Study Blue - a free flash card system - seems to have many sets of cards on chant that people have created. You may have to join (for free) to login, but it is worth it. In some ways, it is sort of like wiki....you need to think a bit about how people have hooked the answers to the questions and may not always agree, but that's worthwhile too.
