Just out of curiosity, how many graduate schools should a person apply too? I want to enter into a Ph.D or master's program in astrophysics. So far I have a relatively decent gpa, 3.8+, 4.0 in major. Summer internship with possible future publication, & I think my recommendations are solid (haven't done the GREs yet), but I come from a small school not known for physics. So yeah, just curious as to how many others applied too.
