Four weeks left

We're in the home stretch now, four more weeks of class to go. How to balance the kids who are all caught up and on the verge of being bored with the kids who are desperately trying to catch up?

But with college essays being the equivalent of a homework assignment to half the class and the equivalent of the Great Wall of China to others, I better figure it out fast.
