Are you intending to complete a Heilpraktiker (non-medical practitioner) training program?
Congratulations, because with this healthcare system, we need everyone who approaches human ailments holistically.
Whether it's the specialized Heilpraktiker for psychotherapy (HP Psych.) or the general Heilpraktiker for medicine (HP Med.), in either case, you have weeks and months of intense studying ahead of you. But you already know all of that yourself. Perhaps you're even still reeling from the shock when you realized how extensive the material you need to learn is.
