This teacher is quite suggestible. (Via)

Forget studying, schoolkids. Just appeal to your teachers' irrepressible need to complete any and all puzzles that would be considered too simple to be printed on a family restaurant's place mat.

The teacher who shared this on reddit claims that to have stumbled upon this student's attempt at grade control after several days of grading papers and thought, "Oooh. Wait a second..."

Sounds like exhaustion aided the teacher's compliance. In comments, the teacher assures everyone getting up in arms that it was "a legitimate 100," and to everyone chiding the teacher for possibly having given the student a perfect grade simply because a simple children's puzzle game said to do so, "you need to relax. Seriously."
