Hello Fernando! I decided that for me, for example, very important speaking practice, but it's very difficult to find somebody for practice! Also I use some websites: * voice of America for learning English * ororo.tv - there is many movies and serials with subtaiters. * elllo.com - for understanding non-native speakers * "English in Use" - my favorite Englsih book. I don't have special schem, I use this websites for improving my skills.
