Grad school: Slightly stressing

I just got word earlier this week that my paperwork for GRE accommodations has been sent into ETS. I have no idea when they'll get back to me, but I have a little over a month before the deadline that my scores need to be in. In that, I have no idea if I'll even have enough time to look over things, especially the math. ETS won't send me practice materials until my accommodations paperwork is received, which I do understand. To any of you who have taken the GRE, is it super hard? How much should I be stressing here? Part of me wonders if I should scrap the plan for entering in the fall and shoot for the fall of 2010. NIU would hold my application until then, or so I've been told. Doing that would mean more time for studying, but I wouldn't know what to do with myself otherwise in the meantime. I guess I would stil continue to look for a job, but then I'd hate to get a job only to have to quit a short time later due to school. So yes, I'm in minor stress mode here. I really would like to shoot for taking the test before the deadline, but that'll depend on when I hear back. I could just take it and hope for the best that I get the necessary score, but I don't think I should just take it without properly studying beforehand. I also think that might be way too ambitious and a recipe for failure. What have others of you done? Am I completely overthinking things here? If you couldn't tell, standardized tests and I don't mix well, at all. This is going to drive me insane! I know things will all work out how they're suppose to and whatever is meant to happen will, but regardless, that logic isn't really helping me at the moment.
