This is the Grammar Book and DVD Bundle. The DVDs are actual teaching disks. The author begins by going through the two basic charts and explaining how to use them. Then he systematically teaches through each lesson. Explanations and examples are given, some of which do not appear in the book. The book has many things going for it. The lessons are simple and direct. The exercises constantly repeat what has been formerly taught. New ideas are approached incrementally in digestible form. The nature of the exercises forces the students to use what they have learned. This is a complete grammar course that teaches how to write good sentences.
