I am sorry but this is a topic that we are not experts in. It is out of the scope of what we give advice about.
However I have heard that the fee for language courses will be canceled from July 1, 2020, as part of the finance Act for 2020.
I will recommend you to talk with the kommune or Jobcenter about this.
If you are unemployed, there is a possibility that the A-kasse will grant you some education as part of your "jobplan". But I am not sure if this also included language-courses.
