Thanks! I forgot to answer the other part of your post. From what I gathered from professors I talked to, the Dartmouth program seems to be prestigious and well-known, and is considered a sort of “feeder school” for the best PhD programs, since many of its alumni end up at prestigious institutions to continue their studies.
I think if I get into a PhD, it’s hard for me to take the MA offer just because I see the MA as a sort of preparation for a PhD. Otherwise, I would not hesitate to go: the professors are amazing, and so are the resources.
