So you've heard of early morning classes, right?
The kind that no one wants to sign up for?

Well these days, some colleges are give new meaning to the phrase "burning the midnight oil" -- they're actually holding class in the late-night.

USA Today reports some community colleges are having a tough time with space and faculty, and a lot of students are signing up for these classes.

In today's Mid-day Extra, we look at the benefits -- and possible harms -- of going to school in the middle of the night.

To learn more about the practice, we went to Norma Kent of the American Association of Community Colleges.

She said that for many students, attending classes past midnight might be the only time they can take the class. If it comes down to not getting the education at all -- and getting stuck in a low paying job, for example -- losing some sleep is the least of the students' worries. Some even perform better on the new schedule.

The practice started a few years back at Bunker Hill Community College in Boston, and has since been spreading. No word yet on whether Harvard will soon follow suit.

The real question is: what should you pack in your lunch box for those late-night, in class cravings?
