Don't take that course

The first course I taught was a sophomore level stat methods course for
business school undergrads.

Our department also taught a graduate course in Stat Methods for Social
Welfare Students as a service course for MSW students.

MSW students who had a stat course as an undergrad were exempted from the
graduate state methods course. It was taught by our department head.

A graduating senior wanted to take my course. She was going to enter the
MSW program in the fall. She needed my permission and my department heads
permission to take my course because she didn't have the freshman math
prerequisites. My department head told her, "Don't take his course, wait
until the fall and take my course". She expfressed concern that she might
make a C and couldn't make a C as a graduate student. "Don't worry about
that. Just wait and take the course that's designed for someone with your
background and interests". She insisted. We gave her permission.

She made an F. A clearcut F. I consulted with my department head about
what to do (It was the first time I'd ever taught a course). He said, "To
hell with her, I told her and she didn't want to listen."

She didn't just need that course to get the graduate course waived. She
needed it (as an elective) to graduate.
