The only sliver of hope I have is I remember feeling this way my second week of class, when I started working with the x-ray tube in the lab. I worried that I was one of those book-smart people who couldn't transfer that knowledge into action. But I practiced and I learned how to use the tube. I choose to believe the same thing will happen with my exams, that practice really does make perfect. I should probably, as always, cut myself some slack.
I just had to get that out so that I would have some hope of sleep tonight. And on that note, I am going to bed because tomorrow's another chance to improve.
