Between 7 and 8 am, the divergence in college student study habits can easily be observed. Still lingering, bleary eyed, are the all-nighters. They can be identified by papers strewn about, stress and sleep in their eyes, and a fierce determination to just get it done. They've been here since late last night, and time is running out. Marching in with a different kind of determination are the early morning anomalies, the ones who forced themselves out of bed with six different alarms in order to start working at the ungodly hour when everyone in their dorm is still sleeping. They can be identified by large, imported coffees (the cafe is out of commission till 8:30 am), copies of the NYT swiped from the security desk and exploding backpacks that say, I mean business.
"Crossover hour" commonly refers to the well-documented time between 9 and 11 pm, when early and late studiers converge, creating a traffic jam of sorts in the basement. There is another, less researched convergence of studiers though that takes place daily, particularly as we head into the height of midterm season: the early a.m. shuffle.
