Breath in, breath out, breath in, breath out...

So I'm taking the GRE tomorrow morning. Which according to the offical GRE website stands for:
The Graduate Record Examinations® (GRE®) General Test measures verbal reasoning, quantitative reasoning, and critical thinking and analytical writing skills. The GRE® Subject Tests gauge undergraduate achievement in 8 specific fields of study.
That is 8 specific fields of study folks...8. Should that sound intimidating because it is, it really is. I've kind of gotten to the point where it I am so saturated with information that I can't think. I've been studying for this test all summer and I have come to the conclusion that the sponge of my mind is so saturated that if I try to study anymore then vital equations, definitions and proofs will slowly seep from my mind and therefore be missing when I go to take my test.
It reminds me of a race that I swam when I was about 11 years old. I was always trying to 'pump' myself up but for this race (500 freestyle) I could not wake up. My mind was completely blank and I sat behind the blocks like a zombie, yawning and generally looking like I wouldn't make it to the blocks not to mention finish the race. My coach was worried and trying to wake me up but I just could not focus or even think. Well, long story short, it was one of the best races I ever swam. Don't know why, but it was. So I am really hoping and praying that this will also be the case. That by some miracle everything is there, and when I need it, it will come. That is what I'm praying my little heart out for. Really, I'm terrified but I have faith that I have prepared as well as I was capable and that what should happen, will happen. I'm just hoping that 'what should happen' is that I should be able to pass the dreaded test, go to grad school and fulfill my life dreams. That would be swell. We'll see.
