Stuff figured out = waking up on time for an exam? There are certainly things that aren't going to be figured out by college but dang, you're setting the bar madd low.
It's figuring out how not to oversleep for an important occasion, not figuring out the meaning of life... I mean, some people this age are working responsible jobs or serving in the military.
Yes, certainly. No argument. But when the stakes are high, a little back up doesn't hurt. It is just as much an excuse for some last minute good wishes anyway.
In any case, everybody has different circumstances. Parenting is an improvisational pursuit, every kid has different needs. In my kid's case, end-of-semester sleep deprivation has more than typical impact because of hypothyroidism that requires carefully adjusted medication and really benefits from a regular sleep schedule. Engineering school? Regular sleep schedule? Pffft. So I cut some slack. Their tendency to over-sleep alarms is partly wonky body chemistry.
I recall oversleeping for a final. Luckily, it was an intro programming, you-mean-I-can't-test-out-of-this?? class. I walked in a hour late, and left a 1/2 hour early. Had that been DiffEQ or similar.... errrf.
Sure, but your backup plan probably should not involve one of your parents getting up extra early to give you a wake up call. But to each their own, I guess.
This is one of the reasons that pre-booking taxis is a good idea. Typically, they'll call you when they arrive, so they are a really good back-up alarm clock.
