Web sites such as Cramster aim to revolutionize the way students study, much the way that networking sites like Facebook have changed the way people socialize.
Course Hero, launched last year primarily for college students, already holds a library of more than two million course documents, including homework, class notes and graded essays, uploaded by students enrolled at 3,000 different colleges. Koofers (a nickname at Virginia Tech for old tests passed around at fraternities) allows students from about 25 state universities to submit posts about the difficulty of courses taught by different instructors at their schools. It also offers average semester grades from instructors. Enotes, geared mainly to high-school students, allows peers to form discussion groups and pose questions to experts -- usually teachers -- who are paid by the Web site.
