The exam lasts one day. Multiple editions, or "forms," of the exam are used, and they may differ in question order and content. Some questions require the interpretation of illustrative materials such as electrocardiograms, radiographs and photomicrographs (e.g., blood films, Gram stains, urine sediments). A list of normal laboratory values is provided. Refer to this list to interpret values given in the questions because they may differ from those to which you are accustomed.
