In my last year of college, I realized that I needed to take some math if I wanted go into science. I hadn't taken math since 10th grade, so I retook precalculus for a refresher. The next year (after graduating) I returned to take Calc I, which I had been dreading. But the professor was a relatively young guy, an enthusiastic and lively teacher. And did I mention he was cute in a shaggy hair, round glasses, chalk-on-the-pants kind of way. I wouldn't say that I had a crush, but I certainly didn't mind going to Calc I class.
