interview at TCU

Hi all! First of all, I am really glad this forum exists, because everyone seems really supportive of each other! I have my first interview at TCU in two weeks and I'm not overly nervous yet, but getting there. I have been trying to refresh myself on some of the things I think they may ask, but I'm nervous they'll ask me that one (or two) thing that I am not well versed on. Has anyone interviewed there yet, and if so, how did it go? Where they pretty non threatening? Good luck to everyone applying, I know how hard you've probably been working to get this far!
