I liked the online courses. It is fun to do and you learn a lot!
Downside, there were a lot of mistakes on the way, the form were incorrectly formatted or some spaces were missing, making impossible to complete the exercises if you were not aware of those bugs.

Dear Simona, thank you for your review. We are pleased you hear that you enjoyed our Dutch Advanced course. We will contact you shortly in order to discuss your point of view regarding our course. Although we were developed with great academic-quality from UvA Talen, the University of Amsterdam's independent language center, we are always open for good ideas on the improvement of our courses.
