Seriously. Students walked out of their exam at a Scottish school recently when they came to the question to compare Hamlet and King Lear. The problem was that they'd never been taught King Lear. I can sort of see the dilemma. It's not like you can get away with saying "Aw come on, you should have studied the entire complete works on your own." Especially King Lear, for pete's sake. You've picked the two greatest plays in the entire canon.
