Because it was the only way to get a high level of Dutch in a relatively short time (4 months), I chose a Skype course from The Dutchess. Furthermore, due to my work I did not have enough time to go to a language school for each lesson. The advantages are: the lessons are personal, intensive, easy to follow from home. A sometimes bad internet connection can be a disadvantage and no “real” contact between teacher and student. The grammar is well covered and repeated. The preparation for the State Examination is very authentic with old exams to practice with. Good feedback. I would definitely recommend an online course at The Dutchess. The reasons are the above mentioned advantages and the good teaching method.
