This test is unusual for two reasons. First, you take each part at a different stage of your medical education. Second, unlike many standardized tests, the USMLE actually assesses your mastery of the material, not how well you take a test. While there are some test–taking strategies that will improve your performance, you won't pass without comprehensive and detailed knowledge of the sciences, as well as an ability to apply that knowledge in a clinical setting.
The USMLE is designed for students of allopathic medicine , who are on the path to an MD. Students of osteopathic medicine can take either the USMLE or a similar test called the Comprehensive Osteopathic Medical Licensing Examination (COMEX).
The USMLE is divided into three steps:
The Step 2 CS has no numerical score. You earn a "pass" or a "fail" based on your ability to gather data, communicate with the patient and write an effective report.
On all other parts of the test, the number of correct answers you earn is converted into two numerical scores, one on a three–digit scale and the other on a two–digit scale. These are simply two ways of reporting the same result to schools. You must earn a 75 on the two–digit scale to pass.
While your medical school education will give you many of the skills and much of the knowledge necessary to pass the USMLE, you are still likely to log a substantial amount of time reviewing and preparing for each stage of the test.
