Everything is possible

The grinch earned his new heart. You didn't earn that A

I know a few people who spent quite a bit to go from an "A" to a "C", it's a little different but I think if a few grand can motivate a surgeon to make that happen, a few grand could motivate a teacher too. .... or get you expelled.... yeah. Maybe don't try to bribe the teacher. .... unless you think you have enough to bribe the principal if they report you..... anyway- anything is possible if you apply the right key to the right lock. Best of luck.

Depends on what else "grows" that day.
