First of all, to Mpangel99, You wrote "The only complaint I have for this book is that there is alot of worksheets before a test"... I think that you really need the worksheets. Worksheets is plural therefore the word "is" should be "are" bringing me to the word "alot" which is not a word but in fact two. The sentence should read, The only complaint I have for this book is that there are a lot of worksheets before each test. Secondly, I found all the reviews to be very helpful and will be purchasing this item.
I can't say enough good things about this book. My daughter was behind in grammar and this book is very self explanatory and easy to follow. The explanations are concise and to the point and the assignments are well thought out and build on each other. If you want your child to really master the English language you can't go wrong with this book.
