You get 2 review books: "General Principles" and "Organ Systems," and a question book. "Review" is actually a little misleading as the material is really extensive and a lot of it, extraneous. As far as I'm concerned, there just isn't enough time to go cover to cover with both of them, e.g., I started the neuro, immuno, and behavioral science sections last month and haven't even covered 1/2 of the material yet -- and this is without the MS2 classes?! I would save my money if I were you, although the question book looks promising.
I think I'm gonna stick with "First Aid" and some of the high - rated review books, as they seem a bit more doable. Hope this helps.
