BALTIMORE (WJZ) — An Anne Arundel Community College teacher says he learned a valuable lesson about being specific on his first test day of the semester.

Reb Beatty, who teaches business administration at the school, says he typically allows a “3×5 notecard” for students to use as a cheat sheet during exams.

“Today, a student shows up with this,” Beatty wrote on Facebook caption of a student with a jumbo-sized test guide.

“Sure enough, it is 3×5… feet. As precise as I am, apparently I never specified inches and therefore yes, it was allowed. Well played and lesson learned for me.”
