I like using memrise.com. It's a great site for learning new words. Working with a language partner is also very helpful. 

Many English learners who learn English as a second language, have negative experince from schools and you must search for new techniques to learn. these are some which i found on the internet

to improve your speaking fluency

- Don't study grammar too much

- Learn and study phrases

- Don't translate from your native language

- Reading and Listening is NOT enough. Practice Speaking what you hear

- Submerge yourself

- Study correct material

the whole topic is in this link

Read a lot. Then listen a lot. Then speak a little, and you will have excellent English. 

Few days ago after long search around internet I found really great and fun way of studying English. I enjoy the fact that without learning grammar you somehow start understand what and how to use it. I recommend this e-learning course to everyone who wants to straight up their conversational skills. Heir is a link http://www.bellsenglishonline.com/
