Hello aspirant

For studying in Germany mainly you should have proficiency in english, a good gre, ielts or toefl score and an A2 certification in German Language. If you have a very good undergraduate percentage, a good resume/profile then you may also get scholarship or even free tuition. So i would advice you to get a 320+ gre score , an equally good score in ielts or toefl and would also advice you to keep on updating yourself with new skills to improve the variety in your profile.

Hope this helped. Good Luck!
