Hmm... yeah... Well about 20% of our people in this country follow high education. This means that they can do HBO (Higher Job Education, roughly translated) or even University. We already separated children by their education level at age 11 or 12. So I started following VWO (Atheneum to be more specific, but Gymnasium is also considered VWO, however they have Greek and Latin, where I follow other subjects) at that age. It's comparable with Grammarschool; it allows you to do Uni. If you do HAVO (a level below Atheneum) you are allowed to follow HBO. And if you really want to do Uni, you can follow the two last years of VWO after it, or you can do an exam for the course at age 21, but you won't receive money from the government in order to complete your course.

Along the way I have seen people fail; being brought back to HAVO; failing one year and have to redo it. And I really hope I won't have to do that this year.
