Hello!
I saw that are almost all of the posts already commented (except the one from Mojca (there is no mistakes))   so I decided to write post except of the comment. I will write about pages where you can learn English ''free''. I saw many different pages and realized that some of  them are very boring. On other pages you can learn a lot about English on interesting and a fun way. But you have to work every day and work hard if you want to learn a lot of English. For our class I think the most suitable page is for improving English. On this page there are some strategies how to improve your English :  http://www.learnenglish.de/improvepage.htm
And here are few rules for improving English:

• Join an English course - a virtual one or a real one (and attend regularly).
• Do your homework.
• Read a book or a comic every month.
• Learn a new word every day.
• Visit an English speaking forum every day.
• Read a news article on the net every day.
• Do 10 minutes listening practice every day.
• Watch an English film at least once a month.
• Follow a soap, comedy or radio or TV drama.
