Query: If only I would have purchased this book sooner.....

When I first received this book I was going to send it back; but the more I compared the context of it to the words I messed up on my Medical Transcription papers, I realized that if I would have had this book at the beginning of the course I would have gotten my papers correct. I recommend it, you will use it.
