I was afraid to change battery for fear that the new battery may be a lemon and die on me after working fine for a while.Maybe purchase new batteries and put new ones in prior to the exam. Hopefully that will ease the worries of them dying on you
Thanks,

Two days ago I started getting up at 5am in the morning to condition my body. My preparation productivity approached zero yesterday, and has been low, but a little better today. Hopefully my my body will have adjusted by tommorrow and my head will be clear, so I can get 2 days worth of prep in before the exam.
