The book itself is ok and has mistakes like the other reviewer mentions but that is bearable. It is the 2 online exams you are supposed to get that gets me irate. It's not a simulated test but rather a random set of 16 questions or so on 2 tests each. Beyond, that even with the code I was not able to initially access the online tests and then had the torturous experience of getting help from Lumos on unlocking the tests. I will not be purchasing Lumos products again and hope you spare yourself the experience too.
They have so much mistakes in this book. For example one question asks “ where is the dog in the first sentence of the story” when the very first sentence seems to be edited out from the story. Too bad because otherwise good practice book.
