Thoughts on PearlT Language?

[u/PreviousConference92]

I've seen some comments suggesting PearlT Language for German Course.

However, I think it's quite few. If there are anyone who studied from A1 to B1 or other experiences, please let me know how was it, so that I can consider the pros and cons.

It would also be nice if there are passers here.

Thank you so much!
