Back in middle school, after a test our teacher would let us draw or "doodle" on the backs of our paper after we were done. Let's just say some of my drawings were depicted "violent" and "mentally troubling" but incomprehensible due to crude stickmen drawings, and none of my teachers seemed to bother me about it, not like I didn't pass those tests (don't worry, I'm better now than before). Your teacher seems very strict, expecting high standards towards grade A studenta oike you back in your time.
