These "500 questions, answers, and explanation" books are designed to simulate the United States Medical Licensing Examination (USMLE) Step 1. Each is authored by an expert in the field and has been reviewed by students who have recently passed the exam. As Step 1 is becoming increasingly more clinical in nature, when applicable, clinical vignette-style questions requiring a two-step reasoning process are also included. All of the Pretest titles include a "high-yield" fact section to reinforce key concepts.400 clinical vignettes covering all the basic sciences8 blocks of 50 questions — just like the USMLE Step 1Content reviewed by students who recently passed the USMLE Step 1PreTest is the medical student's most dynamic weapon for mastering the USMLE Step 1Simulates the actual exam, question by questionReviewed by recently tested studentsPreTest is the closest you can get to seeing the test before you take it.This one-of-a-kind prep guide simulates the USMLE Step 1 to help you:Get to know material likely to appear on the examPractice with 400 timed, clinical-vignette style questionsBuild confidence, skills, and knowledgeFind references with every answerThere are plenty of answers out there.
