Hello,

It depends on the university you are applying to. Most German universities do not require GATE for admission to a Master's in Biotechnology. However, some universities may ask for the GRE , especially if you are applying to a highly competitive program.

You should check the specific admission requirements of the universities you are interested in. Generally, having IELTS (or TOEFL) and a German language proficiency certificate (if the course is in German) is enough.

Hope it helps !
