Reb Beatty is an assistant professor at Anne Arundel Community College in Maryland. This year he's teaching Financial Accounting — a course he's taught for many years.
Every year when he gives his class their first exam of the semester, he allows them to bring a 3x5 inch notecard with any information they can fit on it.
Beatty told BuzzFeed News this first exam is important because it tests students on "the foundational information that all students need to learn to be successful ... in future accounting courses," he explained.
"I have allowed a 3x5 notecard for years."
