My Middle School Math Trick

I’m proud to admit that back in middle school, I had a knack for figuring out which teacher’s desk held the answer key. Once, while the substitute was chatting with another teacher, I snuck into Mr. Johnson’s classroom and swapped his copy of the test answers with one filled with random numbers. My classmates were stunned by their sudden drop in grades. I kept my cool and never got caught. It felt like a victory against the system back then.
