A classroom scene is depicted where students are being scolded by their teacher for not following the rules, such as wearing proper uniforms, not using cell phones, and not studying for a test. The teacher confiscates their phones and warns them that if they don't behave, their parents will be called. The students are also shown to be cheating on their tests, which results in them getting zero scores.
Later, it is shown that one of the students, Nicole, gets good grades and is rewarded by her father, who buys her things she likes. Nicole's friends, who did poorly on their tests, are punished by their parents by having their belongings taken away.
