CheatSheet for Windows 8

Cheat Sheet is a digital knowledge base that collects the most important and interesting information for each subject and category. All categories (history, biology) are composed by short articles that describe an event or a topic. Categories are divided in subcategories (e.g.: Special habitats - surprising adaptations and Plant or animal for Plants). Each article is illustrated with at least one picture, and most of them contain external links to the most relevant online encyclopedias.
