Hey there,

As far as I am aware you must do this Manuelle Therapie course that can last two years (I think). It is part time though so weekends and sometimes during the week ( this is what my work colleagues tell me). It costs a bit too; I think 2 or 3 thousand euro.
It is certainly different from the UK, Ireland, Oz and NZ but that is unfortunately the way they do it in Germany.
Hope that you are enjoying Berlin!
