Dear nadakhayat,
First of all: the German language Medicine program at Uni Hamburg ends with state exam, not bachelor's degree.
A preparation course for international students to aquire German Language proficiency is not offered by Uni Hamburg. Instead the Studienkolleg Hamburg offers two different courses for international prospective students, but to apply for these you will need already good German language skills.

Experiences have shown that Uni Hamburg receives a large number of applications for the programs in Medicine and Dentistry, so the grade plays an important role in the allocation of study places. Applicants from non-EU countries have different options for improving their grade and thus increasing the chance of a study place. You will find an overview of the various options for improving your grades. Successful participation in the TestAS is one way of improving your grade next to very good German language skills.
