I still remember when I took two plant field courses at the university years ago. Every week there'd be quizzes. Usually he'd put out specimens of the plants the class had ID's the week ago on forays and field trips, and then we'd have to write out answers on each one. Like common name, family or botanical name, sometimes botanical details like what kind of leaves or leaf arrangement, for instance. Points off for spelling! We really studied! But still, I enjoyed those classes more than my other classes!
