Mathematics GRE

Hola Amigos! I have the good fortune of being accepted to several PhD programs, including UMD and Purdue. Also, I was waitlisted at Rice, UNC and SSCU. I was told by the program director at one of the schools where I'm waitlisted, that I'm a gold quality candidate and in strong contention. Guys, I 'm currently in a conundrum and I request y'all's help. Thanks!!
P.S My field is Algebraic Combinatorics.
