<p>Hello.</p>
<p>I am going to take GRE Subject Test in Biology this October. I am trying to buy some prep books for GRE Biology but I heard that prep books like Princeton Review and Kaplan are not good for GRE SUbject Test...I am wondering which prep book should I choose to prepare for GRE Biology test? Are AP Biology prep books like Cliff Notes sufficient for GRE Biology?</p>
