Frequently Asked Questions
What is the USMLE and why do I need it?
The United States Medical Licensing Examination (USMLE) is a three-step exam series required for medical licensure in the US. It tests your ability to apply medical knowledge and skills in real-world patient care. All MDs (and most DOs) must pass it to practice medicine here.
What are the three Steps of the USMLE?
Step 1: Tests foundational scientific concepts, with a focus on principles and mechanisms of health, disease, and therapy. It is a multiple-choice exam.
Step 2: Divided into two parts:
- Clinical Knowledge (CK): Assesses medical knowledge and understanding of clinical science essential for patient care under supervision.
- Clinical Skills (CS): (Note: Step 2 CS was permanently discontinued in 2021.) Its competencies are now integrated into other assessments.
Step 3: Focuses on patient management and assesses whether you can apply medical knowledge and understanding of biomedical and clinical science essential for the unsupervised practice of medicine.
Who is eligible to take the USMLE?
Eligibility is primarily for:
- Medical students and graduates from LCME-accredited programs in the U.S. and Canada (MD degree).
- Medical students and graduates from AOA-accredited programs in the U.S. (DO degree).
- Medical students and graduates from international medical schools (IMGs) listed in the World Directory of Medical Schools.
How long should I prepare for each Step?
Preparation time varies by individual, but general guidelines are:
- Step 1: 3-6 months of dedicated study time after completing core basic science courses.
- Step 2 CK: 2-4 months of dedicated study, often during or after clinical rotations.
- Step 3: 1-3 months, typically taken during the first or second year of residency.
What are the best resources to prepare for the USMLE?
The most widely used and highly recommended resources include:
- First Aid for the USMLE Step 1 (and Step 2 CK): The quintessential review books.
- UWorld: Considered the gold standard for question banks for all Steps.
- SketchyMedical: For visual learning of microbiology and pharmacology.
- Pathoma: For mastering pathology concepts.
- Prephow: For a comprehensive knowledge library and additional practice questions.
How important is the USMLE for getting into residency?
The USMLE is a critical component of the residency application. Step 2 CK has become the primary numeric score for program directors to screen applicants, especially after Step 1 became pass/fail. High scores, along with letters of recommendation, clinical experience, and personal statements, are vital for a successful match.
Can international medical graduates (IMGs) take the USMLE?
Yes, IMGs must pass all steps to apply for residency via ECFMG certification. Step 1 and Step 2 are often taken abroad, but Step 3 requires a US visa or residencyinya status. Scores need to be competitive for matching.
