Dear Ranja
I am not sure from which country you are from, however, there are many English Universities that offer a distance learning Masters in English Literature.
They all require that you have at least IELTS, (which is only valid for two years!).
You need to be carefull that you chose a course which is within your level of English as some are very difficult.
Avoid any American courses as they are cheaper but not true English!
You have to be prepared to read a graet deal so this will take a large amount of your time.
Taking this degree can be quite daunting, however it will be worth it in the long run.
If you need any further help after you find the course which you feel will meet your needs fell free to ask anything further.
Regards
Mike
