German rather than English

Rather, due to its complex and competitive admission procedure, a lot of German (speaking) students have been studying medicine in other neighboring countries, such as Hungary, Poland, Latvia, as well as Italy (*one of the most popular destinations within Europe.)

Unless you read and speak highly fluent Deutsch, it is none of your easiest destination to study medicine “in English/German.” 

Therefore, except for this specific “International English medical campus in Hamburg,” all “German” medical universities may require an authentic “preparatory” program through “Studienkolleg M Kurs,” where non-German students study biology, chemistry, physics, math, and German for about a year (or longer) unless (s)he meets “country-specific” requirements by German higher education system.
