>>476939>image of a teacherWow, that actually might be a good idea. I imagine a silhouette of a man holding a stick in one hand tapping it at the other. Like picrelated, but it's a teacher stick(pointer). I will give it a thought. This is actually a bit complicated, I need something simple like a potato or a bird. But you know, you're right, it is hard to come up with a thing that will cover not knowledge or some specific class, but classes in general. I've been thinking for two days straight and didn't come up with anything either. I've been thinking about a book too, but it symbolizes knowledge not tuition, closest idea that comes to mind is self-education.
