High school, taking French classes is conpulsory for all Dutch teenagers. When doing the course line preparing for a higher follow-up education like University, the minimal required time spend on French is four years. For me that was 20 years ago but whatever you learn as a kid you never forget. Same with German (But I did that for 6 years). English is conpulsory for the full length as of course Dutch is.

Best of luck !
