I believe there is also a 1001 Questions in Biology book too. However, I recommend the regular Examkrackers. They have it for the Bio/Gchem/Ochem. Great to use as references and it gives great details and pictures on certain concepts that hard to understand or not explained well in the Kaplan book.
i do recommend the reference books also but if u can look at them at yuou local B&N while you studying you don't need to buy them (they are expensive 100 +)
