Hi andrestoga! Well, speaking for myself, it's my first time applying so I don't know if it has proved useful for others, but for me, it isn't useful at all. I still do it all the time any way. A friend of mine who was applying last year told me about checking the GradCafe results page many times a day and I thought that was a pretty bad idea, as it made her even more stressed out and I couldn't see what good it could possibly do. Yet here I am checking the results page several times a day, even though I know the schools I'm applying to won't even send out admission replies until March. I look at the students' comments on the results page, their GPA, etc. Maybe part of why I do it is to try to predict what's gonna happen, maybe to gain some sense of control in a process which I don't control at all anymore since my applications are already submitted. It's irrational, I know. Maybe I think if I know in advance I'll be rejected it'll soften the blow a little bit. Another part of it I think is feeling all these other applicants are pretty much going through the same feelings I am, and there's a sense of community.
What about you? Are you completely zen in waiting for your reply and not trying to predict the unpredictable?
