Facebook Apps for SAT Vocabulary Preparation?

<p>Hey does anybody know of any Facebook Apps that can help me prepare for the SAT (esp. vocab)? I only know of one .. this simple vocabulary app that's pretty decent but doesn't have many features:
SAT</a> Vocabulary Words for Facebook</p>

<p>I don't know about Facebook Apps, but FreeRice.com is pretty good with boosting vocabulary. Plus, you get to feel good that you're earning rice for those malnourished countries and all. :)</p>
