USMLE Step 1 Format

Since this is your first Step exam, you need to pay extra close attention to the Step 1 interactive testing experience. This free online tool will show you how to navigate each item and function of the online test. Step 1 consists mainly of multiple-choice questions (MCQs), which are referred to as “items.” 

Step 1 of the USMLE takes one day (eight hours) to complete and is divided into seven 60-minute blocks. There are about 40 questions in each block, though there may be less as the exact number of questions on each block varies. The total number of questions (or “items”) on the exam form will be no greater than 280.

USMLE Step 1 Question Formats

The multiple choice questions on the USMLE Step 1 exam are designed to measure your basic science knowledge, and ask the testee to “interpret graphic and tabular material, to identify gross and microscopic pathologic and normal specimens, and to solve problems through application of basic science principles.”

It should be noted that there is a tutorial at the beginning of the Step 1 exam, but it does not contain as much detailed information as the tutorial in the Step 1 interactive testing experience. You’ll also need to review the audio findings on the simulator to become familiar with how audio test items function before you take your test.

What Is On The USMLE Step 1?

According to the USMLE Content Outline, the MCQs on the USMLE are designed to test your basic science knowledge and comprehension skills. Here is a breakdown of the subjects on the Step 1 exam:

  • Pathology
  • Physiology
  • Pharmacology
  • Biochemistry & Nutrition
  • Microbiology
  • Immunology
  • Gross Anatomy & Embryology
  • Histology & Cell Biology
  • Behavioral Sciences
  • Genetics

How Long Is The USMLE Step 1?

The USMLE takes one day to complete, and is administered in one 8-hour testing session. Each of the seven sections in the exam takes one hour to complete. Examinees will be allowed one approved break time. If you require test accommodations, you may apply through the USMLE website.

When Should I Take the USMLE Step 1?

Most students take the USMLE Step 1 exam at the end of their second year in medical school. This timeline is recommended to allow students enough time in school to learn the necessary material for the Step 1 exam. Technically, you can take the USMLE Step 1 exam anytime after the three-month period post successful registration. 

In order to register, you must be a graduate or current student in an MD program. So, the earliest you can possibly take the USMLE Step 1 exam is after you have enrolled in medical school.

How To Prepare for the USMLE Step 1

Here are some USMLE Step 1 study tips from our experts. If you’re studying for the USMLE and want a personalized study guide, consider setting up a consultation with one of our experts.

1. Start Studying Early

It is recommended to start studying six months or more before you intend to take the USMLE Step 1 exam. Some students even begin a year before the test. Starting early will ensure that you will have time to cover all of the material on the test. 

Don’t forget about the USMLE as you’re navigating medical school! While you’re studying, you should be in the first or second year of your MD degree. Beginning the process of memorizing important information will help you stay sharp throughout the year and better retain information. 

2. Familiarize Yourself With The Software

The USMLE stresses that you should take plenty of time to familiarize yourself with the software you’ll use on your test. By reviewing the Step 1 interactive testing experience early, you’ll have a better idea of what to study for and what to expect. Throughout your six months of study time, you should continuously refer to the online simulator.

3. Take The USMLE At The Right Time

Most students take the USMLE at the end of their second year; however, you have the option to take it at any point after enrolling in medical school. We strongly recommend waiting to take the exam until the end of your second, or even in third year, if you do not feel prepared. 

You’ll learn the materials you’ll need to know for the Step 1 exam in medical school, so the more time you spend learning, the better. Additionally, waiting will give you enough time to start studying for the test several months before your scheduled exam.

4. Create A Comprehensive Study Schedule

Keep yourself on track and organized by creating a study schedule that encompasses your busy med-student life. You can do this on your own or with the assistance of an experienced USMLE tutor. Keeping a schedule will also help to reduce stress throughout your first and second years of med school.

4. Who Is Eligible For USMLE Step 1?

To be eligible for the USMLE Step 1 exam, you must be a current or graduate medical student (MD) of a US or Canadian medical school. The medical school you attend must be accredited by the Liaison Committee on Medical Education (LCME).

5. Can I Retake The USMLE Step 1?

Final Thoughts: USMLE Step 1

Step 1 of the USMLE is commonly considered the most challenging of the three USMLE Step exams. You’ll be using unfamiliar software, and you will have to make time to study throughout your first and second years of medical school. 

To properly prepare yourself, you should thoroughly review the USMLE interactive testing experience multiple times. You should also build a rigorous study schedule and maintain it throughout the six to twelve months before your exam. Do everything you can to reduce stress and get familiar with the test format and the material. 

Good luck!
