We did a very boring section on linear perspective. I agree it's important. I agree it was worthwhile to spend as much time as we did on it. I also personally think it was one of the more agonizing activities I have done in a goodly long while.

Imagine sitting at a sawhorse, four class periods in a row, three hours each time, drawing boxes or other stuff, getting the vanishing points right. Add on top of that an assignment to do something similar at home, and you get the idea what was asked of us. For some odd reason, I sort of missed the homework part of this; I wonder how that happened?
