Listening to music in English can be an effective way to learn. Also watch online videos, movies, tv shows in English.

OK, there are a few ways you can do it on italki: - chat with other members in English - ask questions about anything that confuses you (ie. here) - practice writing using the Notebook section, AND read other notebooks. You can learn a lot from the corrections given to other people. - the hidden gem: www.italki.com/knowledge Lots of information there. In general: - look for short online courses and tests. There are plenty of free sites for this. - search out other sites to chat with native speakers and practise your writing. - sing the songs and speak the dialogue from movies and TV shows. Watch and listen, but also imitate. - read. A lot. All through this, TAKE NOTES. Have a pen and paper next to your computer. I seriously advise planning to take a proper course (not a free online course) or take proper lessons from a teacher in the future. You may manage OK with free information, but there will be holes in your English knowledge, and you'll still sound very limited to native or advanced speakers. Don't worry; it will be worth your while... and I am speaking from personal experience here. :)

Find a native speaker on italki and practice your English with him/her :)
