I know he'll do fine. He's been scoring over 80% on all the practice tests he's taken, but he's still worried he won't pass and then he won't be able to take his classes this fall, which will set him back at least a semester.
So send him good vibes, please.
Either way, we're celebrating by going to Mississippi on Monday for a few days. He needs a break, and what better reason to use free hotel rooms?
