Hi friends I am a high school student and I'll be going into college next year. I will likely be attending Grinnell College, with the initial intent of majoring in physics. (I do not need the talk of possibly changing interests, I realize that; I am planning for all possible outcomes) It is of comparable price to the other schools I have been accepted to (after need-based financial aid and scholarships are applied). I am looking at around 40k debt by the time I graduate from undergrad. 23k of those loans will be subsidized federal ones that I can defer interest accumulation until I finish school altogether. If I am possibly considering getting a PhD at some point, is this too much debt? Is it doable or possible? The only major concern I have with doing this is that it may be hard to pay off on a post-doc salary if I decide to go that route.
