Please correct a few mistakes in an otherwise excellent course.
Zij kopen vlees. - She is buying meat
Hij koopt bij de juwelier. - They are shopping at the jeweller.
Zij koopt bij de bouwmarkt. - They are shopping at the hardware store.
I would like to recommend this course to fellow memrisers who want to learn to use the Dutch language correctly. But be warned; you will find it boring in the beginning so learn this course while at the same time you are also learning another one, but do stick with it.
