Aula Internacional - 4 Plus |link|

Explanations are entirely in Spanish, requiring high B1 reading skills to start.

Each unit integrates the key innovations of the Plus edition, including the "Construimos el léxico" vocabulary builders and the expanded grammar sections. The course also includes a final "Más gramática" section that consolidates the key structures from all units for easy reference and review.

Ultimately, Aula Internacional Plus 4 is a powerful, versatile, and contemporary tool for learning Spanish. Its thoughtful, community-driven improvements have made a highly effective series even better. Whether you're looking to refresh your teaching materials or use a top-tier B2-level textbook for your next course, this book is a top contender. However, for optimal results, it is best used in a guided learning environment, perhaps alongside a more traditional grammar resource for reference.
