A free flashcard learning software for ppt-files
OpenCards is a free award-winning flashcard learning software. The basic idea of OpenCards is to use PowerPoint presentations (*.ppt) created with LibreOffice Impress as flashcard sets. Thereby, slide-titles are considered as questions and the slide contents as their answers. Based on state-of-the-art memorization and scheduling algorithms OpenCards will help you to learn any set of flashcards.
