Title: Critical Errors- DO NOT BUY
Review: This book is rife with errors and mistakes, an in critical ways. For example, one question, on a fairly basic topic, asked what %age guanines are in a DNA molecule (double-stranded) that contains 20% thymines and 30% purines. Given that guanine is a purine, and adenine is a purine, this implies that the breakdown is as follows: 20% A, 20% T, 10% G, 40% C. This is clearly impossible, as that would not be a stable molecule.Other idiotic errors abound, but I provide that as the absolutely worst examples. This book leaves me with absolutely no idea how well I will do on the GRE, and has basically been a useless study aid. I find myself correcting it far more often than it corrects me.
