I am also using it. I had it lying around from my AP bio days, so I decided to use it.
I wanted more in depth info than Kaplan, so I started studying from my physiology book, and Schaum's Bio. And then I started Cliffs AP bio, which im my opinion is less convoluted than schaums, and it goes in the same depth. And my physiology book goes too much in depth. So, It is much easier to study with. I would recommend this also. 🙂
