FunnelBrain - answers, questions, flashcards

About FunnelBrain: "FunnelBrain.com is an academic question and answer site that provides an environment for collaborative online learning. Students work in teams to create review questions and answers, paired with video explanations, for academic subjects. Users have access to wiki-style content creation tools, as well as a learning management application known as the 'Funnel' that tracks and monitors learning progress and focuses the student's attention on a particular question at a particular time with a spaced repetition algorithm. The FUNNEL is a learning application that manages the review process to make it as efficient and effective as possible using a spaced repetition algorithm that presents the right question at the right time. The FUNNEL makes sure you spend most of your time reviewing the questions you still need to learn, instead of the questions you already know. The FUNNEL can do this because it knows the last time you reviewed each questions and whether you 'got it' or 'missed it.'"
