you can do all kinds of things to "batch" things. Like make it all in ice, or jello, or water, etc etc. however most of the time it isn't too much of a problem if you want to repeat memorization in short period of time if the things you are remembering are different. So when trying to remember something like cards it can be problematic without adding something like above.
