Do you study the day of or night before your exam? Take a day or two off, etc?
I'm wrapping things up for my switch exam. Test is on Tuesday. I would say at this point I'm ready to take it. Finding it really hard to review things, just a bunch of words to me now and I've never done so good on practice exams as I don't concentrate like like when taking the real thing. Back when I was taking Cisco tests in 04/05 I remember this was one way I was able to gauge test readiness, so hopefully that's still the case!

EDIT: I just rescheduled my test for Monday, I didn't know it would let me do it so soon before the exam. No need to waste anymore time waiting...Do or die!!!
