Instead of learning Dutch by browsing the Internet, is there some type of curriculum I can follow?
Dank je wel!
Hi there! I don't fully understand your question. Do you mean some kind of course in addition to Duolingo? Or instead of Duolingo? Or maybe you mean a real-life course, in person with a teacher?
A list of grammar explanations, to go along with the Dutch course on Duolingo, can be found here: https://www.duolingo.com/comment/25020107
