I speak German, though I am not fluent. My reading and writing is far better than my conversation skills. My proposed research project, though, relies heavily on my German reading skills. Are you a full-grant, or ETA applicant?
I also applied to DAAD...but the afternoon I mailed in my application along with copies of my proposals I noticed a glaring, careless mistake in my proposal that I thought I had taken care of in my editing phases. Turns out I printed the wrong version of my proposal (not the final version) and sent it in. So, after having a FML moment, I calmly accepted that I probably drastically reduced my chances at getting the grant. Oh well.
All the Best,
