Confidence in writing Book

I felt as if this book was something that they would use in high school to prep someone for college English. It was very simple and plain spoken. I was quite bored by it as I felt that I learned all of this in 8th grade. Rather disappointed after getting psyched about having an English class, only to find out that I was doing high school review. The class was very slow as one or two people held up the class each day and the reading that was assigned per week was easily done on a lunch break. I can see where this book would have been very helpful to others that struggle with English or someone that has been out of school for many years, but it just wasn't what I was looking forward to. I like to feel challenged in my classes, by my assignments and this book did not fulfill that need.
