Free, downloadable books are the best imo. This site sends 11 books to your email in hopes you’ll realize at some point that books are not enough and that you’ll start practice speaking fluency with the help of an online teacher.

The books are great resources to get you started but what’s the point of being literate if you can’t talk to anyone?

Take advantage of the free resources where you can and save money to put towards really being able to use the language and hire a personal tutor.

Good luck with your studies, my friend.
