I have a little note pack of things I need to remember... biconditionals, valid/invalid argument forms! I review it every morning while I blow dry my hair! (multittasking FTW)
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.
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!
