Did You Know? All Nighters Hurt Grades

So this survey finds that all-nighters hurt grades.

"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."

I had a thought. What if, poor students do poorly because they don't study for classes. How do you measure not-studying? Well, a measure of not-studying could be all-nighters.

The way they should have done this survey is included another variable - how many hours do you study? This way, they could isolate the whole sleep thing with someone who finally decides to study the night before the test.

This brings back memories about studying in the dorms. They smelled and the chairs and people were uncomfortable.
