MOVIES OR BOOKS?

No matter which is your choice, both are perfect to learn more.

Usually we know english because we learn in the high school but most of the time, that´s not enough, then if you read or see movies, you can hear how to pronounce many words, and you will increment your vocabulary.

 All of us know of memory some movies, series, sagas; so start with something easy: see o read what you want, twice in english with subtitles in your idiom, then do that with the subtitles in english, and when you got it, see or read it in english without subtitiles or help.
