Have you ever thought of using your MP3 player to learn? You might be surprised to know that there are free podcasts that can help you with your school work, such as Douchy's Biology. You can listen online, but better still you can put the episodes on your MP3 player and listen while you are on the move.

If you don't do Biology, do a Google search for podcasts for a subject that you need help with or check out educational podcasts in the iTunes store. Sometimes it takes a while to find a good one so don't give up too soon.
