Study idea for Saylor

Saylor.org is an amazing resource with awesomely crafted classes. However, a lot of what is available depends upon memory. Easily mobile made flashcards or quizzes would be amazing. I think it would be very cool if Saylor partnered with Quizlet on something like: https://quizlet.com/upgrade?source=black_friday_sale_banner&showTeacher To make sets available and have study cards available.
