I started as a low level B and I am now a level C2 in French. I use this app as a way to review and keep my French fresh when Im not in France. I have learned lots of new idioms and i enjoy the fun lessons which dont take a lot of my time 5 days per week.
The app tests listening, pronunciation as well as all the standard grammar.
You have access to all your lessons, grammar , vocabulary which is really helpful when you cant recall something.
