Here is how I studied: I studied for about two and a half weeks.
Read K&B book: When I finished each chapter, I took the practice questions. Then I made a voice recording of myself reading the Two-Minute Drills, any particular things from the text that I wanted to remember, and anything that I learned or missed in the practice questions.
After finishing the text, I took the test on the CD and two Whizlabs tests.
The day before the exam I listened to all of my recordings as a way to review every chapter.
Hope this helps someone else develop their strategy. I have used voice recordings as a study tool for a long time. I highly recommend a digital voice recorder!
