Tutorials that illustrate the USMLE Step 1, Step 2 CK, and Step 3 multiple-choice question and Step 3 computer-based case simulation (Primum® CCS) software, sample multiple-choice test questions for each Step, sample Step 3 Primum cases, and orientation materials for Step 2 CS are available under Practice Materials.

The sample test questions are available only for the Windows (PC) operating system because the exams are administered on a PC-only platform at test centers. The sample test questions may run on a Mac that has PC-emulation software installed, such as Virtual PC; however, we do not test the installation or the application running with PC-emulation software, and cannot advise you about Mac applications. If you use a Mac and do not have access to PC-emulation software, you may be able to contact someone who can arrange for the sample test questions to be installed on computers that can be accessed by Mac users or students who do not have personal PCs (i.e., in learning resource centers or libraries).
