This comprehensive English course is designed for children in Grades 7 to 9, for advanced ESL students, for Grade 10 to 12 pupils who need more practice with basic skills, for students who study at home, and for adults who would like to learn advanced grammar and increase their general knowledge of the world. Every chapter consists of grammar, reading comprehension, phonic spelling, vocabulary, conversation, writing practice, and general knowledge. At the back of the book are several extra sections including conversation topics for ESL students, extra writing topics, a phonics summary, dictations, a booklist, and answers to all the exercises. This book is based on the "Essential English" series, but is an updated version, in a better-bound, larger format and with the addition of general knowledge.
