COLLEGE PARK, Md. (WUSA9) -- For most college students, extra credit opportunities usually come in the form of essay questions at the bottom of the test, additional assignments or a detail hidden in the exam instructions.
So when a group of University of Maryland students got a multiple choice prompt for an extra credit question (that required no additional information they needed to study), it seemed like a dream come true.
But instead they saw this.
In short, the entire class would get at least two points of extra credit, but only if less than 10 percent of students took the six points option.
It's a college exam sized version of "The Prisoner's Dilemma"
The student who tweeted the photo, rising junior Shahin Rafikian, told the Baltimore Sun the question came at the end of his online psychology final. (He chose the two points by the way).
About a week after Rafikian tweeted the photo, a professor came forward on Twitter to claim he was the one behind the question.
Selterman told The Sun he's been sticking that extra question at the end of exams since 2008.
Unfortunately for Rakikian's physiology class, about 20 percent of the class wanted the six points, well above the 10 percent threshold for anyone to get extra credit.
In fact, Selterman said only once have enough students picked the two point option and earned the extra credit.
