really depends on school and program. some send out people they are putting up for fellowships first...then other assistantships...and then unfunded applicants (if they have each of these things)...super school dependent though...I always say it ain't over til it's over and I get my answer!
Yeah I would call them and then the graduate school itself if they dont have them...these things [at least for some people] tend to get lost in the shuffle...clerical errors are sadly considered applicant errors
