Hi Mair, you could visit the website
www.mylanguageexchange.com
There you can learn a language by making an account and give information about what language you want to learn, and what language you can teach to others (probably your native language). Then you can find someone through this website who, for example, is fluent in arabic and wants to improve his/her english. You can then learn from each other (also a nice way to make new friends).
