Auténtico has multiple resources to help students learn Spanish. There is a lot to teach vocabulary words, lots of listening activities, lots of culture, including videos, as well as reading and writing. It has IPA's. I think having an app that students can use on their phones is also pretty impressive. I like that the pruebas have automatic remediation. The navigation can be difficult without teacher help. The book is easier to use than the LMS which can be extremely hard to navigate.

Autentico is truly a great source of knowledge. They organize the content in a very user-friendly way and the digital tools allow students to naturally participate in the activities at their own pace. One of my favorite things is the integration with Google Classroom and teacher management pages, the progress visualization works really well. Without a doubt, this is a book for Spanish learners that is highly recommended for its content and the integration of technology it provides.
