Our happy hour fact to amaze your drinking buddies with.

College students learn very little their freshman and sophomore years.

The book "Academically Adrift: Limited Learning on College Campuses" came to that conclusion after surveying over 3,000 traditionally-aged college students. The authors analyzed the students' transcripts and their results on a series of collegiate assessment tests. More specifically, they found that 45 percent of students showed no learning gains in their first two years.

Despite this lack of acquired knowledge , the average GPA of a student in the sample was a 3.2. According to the book's authors, much of the blame for college students not learning can be attributed to professors who spend too much time focusing on their research, and not enough time tending to the needs of their undergrad students.

Another thing to blame for college students not learning? Booze.
