On the second day of freshman year my AP class had a test on what we read over the summer.
My teacher left the room as soon as he passed out the test to make some copies. As soon as the door closed behind him, my friends and I started yelling the answers across the room. We didn't get caught. He thought that since we were in the only advanced class in our grade we were mature.
Oh how wrong he was.
This is literally how my high school works...
