@Erica Thanks for your detailed explanation! I'm not sure I understand all of it, but it helps
We have 3 different types of secondairy/ middle schools, I'll try to explain if you're interested?
1. VMBO: 12-16. This is for the 'least smart '(I hate to put it so bluntly, but it's clearest to make a general explanation! I hope not to offend anyone!) kids and it prepares you for a job, not typically a real career. Jobs like: a cleaner, nurse, hairdresser, that sort of things.
2. HAVO: 12-17 : Prepares you for slightly higher jobs after a college (college in Holland is for jobs like this: becoming a teacher, for instance .Kind of 'middle class' jobs if that makes sense?)
3. VWO: 12-18: similar to A-levels in England I think. After this you can go straight to University (Uni here is for actual 'careers' so to put it). You can study things like: Medicine, law, economics, psychology etc.
It's very bluntly put, but I hopei t makes sense!!
