Length of the Step 1?
The USMLE Step 1 exam is an 8-hour exam. The exam allocates 7 hours for questions and 1 hour for break time that can be used between question blocks.
The exam consists of 280 questions divided into seven blocks. Each block is allocated 60 minutes to complete. Once the 60 minutes finish, the block is automatically submitted and the student can no longer return to that block of questions. However, if the block is submitted early, any remaining time will be added to your break time.
The 60 minutes of break can be divided in any way between the question blocks. It is completely up to the test-taker to decide how to divide up their break time. However, an important note is that breaks can only be taken between blocks; breaks cannot be taken during a block.
The exam begins with an optional 15-minute tutorial that is deducted from your break time. If you have done the tutorial before, you can skip it to save some break time. It is recommended to try the tutorial prior to your actual exam.
Every student develops their own pace for this exam. Most students have never taken an 8-hour exam, so it takes a lot of practice to develop endurance for this exam. Before the exam, it is recommended that students complete multiple full-length practice tests in order to develop a proper pace.
Strategies for Using Time Wisely
- Be familiar with the test interface before the actual exam. The tutorial can be accessed from the NBME website.
- Time your breaks during practice exams.
- Some students enjoy taking 10-minute breaks between each block. Other students prefer saving up break time for a larger lunch break after their 4th block.
- Sometimes it is helpful to glance at the multiple choices before reading the full question. This can prevent rereading long questions.
The exam contains 280 multiple choice questions in a clinical vignette format. A clinical vignette is a long patient description with associated labs that is followed by a question regarding the case. Each question will have at least five multiple choice options to pick from. In addition, some questions will have two parts.
Sample Clinical Vignette Question

Vital signs are remarkable for a temperature of 104.3F, blood pressure of 80/60 and heart rate of 120. Physical exam reveals a purpuric rash on the patient’s chest. Lumbar puncture reveals a high neutrophil count. What treatment should be given to his roommates as prophylaxis?

The difficulty of each question can vary. The questions can be first, second, or third order. These three orders describe the difficulty of the question and how many mental steps it takes to find the answer. Most questions are second or third order in difficulty.
The score of the Step 1 exam ranges from 1 to 300 with a minimum passing score of 194. The average score in 2018 was 230 with a standard deviation of 19 points. Although the exam is technically pass/fail, students are expected to score high because residency programs receive Step 1 scores.
Step 1 scores are released about 3-4 weeks after the exam. Students receive an email once the score has been released.
