The English Grammar Practice series of textbooks is designed to develop student understanding of grammatical concepts from beginner to advanced level. The textbook series may be used for independent study as well as in classrooms and online teaching. The textbooks contain grammar explanations followed by a variety of exercises to develop grammar skills. All exercises are provided with an answer key at the back of the book with the correct or model answers. There are four levels in the series: Beginner Level, Elementary Level, Intermediate Level, and Advanced Level. The textbooks are meant to be used progressively from beginner to advanced level. Each level builds upon knowledge from the previous level. Students may, however, begin from any level depending on current grammatical knowledge or their topic of interest, as may be found in the table of contents of each level. In the advanced level, you will build upon the knowledge gained in the previous three levels to further refine your understanding of English grammar and solidify your understanding from the previous three levels to be able to communicate more difficult concepts and opinions. After completion of the previous three levels and the advanced level, you'll be able to communicate in a variety of situations using grammar correctly to express your experiences, thoughts and opinions, whether in written or spoken form.
