Welcome to the newest edition of MKSAP for Students. The fifth edition of this popular series contains over 450 completely new multiple-choice questions, updated references, color photographs and ECG tracings. MKSAP for Students is intended for third-year students participating in their required internal medicine clerkship and for fourth-year students on an advanced medicine clerkship. All questions are formatted as clinical vignettes that resemble the types of questions students encounter on the examination at the end of the clerkship and on the USMLE licensing examination.
