does anyone have any experience working with a 'chatroom trivia bot'

so i had this crazy idea: im a med student and we all spend a lot of time in the library studying things that are really boring and I suddenly had the brilliant idea that wouldnt it be awesome if we could get like a chatroom bot, write all our possible exam questions in it, have it constantly loop through questions (multiple choice as our exam format is); and the first person to type in the right answer gets a point and it keeps track of points.

that would be a totally awesome way to study, all my friends were excited about it and i was like yeah lets do it! then everyone left and i started looking around and realized i am CLUELESS on how i would ever do something like this..

is there like some bot program i can use for aim chat or IRC chat that could work? anyone got any leads? any help at all to get me going would be great!
