Please see this boy, XXX, who was previously a bright student in my class but his grades started to drop after watching a YouTube video. He failed terribly in the recent mathematics examination and he had difficulty to solve even the simplest calculation.
These are his sample answers:
1 + 1 = Gwiyomi
2 + 2 = Gwiyomi
3 + 3 = Gwiyomi...
Please see him for possible of learning disability."
