I found that flash cards were extremely high-yield. I was able to jam a lot of this kind of useless information (and much of it stuck) with flash cards. As a PC user I am partial to Mnemosyne (
http://www.mnemosyne-proj.org/) - its open source freeware. Though it takes a little tweaking to get it to work well, once it's up it's very powerful. It uses an algorithm based on the Leitner principle - you self-score your recall of a card from 0 (I don't know it at all) to 5 (I know it cold). The algorithm increases the frequency you see cards you rate low so that you don't waste time on the stuff that you know. I have also heard good things about iFlash if you are Mac-inclined.
To study for the CP boards I made over 1000 flash cards (they are easy to make), some with photos (D-test, fungus morphology) and some with just organism on one side, fact on the other (What are the members of the strep viridans group?, etc). The simpler the card, the better.
If you have any more questions about the cards or study techniques, drop me a PM or post away.
