Due to the fact that I never had any formal lesson in english, I've been had hard times with almost all aspects of the language.
I've been trying to study by myself since I was a teenager and, nowadays, I'm using Ronald Murphy books to cover some gaps in my knowledge.
I can read almost everything (since the begin of year I read five books in english) and, in the past year, I travelled to EUA to improve my listening. This really worked in a lot of aspects, I can understand almost everything in regular TV shows, documentaries and such things, but I don't feel confortable in a lot of situations.
I hope that, with all my efforts, in a near future do a test, like CAE or Toeffel, to certify my English.
