Time to put learning to the test

At the start of this semester, I was asked by the university I work at to give the students a pre-test, a sort of mock exam to establish their English level. Each lecturer was presented with a USB memory stick, which contained all the items needed to give the test.

Or so I thought.

I went back to my apartment, and looked at what I'd been given: an MP3 file of the listening test, the exam paper, and the answer key. I popped open the exam paper, and found that it was a four-page document. A quick check of my printer told me that I wouldn't have the ink necessary to print out the more than 150 copies I'd need to cover my six classes, so I rang the dean, and asked him if he had a solution to the problem.
