Chemistry students at the University of Colorado will be excused from their Tuesday night midterm exam -- but only if they can show a selfie proving they were caucusing instead.
The Daily Camera reports that roughly 1,200 students are scheduled to take the exam for an introductory chemistry class at the same time as Colorado's caucuses, which begin at 7 p.m. Tuesday.
Chemistry department chair Carl Koval says cancelling and rescheduling the exam would be a logistical nightmare.
So he decided that students who talk to their professors in advance can get an excused absence. Since those absences normally require documentation, like a doctor's note, Koval asked students to take a selfie to prove they were actually at the caucus.
