Query: Excellent text!

I love this book. I didn't get the chance to go through every single page but from what I've seen, this book is a must have for people who's English much sucking. I'm one of those people who gets tripped up by tenses of verbs once in a while on a grammar test. However, my grammar is still excellent in usage and writing. But I still know better than to fire my proofreader.
