I just found out that I've been selected to visit a school I've applied to during a departmental conference. Both my flight and hotel are being paid for by the program, but I haven't been accepted yet. There was no mention of interview, just a visit.. Is this good news, or will I still have to beat out a lot of other candidates? (I'm a master's student, not a PhD, btw.) I know I still need to make a good impression, I'm just trying to figure how on top of my game I'll need to be during my visit.
