MCAT vs. USMLE: The Ultimate Battle for Future Doctors!

Ari Horesh

As an aspiring medical professional, you've likely heard whispers about the MCAT and USMLE exams. But what are they, and how do they differ? Fear not, future doctors: this article will serve as your ultimate guide to understanding these two critical exams, their importance in your medical journey, and how you can prepare to conquer them. Let the battle begin!

What is the MCAT?

The Medical College Admission Test (MCAT) is a standardized, multiple-choice exam required for admission to most medical schools in the United States and Canada. Administered by the Association of American Medical Colleges (AAMC), the MCAT assesses your problem-solving, critical thinking, and knowledge of natural, behavioral, and social science concepts necessary for the study of medicine.

MCAT Structure

The MCAT consists of four sections:

Chemical and Physical Foundations of Biological Systems (59 questions, 95 minutes): This section tests your understanding of basic biochemistry, biology, general chemistry, organic chemistry, and physics principles.

Critical Analysis and Reasoning Skills (53 questions, 90 minutes): Also known as CARS, this section measures your reading comprehension, analytical reasoning, and problem-solving skills in humanities and social sciences passages.

Biological and Biochemical Foundations of Living Systems (59 questions, 95 minutes): This section assesses your knowledge of basic biology, biochemistry, organic chemistry, and cellular and molecular biology concepts.

Psychological, Social, and Biological Foundations of Behavior (59 questions, 95 minutes): This section evaluates your understanding of psychological, sociological, and biological factors influencing behavior and mental processes.

In total, the MCAT takes 7 hours and 30 minutes to complete, including breaks and a tutorial.

What is the USMLE?

The United States Medical Licensing Examination (USMLE) is a three-step examination required for medical licensure in the United States. Administered by the Federation of State Medical Boards (FSMB) and the National Board of Medical Examiners (NBME), the USMLE assesses your ability to apply medical knowledge, skills, and understanding of clinical science essential for the provision of patient care.

USMLE Structure

The USMLE consists of three steps:

Step 1 (280 multiple-choice questions, 8 hours): This exam assesses your understanding of basic medical science, including anatomy, biochemistry, immunology, microbiology, pathology, pharmacology, and physiology. Step 1 is typically taken after your second year of medical school.

Step 2 CK (Clinical Knowledge) (318 multiple-choice questions, 9 hours): This exam evaluates your ability to apply medical knowledge, skills, and clinical science principles necessary for patient care under supervision. Step 2 CK is usually taken during your fourth year of medical school.

Step 2 CS (Clinical Skills): This practical exam tests your ability to communicate with patients, gather medical history, perform physical examinations, and write patient notes. Step 2 CS has been discontinued as of January 2021.

Step 3 (Day 1: 233 multiple-choice questions, 7 hours; Day 2: 180 multiple-choice questions and 13 computer-based case simulations, 9 hours): This exam assesses your ability to apply medical knowledge and understanding of biomedical and clinical science essential for unsupervised practice. Step 3 is taken during residency training.

MCAT vs. USMLE: Key Differences

While both MCAT and USMLE serve as critical milestones in your medical journey, there are some key differences between the two:

Purpose: The MCAT is an entrance exam for medical schools, while the USMLE is a licensing exam for practicing physicians.

Timing: The MCAT is taken before entering medical school, while the USMLE is taken during medical school and residency.

Content: The MCAT covers basic science, critical reasoning, and behavioral science concepts, while the USMLE focuses on clinical knowledge, skills, and patient care.

Format: The MCAT is a single, multiple-choice exam, while the USMLE is a three-step examination with multiple-choice questions and computer-based case simulations.

Preparing for the MCAT and USMLE


Study Materials: Utilize resources such as AAMC's official MCAT practice materials, textbooks, and online resources.

Study Plan: Create a personalized study plan, allocating time for each section and regularly assessing your progress through practice exams.

Develop Critical Reasoning Skills: Practice reading comprehension and problem-solving in humanities and social sciences.

Test Taking Strategies: Learn time management, question-answering techniques, and how to handle test anxiety.

Join a Study Group: Collaborate with fellow pre-med students to share knowledge, resources, and motivation.


Study Materials: Use resources such as USMLE Step 1 and Step 2 CK review books, question banks, and online resources.

Clinical Rotations: Apply your medical knowledge and skills in real-world clinical settings during medical school.

Study Plan: Develop a study plan that aligns with your medical school curriculum and clinical rotations, with regular assessments through practice exams.

Test Taking Strategies: Master time management, question-answering techniques, and stress management for exam day.

Mentorship: Seek guidance and advice from senior medical students, residents, and attending physicians.

In Conclusion

The battle between MCAT and USMLE is not a competition, but rather a series of milestones that future doctors must conquer on their journey to becoming licensed medical professionals. By understanding the differences between these exams and diligently preparing, you'll be well-equipped to tackle these challenges and emerge victorious in your medical career. Now, go forth and conquer, future doctors!
