One addition to my lessons learned.
My brain dump consisted of the Process Group & Knowledge area mapping on page 61 of PMBOK and the formulas. The forumlas proved more useful than the process group mappings as I had numerous questions on earned value and a few on 3-point estimation as well. It was nice not having to recall them during the test, but to have them already written down in the format and order in which I was able to memorize them. As stated by many others, know what you NEED on your brain dump and practice writing that information until you can duplicate it flawlessly and quickly! It took me 3-4 days to get the process chart, then I added a few of the formulas until I was able to get the chart plus the formulas, and every few days I'd add a few more formulas until I had them all.
