Grammar and More... scores over traditional grammar books in terms of vastness (over 2000 pages) and effective use of the "Three I’s" (interesting animations, interesting explanations, interesting example sentences and quizzes).
Traditional grammar books have long been used to teach grammar in schools and colleges. Such books reinforce the belief that grammar is boring and requires learning by rote. The lack of alternatives has forced students, writers and professionals to resort to outdated grammar textbooks or "free" online material in order to improve their writing and comprehension.
Due to the lack of formal training in English usage, most of us use what we feel sounds right. With Grammar and More... we can write authoritatively and avoid elementary mistakes if we learn grammar in a structured manner.
