Step 1: Foundations of Medicine
The first step of the USMLE focuses on assessing a candidate's understanding and ability to apply basic science concepts to the practice of medicine. Divided into seven major content areas, including anatomy, physiology, pharmacology, and pathology, Step 1 challenges candidates to integrate their knowledge across disciplines. The exam consists of multiple-choice questions and computer-based case simulations, testing not only factual recall but also clinical problem-solving skills.
Step 2: Clinical Knowledge (CK)
- Clinical Knowledge (CK): This step evaluates a candidate's clinical knowledge and ability to apply medical concepts to patient care. The content areas include internal medicine, surgery, paediatrics, psychiatry, and obstetrics/gynaecology. The CK exam format includes multiple-choice questions and computer-based case simulations.
Step 3: Patient Management and Ambulatory Medicine
The final step of the USMLE, Step 3, focuses on assessing a candidate's ability to apply medical knowledge and understanding of biomedical and clinical science to patient care. It includes multiple-choice questions and computer-based case simulations that cover a wide range of topics, including internal medicine, surgery, paediatrics, psychiatry, and preventive medicine. Step 3 aims to evaluate a candidate's ability to manage patients in various clinical settings, including ambulatory care.

USMLE Exam Pattern
The USMLE exam has 3 steps. Earlier the USMLE Step 2 had 2 parts: Step 2 CK and Step 2 CS. But in 2020, the Step 2 CS (Clinical Skills) was discontinued. All three steps of the USMLE are computer-based exams.
The USMLE Step 1 is an 8-hour exam that assesses the basic science concepts and application to medical practice. It contains 280 MCQs divided into 7 sixty-minute blocks each with 40 MCQs.
90 seconds are allotted for each question.
The USMLE Step 2 CK is a 9-hour exam that assesses the clinical science concepts and their application. There will be about 316 MCQs divided into 8 sixty-minute blocks.
90 seconds will be for each question.
The USMLE Step 3 is held over a period of two days. This step assesses the biomedical and clinical science concepts and their applications, patient management, ambulance care etc.
The first day is 8 hours long with about 233 MCQs divided into 6 sixty-minute blocks.
The second day is 9 hours long with about 180 MCQs divided into 6 forty five minute blocks. There are also 13 computer-based case simulations (CCS).
10-20 minutes are allotted for each simulation.
USMLE Exam Attempts
USMLE candidates are limited to a maximum of four attempts per Step, including attempts for Step 2 CS. These three attempts must occur within a 12-month period. The fourth attempt is permissible but should take place at least 12 months after the initial try for that specific examination and must also be at least six months after the last attempt.
Conclusion
Clearing the USMLE is a significant milestone in the medical career of a doctor. Succeeding the USMLE indicates the eligibility to practise as a doctor. Understanding the exam syllabus, content distribution, and adopting effective study strategies can significantly contribute to a candidate's success across all three steps. The preparation journey of USMLE alone gives you the opportunity to experience great learning and challenge oneself.
