OXFORD TEFL – http://www.oxfordtefl.cz/
All English levels available!
Really cheap and best quality! I prefer qualified native speakers than teachers in training, but you have to find your own preferences 😉
You can try it, even for two weeks.
My advice: Start with level test and find out about your level
When I started going to OxfordTefl I was at level A2 and thanks English classes and my efford during school year, I am now at level B2, I would like to pass english certificate – FCE this winter, so please cross your fingers for me! 🙂
And how did It happen? My big improvement?
I started watching movies and series in English, at first with czech subtitles, than with english subtitles and now I do not need them 🙂
Of course a big help for me also was reading, I started read simplify reading – Peanguin readers edition and after some time I red Harry Potter in original English edition! 😉
