Want to practice and get input without any effort whilst doing other things? Then listen to the radio. Have it running in the background whilst browsing the web or ironing.
I mainly flip between listening to two stations, the Taiwanese station RTI and the French based rfi. Both are great resources. The French one covers international topics and uses a standard, easy to understand dialect, as does RTI.
The Taiwanese RTI station also has a variety of programs including plays and phone-ins.
I find that phone-in shows are the most interesting and easy to understand because you get a host of different accents and you hear oft-repeated phrases such as greetings and salutations.
Add listening to the radio to your list of Chinese resources for easy course credit.
