Can you apply to study in Germany without completing your first year of university in Turkey?

Yes, if you have a general Lise diploma and were placed in a Lisans programme of at least 4 years at a faculty with more than 180 YKS points, you can apply directly without studying in Türkiye at all. The idea that everyone must first complete a year at a Turkish university is wrong; it depends on your school type and placement.

#Direct application without prior study

• 12-year general Lise, more than 180 points in SAY, SÖZ, EA or DİL, and placement at a faculty: direct access to the placed subject and related subjects, no Studienkolleg. You don't even have to enrol in Türkiye.
• Same, but placed at a university-affiliated Yüksekokul: direct access to Fachhochschulen only.

#When a year of study makes a difference

• Meslek Lisesi with more than 180 points: normally a subject-oriented Studienkolleg. After one successful year of Lisans study in Türkiye, direct subject-restricted access instead.
• Only one year at a 2-year MYO without a diploma: Studienkolleg route for Fachhochschulen only.
• Lisans at an Açıköğretim faculty: direct access requires two successful years.

#If you have no placement

Official sources define no general route. According to the DAAD admission database, a Lise graduate who did not take the YKS, or only has a TYT result, cannot be admitted. A score without placement gives no automatic admission and no automatic Studienkolleg; the university or the Land authority decides.

For uni-assist you upload the Lise Diploması and the YKS placement page (university, faculty, score type). The final decision rests with the university.
