Baseis Extra includes the Apology (in Greek and in German translation) and provides working translations of the reading pieces as well as additional guidance for working with the Baseis language course. Baseis Extra ideally supports the course in connecting formal, linguistic, and content-related interests in Ancient Greek. The material presented is reduced and simplified in relation to what is necessary to pass the Graecum examination. Baseis and Baseis Extra are the perfect combination for university courses, study groups in upper secondary schools, and as a self-study course.
