Where to begin?

I started with the Ballast/O'Hara PPI ARE Review Manual. This is a huge book, but I figured it was a great resource. It covers all components of each exam. I wanted to get familiar with the exam from a macro level in which I studied the components as a whole. Once I am authorized to take the test, by skimming this book I should know which sections are my strengths and weaknesses. The authors indicate that generally 40 hours should be spent preparing for each section of the test. I will chart the amount of time I spend skimming this material as to keep an accurate amount of time I have dedicated to passing these exams.
