This book aims to help students check their knowledge and practice in the Language subject. For this reason, it follows the school textbook lesson by lesson, emphasizing grammar, syntax, spelling, and vocabulary.

Each lesson includes:
- the grammar and/or syntax of the lesson
- the spelling of the lesson
- the vocabulary of the lesson (synonyms and antonyms of the most important words in the text)
- multiple-choice questions-exercises.

At the end of each unit, there is "We Speak and Write Correctly," with questions-exercises concerning common mistakes made in written and spoken language.

The answers to all questions are found at the end of the book.
