Thieme Test Prep for the USMLE: Histology and Embryology 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. "I especially like the clinical focus of the questions, which are two layers deep instead of straight recall." - Deborah Chen (Third-year medical student, Rutgers Robert Wood Johnson Medical School). "Well thought out and also extremely well written. An effective tool for students both in learning the material initially and also in reviewing it for the USMLE." - Roger A. Dashner, MS, PhD (Clinical Anatomist and CEO, Advanced Anatomical Services).
