Reminds me of something from a few years ago. I was attending a community college, in a Physics class, which was also being taken by several young ladies in the nursing program. They were complaining one day about Physics being a required course, and the instructor said, "Hey, if you are not smart enough to pass this class, I don't want you giving me medicine in the hospital!"
On my way to a degree in engineering, I found myself in a chemistry class full of nursing students. To me it was pretty easy and I would always finish the tests in 5 or 10 minutes and leave. Later some students told me that I would intimidate the rest of the class who had to use the entire hour and still couldn't finish the test.
