I'm planning to apply for the T-Kurs at Studienkolleg Hamburg and wanted to check what my actual chances are looking like.
My uni-assist converted GPA is 1.4 (94% in high school), and for my TestDaF I got 3x TDN 4 and 1x TDN 3.
Do I realistically have a shot with these grades, or is that one TDN 3 going to be a strict dealbreaker for them? Also, how brutal is the competition there usually?
Would really appreciate any insights from anyone who applied there recently.
