Hi all - I copied/pasted screen snips of all the quant flashcards from the GMAT Club deck into a deck for Anki. I like Anki for flashcards because a) it automatically determines frequency of repetition based on ostensibly sound learning theories and b) it syncs your progress across PC software, web-app and android/iphone app. Nothing says devotion like drilling overlapping sets while on the can.
This is the first time I've shared an Anki deck, so please let me know if I botched it. The tags might not be great since I don't use the tags function, but I figured they might be useful for some so I threw em in.
I can't link to Anki but it's well known enough that a quick google will turn it up.
