I realize it says 'a graphing approach' in the title but I don't think being an expert on using a graphing calculator is the same as learning Algebra. I worked hard and got an A in this class but I didn't use the book to get there. I used my teacher's lecture notes. The instructions in the book were often confusing and added steps that made things more complicated. There also weren't always examples of every type of problem thrown at you in the practice problems. Also, there were errors in the answers and problems. We by no means did all of the problems in the text so there were no doubt more than the 3 I can remember offhand but that's really quite silly considering how expensive the book is.
