So, my school does benchmarks, and the website uses "test tickets", which is just slips of paper with your login info for that test. Most of the time, you throw it away, but once, teachers wanted them handed back. My brother and I did not get the memo, and thought to destroy it via consumption (mineral deficiency.). Teacher walks by, asks for ticket. I tell her I ate it. General befuddlement ensues. Next year, same tests go out. They added an extra 15 seconds to the instructions, saying not to consume, modify, or destroy the test tickets.
