I had a very edge case.
German is my second language and I was very good at it but I haven't practiced it in 20 years when I moved to Munich. Wortland was the perfect thing I needed. Plain and simple I needed someone to customise a course for me that would not ignore the basics I have forgotten but also not going through all of them without covering more advanced topics that I needed in everyday life.
And all of that happened while I was juggling work and new life in Germany.
After looking around for quite some time I found Wortland and they've provided the best experience for my needs.
I would highly recommend them to anyone to try.
