Looks good. I know the majority of the authors have written the books in the high yield series. I believe barbara fadem is the author of the high yield behavioral science, ron dudek is the author of the high yield histo, anatomy, and embryo. All of these books are really good for board prep. But, that is the first time I see a High yield comprehensive step 1 review book. It looks new.
I didnt care for HY as much as I did for the Lange books, even though they are much longer. I probably didnt use a single one to study. I did have a big Princeton book as a reference, and I probably would have rather had this one. Looks pretty good.
