Study: All-nighters hurt grades - Education- msnbc.com ALBANY, New York - Students who rely on working at night to improve their grades might want to sleep on that strategy: a new survey in the U.S. says those who never study all night have slightly higher grades than those who do.
A survey of 120 students at St. Lawrence University, a small liberal arts college in northern New York, found that students who have never pulled an all-nighter on average have higher grades than those who have. The survey found those who did not study through the night had a grade point average of 3.2 compared to 2.95 for those who have.
The study, by assistant professor of psychology Pamela Thacher, is to be included in the January issue of Behavioral Sleep.
