Cheating in a test

Me and my friend had a code like this that we used on small tests. We would sneeze to get the others attention and when hang fingers off the edge of our desks to match the questions and answers

Once in my English class we had this girl named Talia who would openly give answers, like if everyone was asking about this certain question, she'd yell to the teacher, "Miss, the answer is (blah blah blah), right?" And my teacher got so annoyed that now she writes quizzes, tests and essays in the principal's office.

you could still lightly tap your finger on the desk though, right?

My friend and I would blink at random intervals at each other from across the room. We didn't know Morse code, we just wanted people to think we did.

You also tap your desk, tug your ear, pretty much anything if you know Morse code
