I should probably be ashamed to say it....but I have been working towards this for about 16 months...but NOT because it is giving me that much trouble. I, too, am trying to find permanent work but have been fortunate to have two long periods of contract work with a company near the space center here in Houston. With that work, I studied, then took a while to let my head clear. I am not wanting to pass by ramming answers in to my head, I want to pass by knowing the material and the concepts behind it. I'd rather make a 90 and know the material well than have 100 and forget the test answers in a months time!!!
But, like you, I am getting close to calling and scheduling the test...
