This goes toward the point about repetition:
AUDIO FLASH CARDS"
I found that using visual flash cards involved a lot of preparation time and I tended to drive dangerously when studying/reviewing on the way to school.
Instead, I purchased a CHEAP digital recorder (now they are free as apps for smart phones!) and imported everything to iTunes to make AUDIO FLASH CARDS. These were formatted as Question / Pause / Answer and I would group no more than about 10 questions per set.
I would assign the iTunes headers to my own structures: i.e., "Album" became "Class", "Genre" became "Body Region", "Artist" became "Discipline - Cardiology, Pharmacology, Ortho, etc.".
To use the "cards", it was only necessary to select what was to be reviewed and keep my hand on the play/pause button of my iPod. By the 3rd or 4th pass, I would OWN the material.
I found that by using smart playlists in iTunes, I could review by exam, class, test, discipline, body region, etc., and I could make use of my driving time without worry of causing an accident.
I now talk about this to each class, and (for those who are interested), show them how to do it.
