I am not understanding what is going on. The beta courses that are being released can be acessed for the normal users? I am not being able to access any course, is it normal? When it will be possible to use them?
The courses that are in phase 2 and 3 can be accessed by anyone. Go to your settings menu and you can access them there.
To access a beta course, it's simple. Just go to settings and they should appear in a drop-down. Note that they are all learning English, and are from Russian, German, and Dutch. Good luck!
