Looks like our school exams are going to be postponed

I was walking past class 8 today and the music teacher (who's also the homeroom teacher for class 8) was scolding some students loudly in the hallway. I carefully eavesdropped and heard the music teacher say they're holding a disciplinary committee meeting. Apparently, student B (pseudonym) has 10 demerit points, and they said someone else isn't doing much better. Because of this incident, the teachers have to re-do the exam questions. It seems like the exam paper might have been leaked...? My guess, after overhearing this, is that student A, who usually has bad behavior and hangs out with a group, thought it would be funny to look at the teachers' exam papers and then leaked them to their friends... That's just my guess though, I don't know for sure. But if this isn't the case, getting over 20 demerit points is really hard. Unless the standard for a disciplinary committee meeting isn't 20 demerit points, even with a lot, a reflection meeting is held. So if they're holding a disciplinary committee meeting... this seems plausible. My friend suggested they could just create the exam questions over the weekend since there's time, but with only D-6 days left, I don't know if it's possible to create the exam in this timeframe.
