In order to continue my studies in Germany, it is necessary that I take an exam called the Aufnahmeprüfung. Normally, when one receives an invitation to this exam, they apply for a student visa. However, this visa can take quite a long time, so I am considering taking a tourist visa for the time period of the exam and simultaneously using the invitation I have to apply for a student visa in order to proceed normally afterwards.
Is this allowed? Would there be any repercussions of this?
One complication I think is that the date of the student visa and the tourist visa may be the same. I heard that one cannot have more than one Schengen visa at a time.
