I know a lot of people suggest not studying on these last couple off days before the exam, but I could never do that. It was easier for me to study than it was to pretend that I was relaxed!
So, my recommendation for today and tomorrow is to do MBEs for about 30 minutes, review Jason's outlines (if you have them) for one of your weaker subjects for about 30 minutes, then take a break for about 30 minutes. If you do this, these last two days will fly by and you'll keep the material fresh in your head.
Also, do not stress out about memorizing the rules. The graders are not looking for perfect rule statements - they're looking for solid analysis. On my last exam I spent much less time agonizing over the rule statements and much more time thinking about the relationship between the facts and the elements of the rules.
Best of Luck to All!
