A good advice I can give you is to start watching movies and T.V programs in English, this will help you to reinforce your audition and even pronunciation. You can also use the subtitles so you will know the meaning of a word that you didn't know. You can start, if you want, with some child programs because the vocabulary it uses is not as advanced as a program to grown ups.You will start noticing your advances, when you can understand more and more the things you watch, you will understand complete sentences and even complete conversations, not just words and that's one way you'll know you're progressing.
