Conversation practice with a native speaker will improve your comprehension and ability to generate Spanish naturally. First, find a partner using ConversationExchange.com, Craigslist or LiveMocha (available for free online and through many public libraries). Start by meeting one hour weekly (30 minutes in English and 30 minutes in Spanish) and offer friendly correction to your language partner.
Remember always to exercise caution and good common sense, and meet via Skype or in a public place such as a café or park.
