With the eighth edition of First Aid for the USMLK Step 2 CK, we continue our commitment to providing students with the most useful and up-to-date preparation guide for the USMLE Step 2 CK. The eighth edition represents a thorough revision in many ways and includes: An all-new color design for better learning. New, innovative flash cards embedded in the margins to reinforce key concepts. Hundreds of new color images and illustrations throughout the text. A revised and updated exam preparation guide for the USMLE Step 2 CK that includes updated study and test-taking strategies for the FRED v2 computer-based testing (CBT) format. Revisions and new material based on student experience with recent administrations of the USMLE Step 2 CK. Concise summaries of more than 1000 heavily tested clinical topics written for fast, high-yield studying. An updated "rapid review" that tests your knowledge of each topic for last-minute cramming. A completely revised, in-depth guide to clinical science review and sample examination books. The eighth edition would not have been possible without the help of the many students and faculty members who contributed their feedback and suggestions. We invite students and faculty to continue sharing their thoughts and ideas to help us improve First Aid for the USMLE Step 2 CK. (See How to Contribute, p. xiii.).
