German proficiency testing
Hi everyone, I will be as concise as possible, I want to learn German in order to study in Germany, and learning it via watching movies, reading magazines, newspapers online, private courses here in my town and by using Duolingo as well.
But, is somebody here experienced with testDaF or Goethe Institute certificate that are most widely accepted language proficiency proofs of German language?
And if, what should you suggest me to equip with, in aspect of book-materials, workbooks or something else maybe?
Thank you in advance.
