Waste of money
I paid for a 3 month subscription. The evaluation of my level seemed to be basic or advanced with nothing in between so they started me in beginners which seemed too basic. After a month I got stuck in a loop and had to keep repeating the same test. I thought it was a bug, but Ewa told me that I had completed all the available lessons in the study section! Very poor, and I have had no response when asking to cancel and get a refund. Don't waste your money on it.
