Below are links to a few reliable web pages to use in preparing for quizzes and exams.
Freeman-pedia.com is the mother site of all things AP World. Visit it often. It will has resources that remain unparalleled on the web.
Jay Harmon's AP World History Page is another helpful resource, especially if you would like some practice APWH essay questions.
Here is the link to the Crash Course World History playlist that is put out by the guys at Crash Course. These are pretty nice and concise videos over the many topics that we will cover in class. Spoiler alert: John Green talks SUPER fast.
Another great YouTube channel you may want to check out is Heimler's History. Great channel that breaks videos down into the Units that we will be studying this year.
If you like videos, another YouTube channel to check out is Overly Sarcastic Productions. Their "History Summarized" videos cover a variety of topics that span all of history. While I cannot vouch for all of their content, the history videos from the "Summarized" section are pretty good. Plus, the narrator doesn't talk as fast at John Green or Steven Heimler.
