Let's Cram, a Facebook application designed to help high school and college students do their homework and study for tests, just nabbed $185,000 of an anticipated $400,000 in seed funding, according to regulatory filings. The Santa Barbara, Calif. company could not be reached for comment, but the investment came from local individuals, including the company's founder, Michael Lewis, and Patrick Dietzen, co-founder of biotech firm Sirigen.

Let's Cram uses every social-networking trick in the book to connect students who might be able to help each other in school. For example, users can post homework questions to forums and await messaged replies, view which of their study buddies is online at the time and available for chat, and create groups and forums for specific classes. There's even a link to recommended procrastination activities. You can take a video tour of the product here.
