Crashing and Burning at the End of the Semester

Two weeks of classes left, and the calculus students are seriously starting to lose it. This morning I gave a quiz on limits, and it was a disaster. They can't evaluate limits that they could do several weeks ago. They have made up their own versions of l'Hôpital's rule and have started applying them seemingly at random. Making this worse, they have forgotten how to differentiate exponential functions.

Most of these students can do each component skill separately, but when they all come together in one problem, it all falls apart. My task for the next three weeks comes down to reminding them of what they know at a faster rate than at which they are forgetting.
