Of course, one excellent way to learn English is to practice with an English speaker outside of class. It would be good to keep your eyes open for an opportunity to do that. A good second choice is to practice with a friend. You can choose a topic and agree to talk about it in English for about ten minutes. Or, you can choose a dialog and practice it together.
