I bought the lit unit for Slacker by Gordon Korman. I sat down to use the questions and was surprised to see the chapter questions and vocab work was mislabled. The questions for Chapter one did not match the novel. Totally useless. And since it is a digital download, no refund. This was not cheap, I paid $24 for gobbledy gook. Won't use this seller again, ever.
PS I only gave it one star because I had to, it doesn't deserve a star.
