Microsoft Flashcards, is the latest project from Microsoft Education Labs. Flashcards is a tool that helps you create, share, and most importantly, study more efficiently.
Flashcards offers a unique learning experience that you don’t get with traditional flashcards. Cards that you have never studied before are introduced at a rate that is customized for you; it will introduce new cards more often if you show that you know the previously introduced material, and it will introduce new cards less often if you still need to learn some of the previously introduced material.
The order in which cards are reviewed is also customized for you based on how well you know the cards. Over time, cards that are easy for you will be displayed relatively less often, while cards that are difficult for you will be displayed relatively more often.
Finally, your progress is all saved in the cloud, so you can study from home as well as from school and the system will use all of your previous progress to determine the best order for you to study. The end result is actually kind of fun.
You can also login with your live id and create your own deck.
