Hi @amstu! I am in the same boat as you. I am also focusing on 19th c Am., working on a WS over the summer, and trying not to drown out my fears about the GRE (and basically everything about applications) with copious amounts of wine.
I am split between a couple PhD and MA programs I am interested in (I'm coming into senior year of undergrad this fall), but I haven't felt comfortable enough to nail down a definitive list. I'm hoping to take the summer to do some studying on schools and the GRE/subject test and hopefully have myself somewhat together by classes in September. I would be glad to pace with you over the summer if you're looking for a study buddy.
