Ask about things you are interested in or curious about. It's not necessary to ask questions in order to present yourself in a certain way, unless this is an interview -- and even so I'd stick to genuine questions.
@schyler.cox Why would you recommend not taking the October exam? Most law schools take the top score, including Georgetown, Cornell, and Northwestern. If I end up with a 170+ I'll just not retake.
Well I'm pretty sure they don't admit anyone that they don't interview so it is a good sign in that respect. Congrats and don't sweat it... You're an intelligent woman and speak well... Just be yourself and you'll be fine. Good luck!
Thanks all for the motivation and good counsel - the community here is definitely one of the best parts of this program. @"Nicole Hopkins" - Believe me, I would love to! Northwestern is one of my top target schools.
