I was meeting with my academic adviser last week and he brought up graduate school, saying how most people go to graduate school for free. He said that both of his daughters did, and he got his Ph.D. without paying a nickel. I asked him what he meant and he said it's a whole other conversation and he'd tell me about it later. I was just curious if anyone on here knows maybe what he is talking about.
If this is the case, can I even look at more expensive (private and/or out-of-state) schools? Because when I think about going to grad school, I usually think that I want to go to a public in-state school because it will be more affordable.
