Cliques (means: a small, exclusive group of people, especially one held together by common interests) is a social network for university students, to help them connect, review professors, and share academic content. The network is cliques based, hence the name, meaning that users are part of a main clique (university clique) by default, and sub-cliques (college, major, and courses), and they can only post into any clique they are member of.
