Query: a total let down

I have wanted to learn ASL for years and was given this book as a gift and started teaching myself. I thought I was learning fine until I went online to learn a few signs that weren't in the book. I found a lot of what I had learned is not even correct. I was so frustrated that this book is even sold in stores. Avoid this book!!!
