Education sites exist to offer an online learning platform for those who prefer pursuing further studies or short courses in the comfort of their own home (or wherever they prefer to learn). It’s an offshoot of distance learning. Online education is the next logical step to correspondence learning where students receive course materials by mail. Today, even the traditional materials involved with knowledge, such as textbooks, examinations and quizzes, and lectures are mostly Internet-based.
There are different kinds of online education sites, including ones for users who want to complete a degree online or to supplement their knowledge of specific subjects to help them seek better careers or employment. There are also learning sites that specialize in reviews for specific examinations to get certification in particular industries and institutions.
