How to an "A" for your test?

My husband asked my students and teachers, "Do you know how to get an "A" for your test?"

Looking at the puzzling faces of my innocent friends, he announced, "Don't attend the test. Then you will get an "A" for absent."

"Do you know how to get a "D" then?" He continued.

Looking at their eager faces, he announced, "Get all questions correct. Then you will get a "D" for distinction."

Die. My reputation gone.
