tiring pace

I've finished one of three exams and I'm taking a short break from the books for #2. This is very mentally draining. I'm disappointed with my first exam, I know I'll do much better on #2. The third is crucial that I pass. The pressure is building, but I have to make it. Everything rides on this and my ability to pull through. 4 weeks left...time to break out the keg of whoop-ass.
