I've heard differing opinions on whether or not it costs to attend grad school (phd) for physics. I know that if you are a TA/RA you will receive a stipend, but does that also cover tuition prices? Is this true for grad programs across the board in the US? Meaning, does this apply to Ivy league schools down to state schools? Does every incoming accepted grad student get offered a TA/RA position? I'm just trying to see how much going to grad school will put me in debt. I already have quite a substantial amount of loans out from undergrad, and I really want to attend grad school and get my phd, but I'm worried I can't afford it. Thanks for any help!
