This is one of the worst textbooks I have ever read. The only reason I bought it was due to my C.S. class. However, I quickly learned to hate it. While I can understand the chapters, the questions are overly difficult and have nothing to do with real-world applications. There is no way to apply your knowledge or find out if you are inperpreting the text right.Even with programming knowledge, this book was still hard to work with. You can do better than this one. I'll be pawning this book...
