Query: An excellent resource for adults and teens alike...

When I was in college, I had a roomate who was constantly correcting my grammar. The habit wore off on me, and while mine is not perfect, I do like to think it's good. I bought this book to answer several nagging questions I had about a few things, and was very impressed.The format is laid out well. The lessons are simple and easy to follow, while conveying information thoroughly. This book can be used by adults as well as teens in high school to great effect. And like, it's never a bad thing to tawk gud, ya know?
