There are basically two options for the recognition of your pre-study achievements (individual recognition & flat-rate recognition). Which variant is possible for you depends on the extent of the economics part of your previous degree program. The composition of your ECTS from certain areas (relationship of business administration, economics, law and methodological foundations) is decisive here [1].
If you meet the requirements of the different economic modules, you have the choice between both variants: the standard recognition and the individual recognition. If your previous degree programme does not meet this requirement, only individual recognition is possible for you.
[1] The examination and decision are subject to the Admissions Committee or, in the case of recognition, to the Examination Committee.
