MCAT vs USMLE: What’s the Difference?

February 20, 2024

minute read

Pursuing a medical career is very demanding, and the course alone is tedious and long. Aside from the fact that the medical programs are difficult, you also need to take a qualifying exam for you to get into med school

Also, for those med students applying for licensure, you need to take not one but a battery of tests to practice medicine. These tests are taken during your med school and while you are still in your residency. 

The Medical College Admission Test (MCAT) and the United States Medical Licensing Examination (USMLE) are amongst the standardized examinations suited for those who want to continue their studies in medical schools and get a medical license. 

This article will go through the different exam structures, exam fees, and other characteristics of the MCAT and the USMLE. We will give a comprehensive comparison between these two.

What is the MCAT?

It is a standardized exam that is designed for individuals who want to pursue any medical profession, including internal medicine, surgeon, pathologist, pediatrician, cardiologist, and more. 

The MCAT is a computerized exam that consists of four test sections, and you are given roughly 7 hours and 30 minutes to finish it. Moreover, the test questions are specifically made to be challenging and tricky to gauge the test-takers comprehension and analyzing skills thoroughly. 

It is administered by the Association of American Medical Colleges (AAMC), and it is designed to assess your knowledge of the following fields of science, including Physics, BiologyChemistry, Psychology, and Sociology

Furthermore, the MCAT utilizes multiple-choice questions wherein each of its four test sections contains 50+ test questions.

The MCAT Four Test Sections are :  

What is the USMLE?

It is a three-step examination including USMLE Step 1, USMLE Step 2 CK and CS, and Step 3, which are intended for medical students and those who have already finished their medical course. 

The USMLE, or the United States Medical Licensing Examination is a medical licensure exam for medical professionals in the US. 

Also, the goal of the USMLE is to assess the individual’s content knowledge of the different branches of sciences, concepts, and principles, which are the fundamentals of medicine. And on how they can apply these learnings in real-life settings. 

It is jointly administered by the Federation of State Medical Boards (FSMB) and the National Board of Medical Examiners (NBME). The test duration differs depending on which step of the USMLE you will take, approximately every exam takes about 8 to 9 hours. 

The USMLE Three Step Examinations:

  • USMLE Step 1
  • 7 Blocks (Anatomy, Behavioral Science, Biochemistry/Medical Genetics, Microbiology/Immunology, Pathology, Pharmacology, and Physiology)
  • USMLE Step 2 CK
  • 8 Blocks (Internal Medicine, Obstetrics and Gynecology, Pediatrics, Preventive Medicine, Psychiatry, Surgery, and other areas related to providing care under supervision)
  • USMLE Step 2 CS
  • Patient Encounters and Hands-On Examination
  • USMLE Step 3
  • History and Physical
  • Lab and Diagnostic Studies
  • Diagnosis
  • Prognosis
  • Pathophysiology

MCAT vs. USMLE: What are the Similarities?

The MCAT and USMLE are similar in the sense that both of them are used in the medical field. 

These two exams are trusted by various institutions worldwide to deliver a quality assessment of an individual’s knowledge, skills, and abilities needed to be successful in practicing medicine. 

Also, the MCAT and USMLE test an individual's readiness to take a medical course or practice a medical profession.

Regarding their exam contents, they both focus on the different branches of science and principles usually encountered in med school.

Exam Format and Structure: MCAT vs. USMLE

The MCAT and USMLE differ significantly in their exam structure and format. They are similarly taken on computers which is more efficient for their test-takers. 

The USMLE is a three-step examination with different test sections per step. And these USMLE tests are taken on different schedules during your stay at the university and not only in one sitting.

The MCAT has only four test sections that measure the student’s problem-solving skills and critical thinking. And also their understanding of the basic science concepts and principles that are encountered in med school. 

The USMLE is much longer for the exam length depending on the specific exam you will take. Note that every USMLE test differs in its exam duration and in its test section contents. 

For example, in USMLE Step 1, the test duration is approximately 8 hours in total, divided into seven blocks or test sections within 60 minutes given in each block. 

In comparison, the MCAT only takes about 7 hours and 30 minutes in one sitting, which means you will complete the whole exam in one day.

Scoring: MCAT vs. USMLE

These two exams highly differ in terms of their scoring system. The MCAT assigns specific score points for each of its four test sections which range from 118 to 132 points

All four test sections’ scores will be added to get an overall MCAT score that ranges from 472 to 528 points. The MCAT scores can also be interpreted using the percentile ranks, wherein it is an accumulated score from the previous test-takers of the MCAT. 

On the contrary, the USMLE has a different scoring system for each of its three-step exams. For example, USMLE Step 1, is graded with a pass or fail and it is based on a score range between 1 to 300 points wherein the passing score is 196 points. 

While the USMLE Step 2 has a similar scoring range between 1 to 300 points but the passing score is 209 points

In the USMLE Step 2 CS, the scoring is not based on numerical scores instead it is graded only as pass or fail. Also, it is different compared to USMLE Step 1, USMLE Step 2 CK, and USMLE Step 3 scoring systems.

Which is Easier: MCAT vs. USMLE

The USMLE is a much harder and more complicated exam compared to MCAT. Though the MCAT is known to be a difficult admission test, the USMLE is much more challenging. 

The USMLE intends to measure the readiness of its test-takers to practice medicine. Also, the test contents and questions are a much more in-depth approach in comparison to MCAT’s test questions. 

Also, the MCAT objective is to measure the test taker’s knowledge of the fundamentals of science and other scientific principles relevant to the medical profession which is a basic requirement whenever you want to get into med school. 

Thus, the big difference between the MCAT and the USMLE, makes the latter a difficult exam for most.

Should You Take the MCAT vs. USMLE?

You can either take the MCAT or the USMLE depending on your need and intentions. If you are already a medical practitioner based in another country and want to continue practicing your profession in the US, you need to take the USMLE. 

Moreover, the USMLE is a licensure exam for medical professionals. It tests your learning in med school and skills if you are ready to practice your medical profession.  

If you are just planning to enroll in medical school, you should take the MCAT. These two exams serve different purposes, so you should take the one that fits your need.

Additional FAQs – MCAT vs. USMLE

Do I Need the MCAT for the USMLE?

No, the MCAT and USMLE are two different examinations taken by medical students and medical professionals. 

These two exams differ in their purpose, for example, the MCAT is a standardized examination for every medical school in the US and other countries. 

In contrast, the USMLE is a medical licensure exam for those who recently finished med school and for other medical practitioners who want to practice in the US.

Does the MCAT Predict USMLE?

It is still debated if the MCAT is a good predicting factor for the USMLE. Many believe that if you performed well on your MCAT, there is a high chance that you will also get a high score in the USMLE. 

On the contrary, the knowledge and skills that you acquired during your time in med school also is a big contributing factor for you to be successful in taking the USMLE. That is why your MCAT scores are not the only thing that can predict how well you performed in the USMLE.

The MCAT or the USMLE, Which is Better?

These two exams have different purposes, so you can choose which best suits your needs. If you intend to pursue a medical degree, you can take the MCAT since it is used as an admission exam to most med schools in the US and in other countries around the world. 

On the other hand, if you want to get a medical license for you to practice your profession, you may take the USMLE, since it is a licensure exam for medical practitioners.
