The crazy thing about Caltech is that for most students, not sleeping is part of the culture :) Maybe this is actually true of college students in general (staying up late doing absolutely nothing) but at Caltech one usually has to stay up late doing problem sets. So, sometimes, on the occasion that you are done with all of your sets early, and have the time to go to sleep at a decent hour, you actually don’t. In my case, I stayed up later than usual (4am, I usually go to sleep promptly at midnight). On top of that, we had to register for classes Thursday morning at 8am, and so I woke up at 7:30. Registration begins at 8, but I think you actually have 2 weeks to go online and complete this task. However, there are some classes which have limited seating (only 20 students are allowed to sign up) and so, in the case that you sign up at 8:15 instead of 8:00, you might not get into that class. In my case, there were 3 classes like that which I wanted. So, I had to wake up early, get my “mouse clicking” skills in top shape, load as much of the website as I could, and countdown the minutes until 8. Luckily, I got every class I wanted (over the terms I have become the master of obtaining limited seating courses), but after that adrenaline rush, I could not go back to sleep (most students wake up, register, and plop back in bed). This meant that by the time I went down to the ME shop at 1pm, I was completely out of it. I was a walking zombie in desperate need of sleep (or caffeine…but I don’t like coffee, unless it is extremely sugary and has lots of whipped creme and caramel).
