WICHITA, Kan. (AP) — Students who audited a Wichita State University course have received hand-delivered chocolate bars and written apologies after a computer glitch mistakenly informed them they failed.

The Wichita Eagle reports 67 people who audited a class called “Controversies in Kansas History” received letters that said their cumulative GPA was zero and they were placed on financial aid suspension.

Since they were taught as auditors, there was no GPA requirement and no financial aid at stake.

About half of the students are residents at a retirement community called Larksfield Place, where the class was taught. But the class was open to anyone who wanted to take it and others from around the Wichita area took the course.

Reg Hislop with Larksfield said no offense was taken after the school apologized for the mistake.
