As someone with a useless degree (art), I recommend a subject that will earn you money. You can learn/study/read pursue Medieval lit in your own time.
If you do get a useless degree, I recommend not spending a ***** ton of money on it from some hoity toity school.
I don't know how grad school works, but I got into an Ivy League wanna be undergrad (W&M) with average grades and SAT score based on recommendations, my essay, and maybe my chameleon-like race (at various points according to the school I was Hispanic, Pacific Islander, and Asian).
