it was through audio tapes. it was easy, but to become fluent you need more exposure.
learning a new language becomes easy if we listen to the conversations of people speaking the same language.
continuous speaking of the language we want to learn will help a lot.
i am fluent in the language.
teachers and textbooks
there is no better way to learn a language than by going to a country. i used to have good english teachers, but i hated learning this language until the day i went abroad. we focus too much on grammar in school, but we should focus more on listening comprehension because it is when you hear an expression (that comes from a local) that you try to use it afterward.
