Who knew spare time would be bad?

I'm sitting her in the library at school (hopefully) 3.5 hours away from the conclusion of my graduate academic career... and that's the problem. The way my final night lined up was that I had to give a presentation for my 5 p.m. class and then I have a final in my 7:30 class. This final is nearly guaranteed to be a beatdown to the point that I took today off from work to study. So by the time I got here for the presentation, I was at mental saturation anyways and I just wanted this night to be over. Well there were only 2 groups due to give 15-20 minute presentations in the early class so we finished before 6. That gave me another 1.5 hours I hadn't planned on having to stew about this final. And you know how it goes when you've crammed for something... there's a breaking point where you start confusing yourself or questioning what you know, but regardless, you're not gaining anything. And just throwing in the towel, closing the books, and going to the library to blog doesn't make the final start (or end) any sooner...
