-old boy is undergoing evaluation for jaundice. Laboratory studies show normal hepatic enzyme activities, a negative direct antiglobulin (Coombs) test, increased mean corpuscular hemoglobin concentration, and increased osmotic fragility of erythrocytes. Which of the following types of erythrocyte is most likely to be seen on a peripheral blood smear?

    • A. Ovalocyte
    • B. Schistocyte
    • C. Spherocyte
    • D. Target cell
    • E. Teardrop cell

Answer: C. Spherocyte

The combination of jaundice, normal hepatic enzymes, negative Coombs test, increased mean corpuscular hemoglobin concentration (MCHC), and increased osmotic fragility is highly characteristic of hereditary spherocytosis. This genetic disorder causes red blood cells to be spherical, rigid, and more fragile, leading to their premature destruction in the spleen. Spherocytes are the hallmark finding on a peripheral blood smear in this condition.

  • A laboratory test reveals that an organism's cell wall lacks peptidoglycan and instead contains mycolic acids. This organism would be expected to stain positive with which technique?

    • A. Acid-fast stain
    • B. Gram stain
    • C. India ink
    • D. Silver stain
  • Answer: A. Acid-fast stain

    Mycobacteria contain mycolic acids that bind carbol-fuchsin and resist decolorization with acid-alcohol, making them acid-fast positive.

  • A 22-year-old college student develops fever, pharyngitis, and posterior cervical lymphadenopathy. A peripheral blood smear shows atypical lymphocytes. The heterophile antibody test is positive. Which cell type is the primary reservoir for the causative virus?

    • A. B lymphocytes
    • B. T lymphocytes
    • C. Monocytes
    • D. Epithelial cells
  • Answer: A. B lymphocytes

    Epstein-Barr virus (EBV) infects B lymphocytes via CD21 (complement receptor 2); the atypical lymphocytes seen on smear are reactive cytotoxic T cells responding to infected B cells.

  • A 25-year-old woman presents with fatigue and jaundice. CBC shows Hgb 8.5, reticulocyte count 9%, and spherocytes on peripheral smear. Direct Coombs test is positive. What is the most likely diagnosis?

    • A. Hereditary spherocytosis
    • B. Autoimmune hemolytic anemia
    • C. G6PD deficiency
    • D. Microangiopathic hemolytic anemia
  • Answer: B. Autoimmune hemolytic anemia

    A positive direct Coombs test confirms autoantibodies coating the red cells, consistent with autoimmune hemolytic anemia.

    📋

    📋 What is the NBME and what exams does it make?

    The NBME (National Board of Medical Examiners) is a nonprofit founded in 1915 that develops standardized medical assessments. It co-sponsors the USMLE Step exams and creates the clinical subject (shelf) exams used at the end of core clerkships in U.S. medical schools.

    START NBME PRACTICE TEST
    📝

    📝 What is an NBME shelf exam?

    An NBME shelf exam is a standardized subject test taken at the end of a core clerkship such as medicine, surgery, pediatrics, or psychiatry. Each is a timed multiple-choice exam of roughly 110 clinical vignette questions, and your score is reported on a scaled percentile basis.

    START MEDICINE PRACTICE TEST
    🎯

    🎯 How accurate are NBME self-assessments at predicting Step scores?

    NBME Self-Assessments are the most reliable predictors of actual USMLE performance. Most students score within 10 to 15 points of their most recent self-assessment on the real exam. Taking several assessments over weeks gives a more accurate prediction than a single practice test.

    START NBME PRACTICE TEST
    💰

    💰 How much do NBME practice exams cost?

    Each official NBME Self-Assessment typically costs about $60 through the NBME website. Students usually take several during a dedicated study block, so total spending often ranges from $120 to $300. Some medical schools provide vouchers or reimburse students for these practice tests.

    START PATHOLOGY PRACTICE TEST
    🧠

    🧠 Which subjects do NBME exams cover?

    NBME subject exams span the full medical curriculum: anatomy, biochemistry, physiology, pharmacology, microbiology, pathology, behavioral science, and the clinical disciplines of medicine, surgery, pediatrics, psychiatry, and obstetrics and gynecology. Practicing by subject helps you target your weakest areas before test day.

    START PHARMACOLOGY PRACTICE TEST
    ⏱️

    ⏱️ How long is an NBME shelf exam?

    Most NBME clinical subject exams give you about 2 hours and 45 minutes to answer roughly 110 questions. That works out to under 90 seconds per question, so timed practice is essential for building the reading speed you need to finish every clinical vignette.

    START SURGERY PRACTICE TEST
    📊

    📊 How are NBME exam scores reported?

    NBME Self-Assessments report a three-digit score similar to the USMLE scale, while shelf exams are reported as a scaled score and a percentile comparing you to a national cohort. Your medical school sets the threshold that counts as honors, high pass, or pass.

    START PHYSIOLOGY PRACTICE TEST
    📅

    📅 When should I take NBME practice exams?

    Take your first self-assessment at the start of a dedicated study period to set a baseline, then one every one to two weeks. Schedule your final practice test about a week before the real exam so you have time to fix weak areas without last-minute anxiety.

    START PSYCHIATRY PRACTICE TEST
    🩺

    🩺 How is the NBME different from the USMLE?

    The NBME is the organization that writes the questions, while the USMLE (United States Medical Licensing Examination) is the three-Step licensing exam. The NBME co-sponsors the USMLE with the Federation of State Medical Boards and also produces the separate subject and self-assessment exams.

    START NBME PRACTICE TEST
    📈

    📈 How can I improve my NBME shelf exam score?

    Do large volumes of timed practice questions, review every explanation including the wrong answers, and focus on high-yield clinical reasoning rather than memorizing facts. Repeating NBME-style vignettes builds pattern recognition, and spacing review across weeks improves retention far more than cramming.
