One of the most effective ways I remember studying for vocabulary quizzes in high school was through flash cards. During my time in college, I wondered why a similar method was not used to help study for other things, particularly in classes where new definitions and concepts are introduced everyday. As a result of this, I wrote an initial flash cards script to help me with my advanced calculus class. Because of my success in this class, I continued developing flash cards to help study many other concepts. Here, I have decided to share some of those concepts with you.
The AMS Graduate Student Blog lists some other sites where you can get math generated flash cards.

I found that the flash cards were not working in firefox and modified the code to correct this error.
