Has some errors, and some areas are way to detailed for what you need for the USMLE
This book is advertised as being 128 pages, but it is actually only 104 pages (which includes 2 blank pages). There are some charts/graphs/tables that really aren't necessary for the book, but were probably added to try and pump up the page count. In reality, all the biostats you need could be covered in 50 pages or less (including some practice questions), but I suppose the author and publisher couldn't justify charging $29.95 for something that small.Worst of all, I found a few errors. I'd list them here, but then I'd feel like I'm working for free for the author and publisher.
