During my GMAT preparation, I made close to 300 flashcards to help me stay fresh on the strategies and materials I had studied over the course of several months. The document linked below contains the digitized version of my flashcards--please use them as a study aid.
Also, seriously consider making your own deck of flashcards for your own studies. You will be surprised by how much you commit to memory by simply writing down concepts on paper.
Best of luck!
