There are some problems with education (and anything else) everywhere. But has your country arrived at anything like the American situation, where high school is worthless as a credential (e.g. does not guarantee basic literacy) and college is the new high school?

We have a three-tiered system. After elementary school, you go to either Hauptschule, Realschule or Gymnasium. Hauptschule is essentially useless, and Realschule does not guarantee literacy. After graduating Gymnasium pupils are usually aged 19 years. And university can take another 6 years.
