In the lesson 3.1 dialogue, the accompanying text is incorrect. It is written as follows for Maurcio's part toward the end:
No sabía si debía seguir adelante o *al revés*.
It should read:
No sabía si debía seguir adelante o *retroceder*.
I'm still trying to dig up the idiomatic usage of retroceder. I haven't run across it yet in the printed materials.
Also missing nearer the beginning, in Maucio's part, marked in bold text below:
Pero otra vez, la mala suerte, *me perdí*.
