A high school kid went into a frenzy after discovering his teacher refused to round off his grades from a 43% to a 70%.

The enraged kid barged into his class room and started confronting the teacher. The chinese origin teacher tried to be calm and composed but the kid really took things to the extremes.

He was trying to egg the teacher on to fight him and kept screaming at him and hurling racial slurs at him. The class watched in silence as he continued to harass the teacher.
