When I was in 7th grade I first purchased this book, and I have used the guidelines outlined in it ever since. There is quite a lot of valuable information packed into the book! There are sections on Basic Grammar and Writing Elements, the Art of Writing, Personal Writing (such as in a journal), Subject Writing (such as a news story), Creative writing (such as poetry), Thinking skills, etc. One of the most helpful parts of the book is the "Yellow Pages" section, which is basically a grammar tour de force that explains subordinate clauses and other potentially difficult elements of English Grammar. Perhaps the most useful part of this section is the "Using the Right Word" section. It has commonly misused words, such as "Effect" and "Affect." It has each word properly defined and used correctly in a sentence as an example. Finally at the end is a tables of weights and measures, a periodic table, a Morse code alphabet, a world map set, historical documents such as the Emancipation Proclamation, etc.
