A few colleges are offering overnight classes for students who aren't available to take classes during conventional times.
The late night courses are most popular among community colleges, which are geared toward working students.
It's a win-win situation. About 2/3rds of community college students work and many work late. Overnight classes also help relieve overcrowded campuses and classrooms.
Some students say they prefer late night classes, simply because they're night owls.
