<p>Biology</a> - Science - Brightstorm
These videos are awesome, our teacher showed a couple of them to us at the beginning of the school year. The guy in the video: "Stanford-educated Patrick Roisen has been teaching AP Biology for 12 years, and at least 80% of Patrick’s students pass the AP Biology exam every year." These videos are soooo helpful and clear cut. Plus Roisen is funny. :)
EDIT: khanacademy's channel on youtube also has fantastic videos. go to the playlists on its channel and biology should be first. there's also chemistry!</p>
