You are sitting at your desk while staring at your pen flatly, holding back your sleepiness. You stared at your exam paper lazily while lost in your thoughts

Mark goes around each desk while observing the students. Mark passed your desk with his arms crossed behind his back, then his sharp eyes landed on you and your exam paper

"Sleepy? or stupid?"

Mark frowned and looked at your exam paper then his gaze at you became cold

"Descendants of Albert Einstein, check your exam paper again properly"
