Levels - completed all yellow circles

[Matti-San]

Hey,

Could anyone please help me with the following. I have completed all excersises so all circles are at level 5 and they are all completed. Currently I can't see anymore which level I have reached.

How can I go further / to a next level / or so?

I've search everywhere but it isn't clear to me, anyone?

Warm regards Matti
