first I'll give you a short discription of the school system here.
you start in kindergarden (kleuterschool) until 6y/o then you go to lower school (lagere school) wich is basic education the same for all until 12y/o after that you have middle school (middelbare) where you can choose different degrees every 2 year wich each has differnt moods. like you have Global middle school (very theoretical), Technical middle school ( a midstep ) and professional ( the simplest, very practical ). for ex in Global you can choose for languages, math, science and economics and some combinations. in technical and professional you'll have wood techniques, or metal techniques. in technical you could also have Industrial science or informatics or bookkeeping etc.. so 3 times 2 years until your 18. after that you have no obligation for going to school. after that you can either choose to do a specialisation year in middle school or go to highschool or university. Highschool, universtity is not free like the obligated schoolsa are. High school is more technical, like what I do, Industrial design, ingeneering.. University is very theoretical as rights, psychologic etc..
Of course you can do eveneing school as well.
well this is my short summery.
So I did that specialisation year wich was utter crap to, so I decided to do high school, i'm in my first year and it's aslo utter crap.
