Exhaustion before Midterm

We went down south for a family reunion over Memorial Day weekend and I am exhausted. I didn't study one ounce of material, and I have a midterm this morning in, oh, 30 minutes. Why would she schedule a midterm the morning after the holiday, when it was our first break since spring break in March? This isn't going to be good, between driving 10+ hours each way over the weekend and very little sleep, and no studying, it's not looking too good...
