Directions: Look at the sample USMLE questions below and explore the sorts of questions you’ll face on the exam. The USMLE Step 1 exam questions are in Clinical Vignette format, meaning that you will be asked to pull on information from a number of different disciplines and organ systems and that you will be required to make a number of conclusions based on the limited information provided.
This means if you do not have enough knowledge to make numerous conclusions on a topic then you’re likely to get the question wrong.
You will see below a number of USMLE questions with multiple choice answers. There is one best answer and no negative marking on the USMLE exam, so we recommend you guess if you are unsure or running out of test time.
