Words cannot express how awful this textbook is. About 30-40% of the answer key are wrong answers; the "errata" website that is supposed to list the different errors is mysteriously down, so if you need to check your answers, you're going to be SOL.
Homework questions are ridiculously long and drawn out.
Honestly, if someone asked me to rate this textbook 1-10, I would beat them up for expecting that this book is even worth a 1.
