Textbook - Level A1 to B1. This progressively structured ASSiMiL self-study course provides an easy introduction to the Vietnamese language and allows you to comprehensively learn the basics of Vietnamese and a vocabulary of approximately 1,100 words in 63 lessons. The course is aimed at beginners who have just discovered the Vietnamese language, as well as advanced learners who wish to refresh and deepen their knowledge. In the initial phase, the focus is on understanding Vietnamese texts through reading and listening (the so-called "passive phase"). With the start of the second half of the course, known as the "active phase" (or "2nd wave"), active speaking practice begins, building a solid language competence. By the end, you will reach the language level of B1; this corresponds to approximately 3-4 semesters at a community college.
