You must fulfill the entry requirements for studying at a university. Generally, this will be the “Fachhochschulreife” or comparable pre-university qualifications. If you have education certificates from outside of Germany, please see the additional information here. A cooperative study course is demanding, which is why you must be very goal-oriented, highly committed, and very self-reliant in order to graduate successfully.
As a KOSMO student, you must submit the original version and a copy of your employment contract as part of the enrollment process. The original version of the employment contract will only be required for inspection and will be returned to you.
