I enquire about additional requirements. Are there:
- aptitude tests (Aptitude tests at the University of Potsdam)
- specific language requirements
- restricted admissions, etc.?
I enquire about application deadlines, the application process and required documentation. Of course, I also consider my criteria for location (social and cutural environment, sports and free-time opportunities, etc.)
In short: Having considered all specific circumstances, apply to my chosen university.
