I took the course using the text book and found it very easy to follow. It had good, relevant content. I was able to read through it and pass the test in one afternoon. I liked the text book format because I could mark it up as I went along, which allowed me to highlight key areas that would be covered as part of the test.
I purchased book only, and it was great. I think it is very informative, interesting, easy to understand and read book. There are many different topics covered. Also, I found example cases and review questions after chapters very helpful. Would recommend to get this book. Thank you.
