In 1925, seven students went 60 hours without sleep--for science

Scientists were out to prove sleep was just a waste of time. Among the students who participated in the sleep deprivation study was the future head of the psychology department at George Washington University. Breakthroughs, discoveries, and DIY tips sent every weekday. The grueling Medical College Admission Test, or MCAT, was first devised in the 1920s by George Washington University professor Frederick August Moss. Originally called the Scholastic Aptitude Test for Medical Students, Moss developed the readiness test as a way to curb high dropout rates in medical schools.
