This review book is Amazing!!! provides a concise review of the biostatistics concepts that are critical for the USMLE Step 1 exam. As an international medical graduate who has not reviewed basic biostatistics since the first year of medical school “over a decade ago! “, I needed something that helps me rebuild my knowledge from scratch without overwhelming myself with time consuming, low-yield concepts. For that I’ve found USMLE biostatistics to be the book of choice. Unlike most resources that are available in the market this book is written in a very easy-to-follow format, rich in High-Yield points that help me focus on the most important USMLE Step 1 facts and full of colored graphs that make the clinical vignettes look like a piece of cake. Author’s note: The USMLEbiostat workbook is also applicable to CK!!!
