Yeah, I am afraid that the UMN-TC is notoriously slow at most everything.
As I am sure everyone knows, the UMN-TC screens their primary applications. It took their ADCOM one month to review mine (I used the April scores); I just fear the long wait for them to get back to me on the secondary. Even after the interview, it can take quite awhile for the committee to review your completed file and offer you spot -- months for a friend of mine.
