Falta de boton guarda el avance

I don't know if the OP can read this, but assuming this is Spanish, and Google Translate was able to interpret this properly, but I believe you're asking whether there's a button you can press to save your progress in the course. The answer is, you don't need to do anything to save your progress. It keeps track of what page you were last on automatically, so when you reenter later, it prompts you to return to the last page you were on.

El programa no guarda progeso, yo creo que lo unico que cuenta es que pases el examen.
