Grockit is an online social learning game company. It currently offers GMAT and SAT test prep games. Grockit believes that people learn better through peer-to-peer situations instead of teacher-to-student, and they are building their companies’ products around this idea. Grockit is a play on the word ‘grok’ which means to understand something so well it becomes part of you. Their main competitors include online courses offered by The Princeton Review and Kaplan.
