Hi! I'm looking for information on scholarships and masters programs in Germany, Switzerland, or Austria. I want to study Ecology/Conservation Biology/Natural History. Kind of a specific request but if anyone has any information at all, I would be much obliged! I don't speak German fluently yet so I need to find a program that teaches in English, which from the research I've done looks doable. I'm having a hard time finding scholarships. I've found a few programs, but it's sometimes difficult to find them! I could apply as either an American citizen or a Swiss citizen, because I have both. Also, do I need to take the GRE if I do a master's in Europe? Thanks for any and all help!
