As long as you don’t speak, the Delft method sees you as an absolute beginner. Why? In your first conversation class, you start talking from the first second on. However, your understanding of Dutch helps. How? you will struggle less than the students who start from scratch. Yet, you must start with Module 1, just like anybody else who is not able to say more than ‘Goede morgen’ and a few other words.
In case you want to try out whether Module 2 might suit you, use the contact form to ask for an intake test of 45 mins with a teacher on Zoom (€ 30,-).
