But spaghetti sauce can be switched for your next meal if it taste bad. A school not so much, if attended a bad school for a while you might not be able to catch up on a good school, or you have to start over again, or they don't even let you into the better school.

I remember the case of private school in Germany, which failed to prepare their pupils for the final exam of the state and all students failed. After that it turned out their curriculum was wrong. The pupils paid the price for the failure of the school. The school closed and the pupils had to repeat the year.
