The course assumes no previous knowledge of Bulgarian or any other Slavic language. It uses the Cyrillic alphabet that is taught through side-by-side presentation of English translations and phonetics. The course presents lessons in dialogues, drills, exercises, and English language narration. Each unit is divided into three parts: Basic Sentences, Notes, and Drills, with review units also included. Using both the book and CD's, the student is gradually moved toward proficiency in spoken Bulgarian and its grammar. Level One comes with 23 CD's and a book.
