Here is how I think of learning languages. There are two skills and two areas of study. The skills are listening and speaking. Just like any skill, like riding a bike or playing badminton, listening and speaking require practice. They are also pretty fun, once you have a little bit of ability. I'm never sad that I must play basketball or football. They are fun. There are also two areas of study: vocabulary and grammar. Just like any subject, like math or science, they require books, study, notes, and review. Vocabulary work should be done daily with a flashcard program like Anki. Grammar work should be done in small doses, but at least every week. Then your practice ... the fun part, listening to music, watching movies, or talking with new friends, let's you put your new vocabulary and grammar skills to use. So, in my opinion, you don't have to pay for a class ... but you have to study. And you must practice!! And have fun doing it!

if you wanna learn regular i think you should go to english class if you wanna learn irregular i think you should listen to english music and watch TV i thing both of them are important to improve your english

Just imagine that you are in command of the language when you speak it and see the difference.
