Thieme Test Prep for the USMLE: Medical Physiology is the choice of medical students. The major test-prep resources do not focus on these subjects in detail. A question bank would be beneficial to those who struggle with these as an additional resource for studying. - Ethan Young (Fourth-year medical student, University of South Dakota, Sanford School of Medicine) Very well written in step 1 format, with very good explanations, which is one of the most helpful parts of a prep question set. Succinct but comprehensive in helping me to understand more about each of the other answers listed and easy for me to see why they are wrong. - Chris Moser (Third-year medical student, Alabama College of Osteopathic Medicine) Thieme Test Prep for the USMLE: Medical Physiology from Gabi Waite and Maria Sheakley transforms high-yield concepts into challenging multiple choice questions.
