If you havent already I would recommend buying the Vango notes for the Brady Prehospital Emergency Care book we have. It covers all chapters, and has practice quizzes at the end of each chapter review.
It is an audio study guide but does not read the entire chapter to you. Each chapter runs about twenty minutes and covers important definitions, and various key topics.
When you visit the site you can buy each chapter individually or you can buy the whole book at a discounted price of twenty dollars. You can then go back and download each chapter to your MP3 player, play them via their own player on your computer, or as I understand it, burn it to a CD to play at home or in your car.
Just a tip though. I would recommend reading the entire chapter before going over the Vango notes. It is a guide to help you review what you have already read. It will not substitute reading the chapter for yourself.
