"Quietly prepared" as in what? You're just going to accept it? Or you're going do what you have to to fill in the gaps and make it not a lost year for your kids?
I'd urge you (and everyone) to go for the second option. They're your kids. They're not the school system's kids; they're yours. If you have to spend time and/or money to make sure that they actually get the education they need (because the school system can't or won't[1]), even if you have to give up some things to do so, do what you can to help your kids.
[1] I'm not yelling at the school system here. They're in an impossible situation. They can't function at 100% effectiveness in an impossible situation? No shame in that, and no surprise, either.
